I`ve had my Citroen C5 for nearly three years and this fault has only just started. The boot opens of it`s own accord when the car is unlocked either remotely or with the key in the lock. Also the boot opens automatically when opening the front doors from inside after driving. Any suggestions please?

Answers

Bought my C5 around 2006. A couple of years ago our boot did the same and my husband put some oil or something in the mechanism that locks it. Afterwards it worked correctly until some weeks ago when it started again. And yesterday another old history started again - "Depolotion system faulty". Got rid of it last Spring... Annica Petersson from Sweden

I’ve had the same problem. You need to press the lock button on your key fob twice and the problem seems to clear Keith Jones from Staffordshire

I had the same problem. There is a switch that opens the lock. My problem was that the switch was making by itself and when I tried to open the boot it did not always make. I opened the handle and put a small piece of rubber in position to stop the switch firm making without pressure David from South Africa

My Citroen C5 Tourer had problems a few weeks ago. It went to the Citroen garage and they replaced the "High Pressure Fuel Rail Sensor". After it returned the eco mode stopped working. Any suggestions before I take it back?

Answers

It started to work again today. Haven’t got a clue why it wasn’t working. I drove back from my parents and noticed the engine stopped at a few traffic lights. My feel is that it probably has to be at a certain temperature for the ECO to allow the engine to stop start.

Citroen C5 2008

The blowers have stopped working on my Citroen C5. It has 2 zone controls and all the switches and their corresponding lights work except that no air flows from the vents. A very faint strange noise is heard from the fan (I think) that sounds as if it is struggling to turn. I have read a lot of postings and it seems that there may be a problem with the fan speed regulator. Some postings even show pictures of it`s location which is said to be left of the top of the clutch pedal in the foot well of the driver`s side. I have looked a few times in my car and cannot find it as shown or described in these postings. I have removed the plastic cowling located in the foot well to the front of the central console and all I can see is the plastic side of what could be the fan motor, but no regulator. I would like to know if I have a problem with the fan speed regulator and, if so, how to find a replacement and repair it? If it is not the regulator, what seems to be the problem and how can I fix it? Many thanks in advance. (2.0 HDI)

Citroen C5 2008

My Citroen C5 has just failed it`s MOT. It is only 4 years old and has done 38,000 miles. It failed because the tyre valve securing nuts have split on 3 wheels. We have been presented with a bill of £419. Can anyone advise me if this is a common problem and why this should have happened? As the car is out of warranty it looks as if we will have to foot the bill because of the MOT. We have been told by the garage that standard valves cannot be fitted because a light would appear on our screen and this would result in the car failing the MOT again. These are special valves that monitor the tyre pressures. Can anyone help?

Answers

Sorry to hear that. I would advise you to take it somewhere a little less fussy for a MOT. I used to be a tester and that is not a fail, it’s an advise at the most but at the end of the day its down to the tester. Also if the low tyre presure light is on that is not an MOT fail either. Like an air bag light its only an advise. Hope this helps, Regards Adam Price from Norfolk

You can have the tyre pressure monitors replaced with standard valves, you then need to get someone with a lexia to turn off the tyre monitoring system. Once turned off you will no longer be warned if you get a puncture or your pressures are low Dave McCartney from Somerset

I have a Citroen C5 2002 PK. The AC on the driver`s side does not work properly. The temperature cannot be changed and it is stuck on maximum heat. The problem is probably the cursor or the mini motor that opens the hot water hose to the AC radiator. Does anyone have dismantling instructions for the dash board?

Answers

Small motors on each side of the centre consol operate flaps which control the hot or cold airflow. As the flaps can stick the motors may be ok. Try switching the air fan to lowest setting with manual control and then altering the temperature control from full hot to cold and back again, allowing five seconds for movement each time. Repeat several times. You may hear the motors whirring but they are very quiet and you have to have the engine running. Leave the temp control at preferred setting and turn fan back on. I have had 2 C5’s which both had same problem. On one the plastic drive at the motor was slipping, common problem. motors are at knee height and can be removed fairly easily Bob Moody from Hertfordshire

My Citroen C5`s offside rear door won’t open. The remote central locking works on all of the other doors and the boot, but I cannot open the offside rear door from the inside or the outside. It had previously been working fine but then without any warning just stopped working. It appears to be sort of deadlocked, with no give at all. Does anybody have any idea what the problem is and how it can be fixed ie. access to the internal mechanism and probable cause of fault and potential cost to have repaired/replaced? Thanks in advance. (3.0 V6 SE Exclusive)

Answers

I have the same problem. I was quoted 440, I suspect the moter is kaput. Put your ear to the door and try the remote, if the motor is ok you will hear it. Sorry I can’t help any more Mac from Leicestershire

Could seem funny but with your rear bottom against the area where the lock is located and give a few good bashes until you will hear some unlocking noise from the door and at the same time press you key clip. After been open spray the locks with some silicone based product ... do not use WD40 or others like that, good luck Luis Valentim from Wiltshire

Bottom banging the outside door panel near the lock worked for me just 15 minutes ago. Thanks for the tip good buddy and God bless you Brian Robinson from Lincolnshire

Just found this after having problem for 3 months; did a bit of bottom banging and hey presto my doors open. Brilliant, thanks a lot Les from Yorkshire

I recently had the same problem and tried all the methods described on the net to no avail. I had a quote for £150. Not a bad price bearing in mind the hassle I had trying to open it. Then I had an idea [not a regular occurence for me], I removed the door card which is quite easy if you take the bases of the rear seats out. This exposes the door opening mechanism but the lock is hard to get at. After obtaining a very powerful magnet I placed this on the end of the child lock barrel. It supported itself by attaching itself to the door handle linkages. After three months of trying I pressed the remote and the door unlocked immediately.Dont ask me how it worked but it did and I didn’t lose any knuckles. Give it a go, it worked for me. Good luck Garry M from Derbyshire

I have had problem with offside rear door. It wouldnt open from the outside or the inside. When I operated the remote you could hear all the other all the other door locks operating but the offside was dead.

My (new shape) Citroen C5`s cruise control has stopped working. It started to not work now and then but now it`s stopped completely. Any suggestions please?

Answers

Not sure if it’s the same, but most cruise controls are disengaged by a small switch under the brake and clutch pedal (if manual). Sometimes these switches get a bit sticky and need a clean or some lubricant (WD40) Sometimes giving the pedal a "flick" will get the switch working again. I know a new switch for an Audi (not usually cheap) is only a matter of a few pounds so if the switches are the problem, it might not be too expensive to fix.

My Citroen C5`s offside headlamp dipped beam bulb failed. I cannot get to the back of the headlamp to replace it and I have just been quoted £119 for a replacement bulb. I wonder how much the fitting charge will be? (exclusive)

Answers

About £600 at a main dealer including bulbs (change in pairs as if one has gone the other will follow and the hassle of changing makes it the better option. Cost is because the front bumper must come off and headlights removed. I did mine myself but it took about four hours by the time. I’d also removed the under-skirt, the headlamp washers, wing interior shields etc. Phil Burton from Derbyshire

The best and quickest way is by the removal of the front bar, and taking out the headlights. My son did it in 30 minutes flat. Sorry, a bit far for my son to come over Ron Webb from Australia

We have just replaced the drivers side dip beam bulb. We removed the 4 bolts along the top of the bumper and 1 on the inner wing. The bumper can then be pulled forward to gain access to the 2 hidden bolts, remove these and the one on the top and you can jiggle the head lamp out. Bulb replacement is then easy. No need to remove the bumper.This took about half an hour, and is a lot less hassle than trying to get your hand in the gap and into the back of the headlamp Jim Mercer from Hampshire

What year/ shape is your C5? Just had mine done (both as was told if one goes the other will blow shortly) for £9 labour + bulbs (1.6 HDi 2005 facelift). Mechanic wouldn’t let me into the workshop (Health and Safety!) to see what he did! Mike Lane from England

I purchased 2 x long life bulbs online for under £13 (20% off due to world cup!). It took around 10 minutes to change both bulbs, very easy. Open the bonnet, lift the centre of the two retaining clips holding the grey shield that hides the light fitting place at the end approaching the bonnet catch, then pull out the retaining clips. Lift the cover and unclip from the hidden clip at the opposite end of the grey cover by applying a firm upwards pressure. This reveals the back round dust cover at the back of the light fighting. This can be removed by twisting in a similar fashion to removing the top of a glass jar. Once off, this reveals the back of the light bulb mounting and the electrical connector that also acts as a retaining clip. Firmly pull of the electrical connector which reveals the bulb. Hold the exposed electrical connectors on the back of the bulb and pull the bulb out of its mounting making a note of which way round the bulb is seated. Now put in the replacement bulb being careful not to touch the glass. Some advocate wiping the glass with an alcohol wipe beforehand, but I believe this is only required if you have accidentally touched the bulb in the first place but stand to be corrected. Put the connecter block back in place ensuring that it clips in properly, then return the dust cover and the grey shield, test lights, viola job done. No need to remove the bumper or battery, no scratched hands, no tools required, a couple of minutes work once you have done it once. Richard from West Midlands

Unless you are insane don’t mess around with secondhand parts that have anything to do with your brakes. You can cut corners with some other things but not with primary safety equipment. As parts get older they become unstable. They blow fuses or fail or produce unreliable results. Don’t chance it - use new parts Ashley Groome from Australia

Tim, I’m sorry I can’t answer your question but I have a 2009 c5 Exclusive and have the exact same faults on my car D O’Rourke from Lanarkshire

Hi. I had same on a 2008 C5 Exclusive, turned out to be a short in the fuse box. Main dealer found problem in a few mins and would you believe they had one on the shelf. The sort of thing you always have in stock!! Only takes a few mins to change so I guess it’s a plug in thing. That was some months ago all fixed now no more problems. Rest of the car goes really well. If it’s not the fuse box it could be the hand brake cables have stretched from the actuator to the callipers but my first port of call would be the fuse box. Has the car been steam cleaned under the bonnet, water ingress would cause the problem Richard Starkess from Lincolnshire

I had same problem with ESP / ASR on my 2009 C5. It was a faulty fuse box and was replaced under extended warranty by my Citroen dealer. It has NEVER faulted since. Apparantly (according to the dealer) it’s a common fault but you don’t get a fuse box for free unless you have a full service history. I use car for work, it’s now nearly 4 years old and has done 160,000 mile (yes you read it correctly) and it has been a superb car John Watts from England

Yes I have almost exactly the same fault with sudden engine cut out on my 2008 C5 Exclusive 2 litre HDI. The dealer has diagnosed the fuse box following an info rapide (or whatever - a maintenance bulletin from Citroen). The bulletin advised on a fuse change following the fault code identification and if the code is not cleared to change the fuse box. The fuse box looks in excellent condition, but who knows with these other experiences seeming to agree a fix, perhaps I’ll be lucky, but I wont hold my breath. I have to say though, a fault which loses everything is pretty dire - on my occasion, I was 30 secs from entering the run on to the M11! Mal Bannister from Cambridgeshire

I have a Citroen C5 2004 model diesel automatic. The dashboard is reading "Depollution system faulty" and also "ESP / ASR faulty, water coolant too low". Can anyone help me as it`s risky seeing such warnings?

Answers

This is the dreaded diesel particulate filter. It is getting blocked and needs clearing. If you can get some time on a non busy motorway, drive for about 20 minutes at around 60mph. If it has gone too far it may need garage attention, ie removal and power jet clean. You would know that, if the power is poor. The additional messages are simply C5’s HAL (computer) getting excited Dennis Ambler from Wales

Your generator might be worn out, and could be resulting low voltage that causes all of those fancy errors Seza Palaz from Russian Federation

Water coolant low is probably just a level sensor or wiring, and is a separate problem. Water can be checked manually. Depollution system faulty with ESP/ASR is probably a vacuum leak and will prevent the turbo from limiting causing the engine computer to limit RPM. Will also prevent the ESP/ASR (traction control ) from working. These faults usually occur above 2000 RPM when the swirl valve operates. The swirl valve actuator uses vacuum to operate from the same vacuum pump as the turbo and ESP/ASR This shows up on a hill or at higher speeds or fast acceleration usually. You can block off the vacuum line to the swirl actuator, the car will still run ok in order to prove this. Swirl actuator is not expensive but awkward to get at. The pollution filter would show a pollution filter blocked warning Bob Moody from Hertfordshire

Citroen C5 2009

I am having problems with bluetooth in my 59 reg Citroen C5. The phone connects perfectly to the MyWay system and all of the functions are available in the menus etc, but whenever I make or receive a call the person on the other end of the phone can’t hear me although I can hear them perfectly. I’ve had the car for three months and up to last week it was working fine. I’ve done a factory reset but still no joy. I’ve even tried a different phone and it still does the same thing. Can anybody help please? Thanks. (VTR+NAV)

Can anyone tell me how to find my Citroen C5`s car code?

Answers

By car code do you mean the VIN, Vehicle Identification Number? If so, you can read it through the glass at the bottom of the windscreen on the passenger side Dennis Ambler from Ceredigion

My Citroen C5 has water coming in at the driver`s footwell when it rains. I cannot find where it is coming in from. Any ideas? (138hdi Exclusive)

Answers

It might have had a new windscreen, or an A-frame pillar repair. Put a hosepipe to the glass and fold back the carpet to see where it`s leaking. Hope this helps David from Yorkshire

We had this problem for over a year and it was traced to the drain from the base of the windscreen. It meant taking out all the carpet and having the pipe re-sealed. This was not completley succesful and in the end we had a new part fitted John Young from Cambridgeshire

I had the same problem. A mechanic friend told me the problem is to do with drains getting blocked and it can happen at both sides not just the drivers. I had to take the wipers off to let me remove the plastic cover which runs across between the bottom of the windscreen and the engine compartment. This lets you get your hand down into a well that has a drain hole at the bottom and it is this hole that gets blocked with leaves etc. You’ll probably find that this well is fairly full of water. It fills up to a point where it can leak into the foot-well inside the car. Every time it rains after this the inside gets wet. Clear these leaves etc out and you will see a stream of water flowing from the front wheel arch area. I now keep an eye on this by checking for that water at the wheel arch whenever I am defrosting the windscreen with warm water. Hope this helps Andy from County Antrim

The headlights flicker on my Citroen C5 diesel and I just can’t find how to rectify this. Would a higher amp battery solve the problem? I have had cars pull out in front of me thinking I was flashing them to go and oncoming cars flashing me. Can anyone advise me?

Answers

Mine also did this, but I never had serious problems like people pulling out. It`s down to the electrics on the suspension. When the car self levels, the spike dumped down the mains by the servos causes the flicker. There is a cure involving a large power resister like the old cars used on the alternator, but I can’t remember how it`s wired. You can find the solution online, possibly in Citroen forums. My old C5 was good at blowing headlight lamps, 3 in 18 months! A better solution is to change it for a Mk 3 C5.  Brilliant Steve Thornley from Lancashire

Hi. My Citroen C5 has done over 80,000k and has recently developed a small engine oil leak from the main bearing oil seal (between the engine and the gearbox). I’m guessing that this would be a very expensive fix or maybe not? Any suggestions? Thanks. (2.2 HDI Exclusive)
