Hi Barrie, check the level of your steering pump fluid. It could be very low or empty. Godfrey Maguma from South Africa

I use my Citroen C5 between short distances. After 4 days I used it yesterday for a 1 km and a half and I parked it. Today when I tried to start it my car did not start and displayed a message "immobiliser fault". It reset the CD player, date and time etc. on the display. I tried a number of times, the result was the same. Could the reason be that the battery charge level is low? (SX 2.0i)
Hello, yes it could cause this fault, a fully charged battery will have 12.8volts but if it is less that 12.2volts it needs charging. Another problem is batteries do not like being flat many times or for extended periods and sometimes this renders them useless as they don’t recharge properly. Also note it is possible to have a fully charged battery that has failed internally that will drop to less than 9.0volts when cranking, if so it needs changing. You must ensure your battery is okay before looking at other faults. Martin (Master technician 20+ years) from England
Definitely, the fault is caused by low battery. Recharge the battery or jump start. When you replace the battery, switch on your key for a minute, switch off, switch on again for another minute, switch off again and then start. Trying to immediately start the car after battery replacement or boost won’t work and the immobiliser fault will keep on displaying until the computer finishes initiatising the key recognition procedure.

My Citroen C5 was used to jump start another car, immediately after doing so the stereo stopped working, It still ejects cds and lights up but it isn`t showing properly on the display panel, you can`t even navigate to the icon for the stereo, in fact it looks pixelated! I have tried disconnecting the battery for a good half hour to no avail. Please can someone help as Citroen have told me I need a new display panel (best part of £400) but the rest of the panel works fine? (exclusive)

While driving my Citroen C5 the immobiliser cuts in shutting the engine off. If I lock and unlock the car it starts up sometimes, only driving about 100 yards before doing it again. Any ideas?

Hi, my Citroen C5 just had a service and I was quoted £76 for replacing both front daytime driving lights. I have just switched them off as one was gone. Has anyone replaced these as in the manual it advises to contact your dealer, but £76? Regards.
Go to Halfords, they only charge about £7 a bulb. It is difficult to get your hand in and this option is cheaper than a garage. Shaun Whetnall from Staffordshire
Further to the previous answer, yes go to Halfords, bulbs £7(ish)+ £3(ish) and they will fit the bulb. Unless you have very small hands it is not even worth doing yourself. Peter stubbs from Conwy

Hi. I have a 2005 Citroen C5 estate, I have changed the suspnsion pump, but did this without changing it to it`s own ecu, or black box that sits on top of the pump. I then did use it`s own but think it has confused it. I have bought another 05, C5 saloon, both are 2.0hdi. Could I change the esu off the saloon and if so what do I change? Is the esu on top of the pump coded, if so can you vigin them and where? Thanks. (diesel)

This may sound like a stupid question, but what does the "ECO" button do on the heater panel of my Citroen C5? Does it turn the AC on or off? I have it off at the moment but will I get better mpg with it turned on? (HDi)
Switches off the Air Con pump, which is driven by the engine. Therefore reduces the work needed to be done by the engine and saves fuel. James Watson from England

I was out in my Citroen C5 and I stopped for chips and when I restarted the car there was no sound from the radio, I tried factory reset as I thought this might fix it but still no sound and when I reversed there was no sound from the sensors either. Everything else seems to be working okay with it, just nothing coming out of the speakers and the same with the phone, I can`t hear the person on the other end. Any ideas? (Exclusive)

I have had my Citroen C5 since new. Lately it failed to start. The engine turns but no ignition. Diagnostics show zero problems. My mechanic thinks it is the fuel pump relay in the fuse box. This is a sealed unit and needs to be replaced completely costing 600 Euros . I`m not sure if this will fix the problem. Any clues or info would be greatly appreciated? (1.8 vtr)

My 2001 Citroen C5 has its engine management light and service lights on and it is also displaying anti pollution system faulty with a loss of power and vibrating when driving up to 70mph. I have just done the service but it`s still doing the same. What could be the cause?
Hi, Va Chiyangwa. It seems there is something wrong with your fuel pump failing to supply enough fuel or you have a misfiring cylinder, which may need replacement of the plug or coil, just have those two checked. Is "Catalytic Fault" also not displaying because those two fault displays are best friends, they normaly accompany each other? Godfrey Maguma from England

My Citroen C5 has front parking sensors yet nothing shows up on the display, If I`m in reverse the back sensors work and it shows on the display. Is this normal or do I need to have the front ones hooked up to the video or checked? Also I keep getting told I have a flat tyre/puncture yet the tyre looks fine no problems. I pump the tyre up anyway and the fault goes away but comes back days later, yet still the tyre looks fine. Is this a puncture or faulty sensor? Finally my driver`s door won`t stay open, it keeps shutting all of the time. Is this normal or does this need checking? In any answers please include if the work should be included in the warranty as I have only had the car about one month. (exclusive)
Hi. I bought my C5 Exclusive new a year later it came up with tyre puncture. I stopped to check and when I stopped to look the valve fell into well and the ring which holds it in place was in three bits i=on the alloy. Citroën fixed this free of charge. Great. A year to within a week the same happened Citroën replaced all valves again as they said there must be a problem. This time they are all steel rings instead of the aluminium ones that were originally on both times. Now my radio has no sound, so no idea on that one Ray Robertson from Aberdeenshire

Hi, I have a 2009 Citroen C5 which has recently had the front drop links and passenger side bushin replaced. Since this was done there has been a loud squeal when turning left. Also I have noticed that a cable which was attached to the brake callipers has snapped off and is hanging down. Does anyone know what the cause might be? There is also a loud rattle coming from this side of the car.
Sounds like your handbrake cable has come adrift. Yes handbrake operates on the front. Paul Fitzgerald from Somerset

Hi. I was sitting in my Citroen C5 with the radio on for about 30 minutes when a message came on the dashboard saying powersave mode active. Now the car does not want to start. Please can anybody advise me what to do?
I hope you had it fixed already. All you needed was a jump start, but normally the computer switches off your radio and activate power save mode that disables all power utilising gadgets (you can’t even open windows ). It will reserve enough power to restart your car. In this case it might also mean that your battery is worn out. Godfrey Maguma from South Africa

I have several problems with my Citroen C5. 1.My auto is sticking in "P". When you put your foot on the brake it won`t come out of P until you pump the brake pedal over and over. You can then hear a low click from the consul and then it`s free. This happens more when it`s warm or after being used. I was told to change the brake switch which has been done twice now with no effect. I have to leave it on it`s electronic handbrake and don`t feel safe. Can anyone help before I spend £100s? 2.All of a sudden the radio/cd has no sound but all of the display comes up and the rear parking sensors display but there`s no sound. What`s wrong? 3.Finally the A/C is suddenly not cold and blows like an ordinary blower. Please can anybody help me with these problems? Many thanks. (2.0L auto saloon Exec)
I had the same problem of sticking in P. I was in Spain touring with a caravan so was a little bothered! I went to a Citroen garage near Calpe and they diagnosed a faulty switch in the top of the autobox. They ordered one and I went back next day and it was fitted in less than an hour cost 60 euros.

I have a Citroen C5 and I want to change the engine oil filter paper cartridge that fits into a finned aluminium tank at the bottom front of the engine. The tank is secured by a socket head screw. Do I require any ’O’ ring or other seal, as the paper cartridge has arrived with nothing else in the box ? Answers will be very much appreciated, thanks. (2 litre diesel)
Yes, unscrew the plastic filter housing, take out old cartoosh filter (paper), wipe and clean old oil off parts your dealing with. Fit the new O ring and fit the new filter, replace top, and fill engine to correct level with oil Richie Fairhead from Durham

Can anybody help with the fitting of a 6-disc CD changer? My Citroen C5 was registered in March 2008 and was supposed to have one, but did not.

Swishing water sound coming from dashboard! I’ve noticed that a swishing water sound appears to be coming from under the dashboard of my Citroen C5. I mainly notice it going around sharp corners or roundabouts - sounds just like water moving from one side of the dash to the other (seem to be more on the passenger side than the driver’s side)! This has been the case for maybe two weeks now - but this morning I have noticed that the foot well on the driver’s side is wet! I’m guessing that water isn’t being allowed drain properly from the windscreen area but I can’t find any drainage holes that appear to be blocked! Any help appreciated. Thanks. (1.6HDI)

Sometimes smoke comes out from the hood of my Citroen C5. It lasts for 30 seconds / 1 minute and after that there`s nothing. A lot of smoke comes out. Citroen where we bought it say it’s normal, but I haven’t seen anyone else have the same problem. Is this normal?
No, of course it isn’t. No smoke should be coming from under the hood. There could be oil landing on a hot area, or a turbo letting go, but you need to go back to the garage and tell them they are incompetent if they think it’s normal Rick Ferries from Aberdeenshire

When doing a full lock turn my Citroen C5 would shudder and this would be felt through the steering. I had new tyres and the tracking was out so I had it done electronically which helped. The handbrake does not click for the first 2 inches of travel and it was found the nearside cable was stiff and had the outer covering worn away from touching the tyre on full lock. The car drives straight with the steering wheel central and has equal turns from lock to lock, so what could be causing it? (2.0ltr HDI VTR automatic)
