Symptoms
• Brake judder
• Metallic thud on stop

Fault Description
At low speed the car seemed to be making small surges as if the brakes were going on and off on their own. A slight vibration was felt through the brake pedal. When the car slowed and came to a complete stop, there was a metallic thud. I couldn't tell if something was swinging forward and banging on a static bit of the car or whether the brake discs were slipping after stopping.

Fixes
• The problem was a broken O/S/F ABS ring. My friendly local mechanic charged me £55 (parts & labour) I suspect a main dealer would be more.
• The problem was a perished engine mount. Fixed at main dealer. Cost £100.95
• These symptoms are not common to the two faults. The brake feedback through the brake pedal caused by an ABS ring fault is nothing like the thump made by the engine on acceleration and deceleration when a mount has gone. This conjoining of the faults is going to cause more confusion than it settles. The faults are all ABS and the introduction of the mounting is far too broad brush. Just because in terms of the written word both can be described as thumps is far to simplistic.

Fault Description
Antipollution fault light. ASR & ESP warning lights illuminated. Car in limp mode (low power, won’t rev.) Clean diesel filter warning.

Fixes
• The problem was fixed by flushing the FAP filter with a high pressure hose (as shown in the “how to” guide on the forum.) Did work myself so no cost. Approx 3 hours work.
• The problem was a defective pressure differential sensor which was giving false readings. Fixed by independent garage. Replacement sensor £95 labour £45

Symptoms
• Steering judder

Fault Description
When travelling at speeds in excess of 50mph, juddering can be felt from the front wheels up through the steering wheel making it "wobble". The speed in which this happens can vary from vehicle to vehicle. This issue occurs more with the "Hoggar" alloys.

Fixes
• If you have Hoggars, they are centreless and need a special adaptor on the balancing rig and they are rare and run of the mill tyre fitters won't use the adaptor very often and either don't know how to set it up or it is in poor repair. So ask if they have the facility for centreless wheel balancing and let them know that you expect problems so they need to get it right! (Above info provided by Tatsfield)

http://www.406coupeclub.org/PHPBB3/viewtopic.php?f=3&t=32475&hilit=balancing&p=340726&view=show#p340726
• Wheel judder 30mph plus. Usually only happens when garages use apprentice's to carry out work, or the fitter is low on memory. (We've all meet them)! Firstly check the wheel bolts have not become loose. Balancing would be the next check, due to Peugeot's unique design of centralised wheel balancing. Balance weights may have come off. Visual inspection alloy wheel fitment dependent. Brembo or Bosch Cailper could have a seized piston. In correct brake fluid bleeding. On Brembo calipers. Newly fitted PAGID brakes (Do not buy these pads) ill fitting and poor mileage usage. Peugeot, delphi, or drive tec all work better.



Symptoms
• Low brake fluid warning message

Fault Description
When the ignition is turned on with the hand brake in the applied position, the ECU reports a brake fault "Low Brake Fluid" and bleeps. The fault goes when the handbrake is released and does not return while the car is being driven

Fixes
• There is no real fault connected to the brake fluid level. The fault emanates from a worn handbrake position monitoring micro switch. If the switch is replaced with a new one the fault does not reappear. (I would post a link to the procedure for doing this in the new How To section but it is not possible until the separate How To has its own URL)



Symptoms
• Knocking from the front suspension

Fault Description
Knocking being heard from the front suspension when driving over a rough surface like cobbles, speedbumps etc. Usually the rubber boot splits & dirt / water gets in & wears the ball joint out prematurely.

Fixes
• Front droplinks are usually the fault. Replace these (might as well do the 2), 1 each side & are quite cheap to buy & replace yourself with basic tools.

http://www.406coupeclub.org/PHPBB3/viewtopic.php?f=45&t=35858
• If you buy cheap ones from Ebay or the like, expect to be replacing them again within the year. Try to get reputable quality items such as Lemforder. They're more expensive but are built to last.



Symptoms
• Screeching from auxillary belt area

Fault Description
Screeching sound from the auxillary belt area on the V6 when starting the car from cold. Tone changes when turning the steering wheel from full lock to full lock. Noise dissappears when the engine has warmed up.

Fixes
• Replace the crankshaft pulley, preferably with a new one.

Symptoms
• Heater Blower

Fault Description
Erratic fan speed, whether in auto or manual fan mode.

Fixes
• Having cleaned out the cabin sensor by the interior light and replaced the blower fan, neither of which changed anything, I replaced the heater controller (resistor pack), small item with heatsink attached. This is located next to the blower fan in the passenger footwell under the glove compartment. It fits into the air duct and is easy to change over with just one screw holding it in place and a couple of multi pin connectors. All is now working just as it should be.



Symptoms
• Screeching from auxillary belt area

Fault Description
Screeching when cold engine. Improves once warmed up, gets worse when power steering under load.

Fixes
• In the pipeline......:$



Symptoms
• Electric window regulator

Fault Description
Drivers window doesn't work although motor is working.

Fixes
• New regulator to be fitted.
• Window used to work "on the button" okay but it did not drop on opening - not too bothered I had to change the barrel of the drivers side lock - which I did okay Whilst I had the cover off I removed the multi pin plug to the window actuator to see if it would get the initial opening and closing drop going again - It had worked "now and then" All back no success with the window drop but window operated as before Next day opened the door - window dropped - BUT it did not shut up and the window had stopped operating Passenger side window operates okay but does not Initially drop ( though used to a few ago)



Symptoms
• battered bumpers

Fault Description
Front and rear bumpers suffered untold abuse from previous owner!!

Fixes
• Second hand replacements, when cash becomes available!



Symptoms
• Swirl Valve Ball Joint Broken

Fault Description
Plastic ball joint on swirl valve snapped, but diaphragm OK. £200 to replace at stealers!

Fixes
• Bought diaphragm for £25 and swapped plastic ball joints. This is a bit fiddly so take your time. I used some long nosed pliers with a tiny screw (about 2 mil) bluetacked to one end. This allows you to push the metal rod back though the broken ball joint and release it, then pop on the new one. I was a bit heavy handed and the rod did twist a bit from inside the diaphragm but if you gently twist it back it should still be ok.



Symptoms
• Rust on sill

Fault Description
Rust on sill by drivers door

Fixes
• to be fixed in September
• Check for play on door hinges ,as they support a lot of door,pins with just a slight wear will allow rear of door & doorseal to rub paint away then air gets at the broken paint. Also check for play on door hinge panel ,try lifting rear of door while watching for play on hingepins & hinge mounting panel. Door should close without doorseal touching sill, doordrop can also be caused thru door being badly adjusted in the past.

Symptoms
• Drivers door strap tightening

Fault Description
Drivers door strap tightening

Fixes
• this weekend all going well - just tighten it up!
• Tightened up the bolts that link it to the door as per the "how to" guide. T30 torx bit with adjustable spanner. It was fiddly but it is smooth on opening and closing now.
• Where the door strap fixes th the actual door, check the metal around the 2 mounting holes because on my car the constant movement of the strap had actually torn the metal. I need a door :'(



Symptoms
• rear view mirror all yellow

Fault Description
Rear view mirror is all yellow

Fixes
• Following diagnostics provided in the help section, new rear view mirrow needed.



Symptoms

Fixes
• Stop using the noisy pedal as much or as hard! ha! :)
• remove the spare wheel from the boot :-)



Symptoms
• Warning Bleep

Fault Description
Common air-bag drivers fault (electric seats)

Fixes
• Not fixed as of yet



Symptoms
• Vibration

Fault Description
Both rear hubs (fixed)

Fixes
• New hubs



Symptoms
• Grating noise after starting up

Fault Description
Obvious noise from the starter motor immediately after starting. Starter motor gearing stays forward against the engines flywheel, thus making the grating / grinding noise, which over the course of a minute goes.

Fixes
• Replace the starter motor. Make sure you replace the heatshield, this can be very fiddly with the downpipe in place. Refit the live & ignition switch wires & bolt them down, with the motor just hanging around, try to persuade the heatshield on & tighten it up, then bolt the starter motor back in place.

Symptoms
• Revs stuck open
• Accelerator pedal stuck to the floor
• High revs

Fault Description
Throttle seems wedged open after accelerating & lifting off the pedal. The pedal seems to sink to the floor & stay there. Engine revs are very high. This is mainly related to the V6 engines.

Fixes
• Remove the main air hose from the airbox to the throttle body, you'll probably find an oval metal band wedged inside the butterfly, remove this & dispose of it.

Symptoms
• Auto Gearbox pump bearing faliure

Fault Description
Erratic change of gears and hunting at 50KPH. Vibration.

Fixes
• Gearbox replaced by second hand with 140000 km and runs Ok.



Symptoms
• Scraping from rear brakes whilst driving.

Fault Description
A constant metallic scraping noise coming from the rear brakes / backing plates.

Fixes
• If pulling up the handbrake whilst driving eliminates the noise, you need to gently bend & manipulate the metal backing plates towards the disc with the rear of the car jacked up & put on axel stands. Trial & error, bend them around the edge inwards with your hands through the spokes of the wheel, then with the handbrake off spin the wheel, repeat if necessary till the noise goes. Repeat for the other side.

http://www.406coupeclub.org/phpBB3/viewtopic.php?f=7&t=42552
• If manipulation of the backplate doesn't cure the noise, try inserting a large heavy file between backplate and disc to remove any rust highspots that may be grating against the backplate. Hold file in place and turn disc by hand, You'll hear and feel if there are any highspots there. Keep doing that until it feels smooth.
• Had tried all of that ,would clear at top then start again at bottom & vice versa,so cut away lower section (not needed ) leaving handbrake section in place ,backplates are not part of the M O T and lower half does nothing,check the front wheel backplates ,they don't exist.
• I had a similar noise on my 3L SE. I had the backing plates changed at a cost of £400 which made no difference. A few months later I needed new tyres and the fitters found one of the wheels was warped. Found a wheel on eBay and no more noise! The wheel was badly bent and I'm not sure how it happened as I hadn't hit any curbs or potholes but problem solved.



Symptoms
• Antipollution fault

Fault Description
anti pollution fault message when starting car but goes out when running. Engine management light illuminated continuously.

Fixes
• No ultimate fix as yet - usual stuff tried - new plugs, new MAP, new coils, regular servicing etc.
• ANTI POLLUTION FAULT,GAS ADDITIVE FOR VALVE A FULL BOTTLE TO 20-30 LITERS AND FIX



Symptoms
• Knocking from the front suspension
• heated seat failure
• Scraping from rear brakes whilst driving.

Fault Description
Scrape on rear brakes was backplate rubbing on disc, have chopped lower half of backplate off & cured the scrape ,serves no real purpose and is not part of the M O T and going by the front backplates they are not needed. Front susspension only i can hear the knock, will investigate it when weather gets better. Think o/s heated seat pad needs replacement ,or do they only work with defrost system, didn't try that yet. Best thing i ever did was ,get ridd of particulate system ,had have to front end resprayed ,as i knocked paint off within minutes, as the power diffrence was unbeleivable,couldn't beleive i was driving a diesel.

Fixes
• removed lower half of rear backplates. Knock poss droplink Removed partiulate filter & re - map
• False faults on dashboard eg door open (its not) Air bag faulty or Esp faulty.To fix these faults change your battery if over 2 yrs old & only buy top quality with cold cranking power above 600 or above ,i did this and had no faults for over 12 months . I also get fed up with people wanting to buy the car .



Symptoms
• Low brake fluid warning message

Fault Description
Intermittent Brake Fluid Level Low Warning

Fixes
• A popular fix for this is to change the hand brake switch but this didn't work for me. After taking the car to 2 different garages in the UK neither could find the fault. I finally took the car to a Peugeot dealer in Spain who fixed the fault by changing the brake fluid reservoir!



Symptoms
• Screeching from auxillary belt area

Fault Description
Squeaking noise coming from aux belt area, and was advised per tensioner was worn.

Fixes
• Replacement of pre tensioner and idler pulley.



Symptoms
• clutch pedal on the floor

Fault Description
Burning smell and smoke coming from engine bay and clutch pedal went to the floor.

Fixes
• Replacement of clutch and crank sensor as well as clutch fork.



Symptoms
• speedometer dropping to 0

Fault Description
While driving the speedo drops to 0 intermittently.

Fixes
• Replacement of the speed sensor (located on gearbox).
• there are two types of speed sensor one with 3 pins and one with 2 pins the latter is almost impossible to obtain.any suggestions on converting 3 pins to two?
• I repaired my 2 pin sender by drilling out the rivets, dismantling, the fault was a leaking oil seal in the barrel.I made a tool from a piece of rod by grinding a lip to fit inside the seal where the seal spring fits and drove the seal out. i got a replacement seal from Simply Bearings Ltd, Halton House, Greenfold Way, Leigh Business Park, Leigh, Lancashire WN7 3XJ. Tel. 01942269837. part no.8X16X7TC price £2.27p ( I collected) I inserted the seal using a piece of wooden dowel so as not to damage it.I then reassembled the unit and put a thin coat of sealer on the joint between the cap and body and enlarged the rivet holes carefully to take miniature bolts and lock nuts I got from Aldi.I then tested the unit by inserting the end of the gear shaft into a battery drill, connecting the terminals across a voltmeter switched to AC scale and ran it up; on my drill I got a reading of 0-7.2 volts according to the revs of the drill. I now have to tackle the D8 intermediate unit between the sender and the speedo Any suggestions on how to identify it from allthe units behind the glove compartment?



Symptoms
• Faulty brake lights

Fault Description
Rear brake lights, including the window LEDs, are either all out at the same time or on permanently, or flicker intermittently. You will likely only notice this when it's dark or a police officer raps on your window to ask you to sort your lights out.

Fixes
• If you have ruled out a blown fuse, it is likely the brake switch is broken/malfunctioning. The switch is a small plastic component that sits at the top of the brake pedal arm and is a bugger to get to. Roll the driver's seat all the way back and sit on the door sill with your legs on the drive, shimmy under the steering wheel until you are lying on your back with your head looking up at the pedals. Oh, before you do this painful manoeuvre, grab yourself a torch... You will see all sorts of gubbins above you so focus on the brake pedal. Right at the very top you will see a small black component that looks like a big fat screw. If you can't see it, press the brake pedal and you will see a little nipple-like protrusion between the arm and the metal fixture it is attached to. Wiggle it out of its hole and it will come free with a wire attached to it. Pull it off its attachment, replace, and re-position. If you haven't passed out by now with all the blood rushing to your head, consider yourself a genius and tell all your mates how clever you are. Replacement switches cost around £6 to £12. In my experience, they are flimsy and don't last very long, and as they are difficult to put back into position they are easy to break when you develop a mild rage, so buy two.



Symptoms
• Squeaky brakes

Fault Description
Excessive and annoying brake squeal when slowing to a stop. Pedestrians will look at you like you are driving a wreck, dogs will howl, and small children will cry.

Fixes
• Ruling out warped discs, it's likely your mechanic fitted cheap brake pads on your last service. Have them replaced with some more upmarket ones and you can now brake without fear of ridicule.
• I have my second 406 Coupe (3L)and have never been able to get rid of the brake squeal - until now? I left the car with AutoLusso, Bournemouth who did a complete brake rebuild and have got rid if the noise. The Brembo brakes on the Coupe are the samea as the brakes used on the big Alfa Romeos which have the same problem. The cost was £300 however I would say that driving without the squeal. is spooky!! Speak to Lawrence or Paul on 01202861699.
• My Coupe's (3.0 with brembo calipers) brakes were squealing terribly and I applied copper grease, ceramic grease, special caliper grease to the back of the brake pads buy everytime the squeal gone only for a couple days and come back again. So I saw that applying grease to the back of the brake pads does not work for Brembo calipers. I finally found a japanese web site which is stating that piston seals and dust seals of the calipers may cause squeal and generally overlooked. I changed the piston seals and dust seals and wipe away all the grease that I've applied to the brake pads and get rid off the terrible squealing. Its like a miracle. I lived almost a year with the problem.

Symptoms
• Trip Computer Not Illuminated

Fault Description
The backlight to the trip computer no longer illuminates it sufficiently. In sunny weather you will not be able to read it at all.

Fixes
• I wimped out and had Peugeot sort this one out, as I couldn't fathom dismantling the entire dash, but I am led to believe that the instrument panel can be removed and the bulb replaced. Cost about £50 quid at a Peugeot dealer...



Symptoms
• Moisture in rear light clusters

Fault Description
Beads of water can be seen through the plastic of one or both rear light clusters. It looks crap and appears to the stuck 407 Coupe owner across the road that you don't look after your car.

Fixes
• Since I couldn't work out how to take apart the light cluster (god help me when it comes to changing a bulb) I solved this by placing a moisture absorber normally meant for use in damp caravans between the boot lining and the metal bodywork behind the light cluster. The best type is a small 6 x 3 x 3 one with a leak-proof membrane. Pull out the boot lining (carefully) and place the absorber on the shelf-like thing you find behind it. Put the boot lining back in place and after a day or two the moisture will be gone. If it's on the side with the CD changer then it's easier because there is a flap with a velcro fastening. Insert and await results. Don't leave it in too long though...



Symptoms
• Headlight main beam failure

Fault Description
One or both headlights fail to come on despite successive bulb changes.

Fixes
• If you have ruled out a blown fuse, give the electrical attachments on the bulbs a wiggle. Do not let Peugeot dealers tell you that the entire headlight needs replacing.



Symptoms
• Vibration

Fault Description
If you get vibration from the steering wheel following a cambelt change (V6) then the mechanic hasn't fitted it properly.

Fixes
• Have the tension of the cambelt checked as it may be too tight. No easy task so best left to a professional.

Symptoms

Fault Description
I was losing coolant at a quite alarming rate! I turned on the engine and allowed it run for a while, and inspected the pipes. Lo-and-behold, I found the rogue pipe, which was located just behind the filter box - the small pipe which feeds the air con. The pipe had a small hole in it and needed replacing, which should have been easy enough you would have thought.

Fixes
• Well - it was! Just use some decent mole grips to get the clamps off, and be careful not to be too rough as one side of the pipe connects to a plastic component which you could easily damage. However, here comes the rub! Try finding the replacement part! This is where things get very tough! I went to Peugeot and not only did they not have the part in stock - they said it had been discontinued and I wouldn't be able to get one! I begged them to see if there was a similar pipe in a newer model I could adapt, but they were not having any of that! The part (had it been in stock) would have rushed be about £15! £15?! for a piece of pipe no longer than 3 inches!? Hold this thought as I get to the punchline! So off I went (with the damaged pipe) in search of a replacement... I went to every parts department in the town I could find and the only advice I got was to try using silicon piping as found in a plumbers merchants! So I went to plumb base etc with no luck at all! I decided to visit Screwfix plumbers sales counter - just in case! But again - no luck! But then fortune smiled! the guy behind the counter genuinely wanted to help me, and when one of his mates walked in by sheer coincidence they pointed me to an obscure hydraulic pipe manufacturer on the industrial estate. Well why not?! So I went there - and within seconds they had a perfect replacement pipe for me (designed for the high heat levels etc) which I gratefully purchased, fitted and have had no trouble with whatsoever. Here's the punchline... I paid £2 for over 1/2 meter of the stuff! So - whilst I encourage all to use the Peugeot parts departments, I would also urge you to not place too much credence on what you are told!

Symptoms
• Radio cracking

Fault Description
Radio cracking

Fixes
• Dispatched to Nico den Haak for upgrade and full service.
• In my case it was the soldering. Aging and vibrations and heating/cooling cycles break the solderings between the components inside the radio. After 10 minutes of resoldering of the suspicious ones, from an experienced person and another 20-30 minutes to remove the radio and disassemble it, it works as it should!

Symptoms
• Antipollution fault

Fault Description
After having purchased the car and driven approx 500 miles, an anti-pollution fault has arisen.

Fixes
• Next step I suppose is to buy a diagnostics tool and see what's behind the fault warning.



Symptoms
• ASR/ESP warning lights illuminated

Fault Description
Sometimes when going over rough road the lights will come on. also when stopping the brake pedal will feel like the ABS is activating.

Fixes
• In my case a spring from the rear shoe fitting kit was wrapped around the ABS sensor giving a false message. Remove the obstruction & clean the sensor head then fit any new parts needed.

• In another case it was only a connector issue. Removed connector to throttle unit, did a good cleaning and afterwards used contact spray on the connector. Fault went away and never came back.



Symptoms
• O/S door mirror non-functioning (N/S OK)

Fault Description
O/S (driver's) door mirror not responding to switch inputs - N/S mirror is OK.

Fixes
• TBA



Symptoms
• Rear shelf speaker buzzes with bass notes

Fault Description
Rear shelf speaker buzzes with bass notes - O/S only, N/S is OK.

Fixes
• Going to try removing the fabric trimmed shelf as there are no visible fixings for the speaker either under the removed grille or from within the boot.
• Couldn't find speaker fixings but speaker does seem solidly mounted. Noticed that a small part of the foam 'ring' between the speaker and shelf was protruding so I pushed it back in. Result: no buzzing. However, next day buzzing was back so will investigate further.
• Both speakers buzzing. Fixed temporarily with a blob of blue-tack pressing on the outer edge of each speaker cone. Will probably need to replace the speakers.
• Fitted a pair of JBL GTO938's. Straight swap, great sound! SORTED



Symptoms
• Loud metallic rattle from air-con pump pulley

Fault Description
A loud metallic rattle coming from the air-con pump pulley when a/c or auto is selected.

Fixes
• Appears to be a loose plate fixed to the outside of the air-con pump pulley. The plate has visible lugs and flat springs on the outside which don't seem to do anything. Will remove centre bolt from plate, turn it round and re-fix.
• Further to advice received from member Mark W, it seems the plate is on the correct way round. Plate spins freely and I can turn the central nut with my fingers so there's not enough resistance to get the nut undone. Will investigate further. If I can get the nut off then I can assess the damage or otherwise to the plate.
• Further investigation found araldite on central screw thread - removed that. Plate has been welded to pump with spot weld - hence no noise when I bought the car. Weld has now broken and plate free to spin. Tried filing the blob of weld down. All quiet unless I use 'Auto' setting - 'A/C' setting is not noisy but doesn't seem to work well - assuming need re-gas. I'll source a replacement pump (£30 off ebay) and get a specialist to change it and re-gas the system.
• Sourced a s/h air-con pump from member ade1122 for £30. Had a mobile air-con specialist (Cool Runnings) change the pump and re-gas for £100. Now have lovely cold air :)

Fault Description
Car wont start when hot(after 100km/hr/60mph driving for some time), initially though it was battery related, but testing showed battery condition OK. Further enquiry with a Peugeot dealer technician, suggests it is probably a faulty starter motor. Starts from stone cold. Technician suggests the small sized Valeo brand starter is inadequate for long life. I asked if repairable with say new carbon brushes & new bendix pinion bushing but he suggested may only last for a further year. He suggests replacing with new unit(but he would, as he works for dealer)! Any comments or suggestions? Should I try a second hand OE starter first up. Thanks Don(car is MY '02 3.0 V6 SE manual trans)

Fixes
• Do I try a second hand starter or is it worthwhile reconditioning my starter(car has just turned 100,000km(60,000 miles)?



Symptoms
• Noisy rear wheel bearing

Fault Description
Loud noise coming from back wheels, would calm down when steering left.

Fixes
• Bought two new wheel bearings and hubs on ebay and assembled them myself. All good.??



Symptoms
• Engine cut out (fuel related)

Fault Description
Sudden acceleration from 0mph or from moving, the rev increase as normal. Then the rev just touch the 2.5k-3k range and loose power fully. If the clutch pressed then the engine is completely stop. After 10 sec the engine starts and works fine until the next accelerate.

Fixes
• Firstst of all thanks for the forum users! I received a lot advice! Special thanks for Parm and Berti! Luckily I have a 406 saloon with 2.2 hdi engine :) So I took out a few things and fit them in the coupe. Just one in one time and test after each. Fuel filter (few weeks old) Fuel rail pressure sensor (fuel rail, behind the fuel filter housing) Fuel pressure regulator (high pressure pumps right hand side) An other sensor on the top side of the high pressure pump. Lift pump in the fuel tank (for me 6 hours to get out both and back both) So just the high pressure pump left. I found a bosch (made in Italy) for 50 quid on eB@y. Then timing kit an drive belt kit.. The local garage changed them all and the problem disappeared. Happy end :)

• Have checked fuse - OK. Will check wiring under seat at some point.



Symptoms
• Engine coolant temp too high

Fault Description
"STOP" light on instruments illuminates, car gives warning beep and display says "Engine coolant temp too high". Oh and as a brucey bonus all the dials on the instrument panel go back to their resting position.

Fixes
• Easy fix this one. Took out the temperature sensor and gave the end of it a clean with some soft wire wool. Screwed it back in and cleaned the electrical connections. Saved a tenner and cured the problem



Symptoms
• Airbag light on

Fault Description
Airbag light on the instrument panel illuminated which is an mot failure. Narrowed it down to the wires under the driver's seat. Give em a wiggle and the light goes out.

Fixes
• empty the FAP

Symptoms
• Brake pedal goes solid when stopping

Fault Description
Just as the car comes to a halt, say at a junction or behind a queue of traffic, the brake pedal goes 'solid' and all braking is lost - in fact the car seems to speed up. Cue much application of the handbrake until the car stops and the braking returns to normal.

Fixes
• Un-plugging the electrical connector from the ABS hydraulic block restores normal braking function but without anti-lock brakes or ESP. Plus the dash lights up like a Christmas tree with the warning lights!
• Had the ABS pump replaced. Brakes work, dash lights out. However, pedal is very soft on first application - a second dab firms it up. Will get the system bled again...
