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)

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.

Answers

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.

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?

Answers

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.

Dene Nicholls, England

Citroen C5

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)

Answers

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 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?

Answers

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

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

While driving at night the screen of my Citroen C5`s sat nav turned a bright yellow and I could not read the display. The next morning it was back to normal and it hasn`t done it again. Any ideas why this happened? (vtr+nav)

I have owned a 10 plate C5 VTR Plus Nav HDi 160 for a month. Shopped in a Mondeo Titanium X because I had a fault with the touch screen sat nav and couldn’t face the cost of putting it right.

By pure coincidence, my screen started doing this just today (13aug2014) - how annoying. Intermittent yellowing and fading. I see there is a bmw chatroom on such a topic.
