Hello, I'm going to by a second hand C5 but I cannot find the official variant. The company said to me that the variant is: Citroen C5 DIESEL EURO 5 AUTOMATIC 1.6 115PS and 1/2012 month/year traffic circulation. It has also extra navi system and Formula 1 steering (handle the gears). Could you please send me some details or instructions what I have to ask the company here or to have in mind before I buy it? Is this C5 variant valid according to your data and technical knowledge?

The satnav screen (and everything else including radio) has completely died. Occasionally in the past it would temporarily go blank and revert to the Citroen logo and would be OK again after a few minutes. But this is different - nothing showing whatever. Have checked the fuse (was OK but changed it anyway in case). Tried every combination of buttons to get a restart - nothing doing. Any ideas? A solution greatly appreciated!!

Citroen C5

Good afternoonWe have a Citroen C5 that was currently off road for 18 months. When we went to replace the tyres the garage said that there might be a slight leak of Hydraulic fluid and to get it checked. We took it to our local garage who advised that they couldn't find a fault in the pipes and rang a Citroen dealer to discuss. They advised that this is a common issue and is where the pipe 'sweats' (sorry if this is the incorrect term!) and we should not be concerned. There is still a little fluid on our driveway. Is this something anyone else in the know has come across before and is this correct?Many Thanks

I have replaced my fog light bulbs with new bulbs only to find they are not working, even when the engine is running they still will not work, the fog light lamp appears on the the dash console and i have checked the fuses and all seem fine, i reckon it is down to the electrical relay but i can't seem to find them anywhere, i have checked under the bonnet next the fuses, in the glove box next to the fuses and in the boot behind all the lining but all to no avail. Am i missing something? I was hoping someone might point me in the right direction with this problem if possible. Many thank's in advance, Graham.

Citroen C5

Hi, I have bought a c5 2.0 l hdi auto with a 6 speed box. The car drives brilliantly with no faults at all for the first 15 to 20 mins but after that the car will randomly fall out of gear and then when you take your foot off the acellorater and let the revs fall back down the car will then fall back into gear sometimes with a fud depending on how quick you are traveling . I have took the car to Citroen and they just charged me £224 for resealing the gearbox and changing the gearbox oil which did not fix the problem and then just said it would need a replacement gearbox. If any body could help me with their thoughts I would be most grateful . Many thanks James moore

I have just recently bought my C5 and I have a brake warning light and stop light that come on sometimes when I turn a corner, together with the anti pollution warning. I have had it checked out by a garage with a diagnostic and it is still there and they don't know what is wrong. It drives fine other than the day lights come on and off on their own when I indicate, and my wipers go really fast for no reason and when that happens my windows go up and down only once. I would appreciate any suggestions on these matters. Thank you.

Citroen C5

My car sits down at the back when the engine is off. Why?

Answers

In simple terms there are four balls one in each corner and a central Ball pressure Unit under the bonnet, but there is also a Balance unit between the front and back which could be faulty, each ball has a split pressure gasket one side is flued the other air pressured if the gasket is burst or split internally then as soon as there is no Back pressure to hold the car up when the engine stops the Ball cannot hold the flued it moves into both sections and the car sinks as the flued moves into the top section. it could be the central Balance unit or both back balls have burst inside If you are going to replace two ball then see if you can afford to do them all as it is worth it as soon as you drive it is like a new car. I replaced all of them and what a difference to the drive control and comfort. I got another 40000 plus before I sold it I saw it after the car auction at a yard and the Balls were gone within two weeks. Alexander Collins from West Lothian

Hi. I have an annoying squeek behind my glovebox that only starts when to vehicle is moving.I have emptied everything out of the glovebox and removed the fuse panel cover so nothing in there could move but to no avail I have also switched the interior fans off and it continues.It sounds like plastic bottles in plastic wrap rubbing together.I have also cancelled out the glovebox lid.I can only come to the conclusion that something is loose behind there as this only happens when the vehicle is moving.How do I get behind that part of the dashboard?I was wondering if anyone had had this problem. Any advice will help as this noise is an hindrance to listening to good music

Answers

You can remove the cardboard/carpet over passengers feet it's only held on by self tappers and comes away easily. but don't move it any more than you have to. You have to be a contortionist to do this and will need a torch. It may be the front bumper/ nosecone on that side. That is held onto the wing by a twist fastener, undo that by a quarter turn,lift the plastic bumper bit till it butts up against the wing proper, retighten twist fastener. I have the opposite, when I switch the engine off there is a squeek from the rear of the engine ! Steve from Yorkshire

Citroen C5

Hi, the suspension of my C5 estate has stuck in the lowest setting, making the car unsafe to drive. There is no sound coming from the suspension pump and there are no warning lights at all. I checked the suspension fluid container (didn't know where it was until I found info on Internet) and it was empty (oops). Refilled with LDS but it made no difference. Button & dashboard level lights are working as normal, just no movement. Any help would be appreciated please!

Answers

Hi, could now just be air in the system. Get a long screw driver or piece of pipe or wood. Place it on the suspension pump under the bonnet on the right hand side under the fluid reservoir. Place end on motor away from moving parts like the belts etc. and the place on the bone behind your ear, this way you can tell and hear if the motor is going or not. Do this when the engine is stopped then do it when then engine is going so you can tell the difference. But sometime the pump does not go if their is enough pressure in the system, so you may have to do it's few times to tell. So if air in system which it could be, as it ran out of fluid. But you need to see where it is loosing the fluid. Not difficult as fluid leaves an oily mark in parts and normally if loosing this much it will be dripping on the ground. Park where the road is clean and look under it in the morning it should leave fluid below the leak. My other answer for air in C5 should explain to you how I bleed C5, suspensions, and us how the Haynes Book explains it also. You must fix leak or it will happen again, unless it is a slow leak, but will get worse, so will need to. Be done in the end.hope this fixes, from New Zealand. Ged from New Zealand
