The turbo has blown on my C4 and the battery was flattened whilst I was towed off the motorway, battery has been charged but electrics are now not right, the windows don't work, locking doesn;t work, radio doesn't work. Is there an electrical reset! routine perhaps? I intend to sell it for spares or repair but need to get the electrics working first

Answer this question

Jo, Staffordshire

Citroen C4

I purchased the car last week second hand. Yesterday the engine management light came on and I got a message on the dash saying Anti Pollution Faulty, the light has stayed on ever since and the message keeps coming up everytime I start the car up. The car is juddery when it is first started up in the morning but fine once it is driving. No loss of power at all. This morning I was driving to work and the temperature went right up, I got a stop warning light showing. I stopped the car switched off and restarted again and it was fine until I accelerated and the same thing happened again, temp right up and getting a stop warning light. My concern is about the engine management light permanently on and the error message that keeps coming up. Any help or advice would be most appreciated.

Citroen C4

Hi would be appreciated if you can help with this. I recently purchased one of these cars second hand, and at first I did notice a droning noise as if coming from the engine, (although can't exactly pinpoint the location of the noise). The noise is getting much louder and very disturbing when driving. Also when the car engine is switched on, and touching no pedals, the driver seat and steering wheel shudders/shakes and makes a strange acceleration noise and the brakes occasionally squeak when pressed. I am going to get it checked as soon as possible, but would be great if you could tell me what is wrong. Thanks

Citroen C4

My seat belt chimes activate intermittently at any odd time and the only way to stop them is to stop the car, switch off then on again. It doesn't matter whether there`s one or two in the front seats. Releasing the seat belt from the receiver doesn`t stop them either. My service mechanic can`t find any fault, nor a local auto electrician. The Citroen garage just plugged the computer in but it shows 'no fault'. Driving me mad. Any answers please?

Citroen C4

What is approximately the cost of fixing the particulate filter? I was driving in the city centre when smoke started coming up from the front of my car, then I noticed that the car was on fire under the engine. My car is on warranty but the dealer told me that the warranty is not covering this fault and they told me to pay £1000 for this repair, but the next day I made a phone call to them and they told me that now the particulate filter is covered by the warranty but the other part is not and I now have to pay £950! Can anyone explain why?

Andrew Maslin, Essex

Citroen C4

My car has been off the road for a while and my steering felt stiff just before I left it. I didn`t have time before leaving to fix it and now I'm back and now I have a steering fluid leak. I managed to find the fluid level and bought some more LDS liquid and topped it up a bit but could see it's dripping every 10 seconds. Having tried to find out how to fix it, I just cannot see any information about it. Does anybody know if this is a big job to fix? And what could I try before asking the dealer to pick up my car and fixing it? Thank you for any advice!

Citroen C4

Hi, I've noticed that I have oil in the engine coolant and I'm trying to identify the source. I've checked the engine oil and it shows no sign of water contamination. Also, the engine is not overheating and there's no smoke coming out of the exhaust so I'm pretty sure that the problem is not the cylinder head. Does the gearbox have a cooling system that could leak oil into the engine coolant or is the gearbox air cooled? It's a 2009 C4 1.6i 4 speed automatic transmission.

Check in fuse box in glove box, big grey maxi fuse (rest of fuses are minis), almost in middle of fuse box just on top of mini fuse row. According to Citroen you must pull that fuse out for ±10 seconds and put back, then the ecu will be back to factory settings.

It is the fan blower resistor ( also known as hedgehog). Had the same problem a couple of months ago. Fairly easy fix, if you remove the glovebox it's located on the right hand side behind the centre console. Can find the diagrams online. I found a new resistor online for £25.

Citroen C4

(I think I have the right model) I have had this car for 9 days now, since I have had it the centre console has switched off and reset 4 times. I will be returning to the dealer on Weds, but would like to know why this is happening? Is this a common fault? If so, what`s the fix? or have I bought a dud?

Answers

Hi Ashen, get a can of spray, switch cleaner on, put the straw on the can and give the switch a few squirts via the toggle control button, whilst pressing and rotating the buttons etc. You can get it at most good hardware shops or maplin's etc. Common issue with this, cheapest option first, normally works, the cleaner just cleans the switch contact from the inside and simply evaporates away. Worth a try. Andy from Norfolk

Answer this question

Peet, South Africa

Citroen C4

I have a problem with my C4, when I am traveling at speeds between 75km/h and 90km/h and I accelerate or put the engine under power the car starts to shake viciously when I let go of the accelerator the car runs smoothly. I had the rear lower engine mount (back of engine where drive shaft go through) replaced but still the same problem. This only happens when I reach speeds of 75 km/h and above while accelerating with my foot down hard. If I accelerate gradually it is not so bad. But when accelerate suddenly then the car shake badly. Can this be the gearbox mounting or maybe a suspension problem?? I had all the wheels balanced 2 months ago and had the wheel alignment checked. Anyone with a similar problem?? The car runs smoothly at 60km/h and below.

Answer this question

David Stratton, France

Citroen C4

I have a Citroen C4 coupe. The battery was flat first thing in the morning. Bought a new battery and within a week the new battery was flat. Called out my local Citroen garage who said there was a power drain flattening the battery when the car was not in use caused by the computer not shutting down all the electrics, and when sitting in the car with everything switched off, a buzzing noise could be heard. They said that to stop this power drain the computer would need to be unplugged. Citroen say that the unit needs sending to Clarrion to find the problem. The cost of this is prohibitive. Meanwhile the Sat Nav along with all info and stereo are not working. Can anyone come up with a more realistic remedy? The car is a 2007 model. All help will be gratefully received.

david jones, Wrexham

Citroen C4

I have a C4 Cachet (what does that mean?) 1.6 hdi. There is a rattle from the boot area which on closer inspection sounds like it`s either side of the boot in the wheel arch area. Over 30 mph it goes or we just don't hear it. It`s very annoying. The mechanic who did the MOT on it had a quick look and said it`s nothing unsafe hence the MOT pass. I`ve tried everything - spare wheel out, parcel shelf, little gaiter things that cover some arm behind the rear wheels as you look through arch. It has to be something in the wheel arch area behind the boot liner but can`t see anything obvious. Also another little quirk - the panoramic roof blind (manual) only clicks shut at 3 points, leaving one side a bit saggy. I can`t see through the roof due to obstructions or from inside due to awkward. Does anyone else have this and any ideas? New clip etc? Thanks in advance
