Citroen C4

Hello, recently I bought second-hand C4 and it works fine EXCEPT now I have a problem with fuel lamp. So the other day the fuel lamp went on I went to the gas station got some fuel- the lamp was still on! So I went again -got some fuel again and the lamp is still on and kilometers are getting lower and lower. Latter when I turned on the radio I heard the beeping sound sounding as a warning- it does not shuts down. Now with the fuel lamp on and no possibility to listen to the music I am asking for help- if anyone can tell me whats wrong with my car? Is this a big problem? Do I need to take it to get repaired? I do not have a guarantee and I am hoping it is not serious.. Thank you, Anja

Pam, Australia

Citroen C4

After driving for about 20 minutes in warm weather - 24C and above - (no problem in winter, but it happened last summer), even on warm evenings my 2006 C4 1.6 auto with less than 60,000 km on the clock does a very audible and frightening 'thunk', a kind of jerk, when stopping at traffic lights. I know when this is going to happen as the engine goes very quiet as I am almost stopped and then comes the 'bang' about 10 seconds later. I have been told that this may be that the car thinks it has stopped as it transitions from 2nd gear to 1st. I try very hard to drive slowly when I come to traffic lights to avoid stopping and getting the bone crushing judder. As I have just spent $2,500 to have a steering wheel problem fixed, (went suddenly stiff while driving and had to force steering wheel just to pull over to side of road. Had some near-misses with that - apparently computer problem and ok now), I would like to avoid another hefty bill. I also have an 'anti-pollution' light and 'service' light regularly come on and off, but I just ignore them. Servicing the car does not fix this and the mechanics have no idea why it happens. Does anyone have any idea what may be wrong?

Citroen C4

Hi, could anyone give me any advice? I am at my wits end with my Citroen C4 2006. I have had nothing but trouble since May with various issues. I've just got my car back today after it being at the mechanics for a month and now I have another problem. Once starting my car my steering is locking, if the car starts to drive then the steering will come back as normal. I'm so worried in case the steering locks when I am driving the car as it is very difficult for me to even turn it slightly. Does anyone have any idea what this could be? Thank you in advance.

Citroen C4

I currently have some problems with car Citroen C4 1.6 HDi (diesel) (1) My radiator/engine cooling fan working intermittently (2) engine temperature gauge would suddenly go up from three bars all the way up and flashes STOP with three beeps (3) When engine starts gets a message that "Risk of Filter blocking" (I do motorway driving so DPF should not be an issue?) (4) I have pool of diesel around injectors. (5) my service light is constantly on even though car as been serviced. I know this is a lot for one car. I have been to the garage they don't know what's wrong because physically car not over heating (no smoke/vapour from engine) and computer isn't reporting anything (I wonder the types of mechanic these days who can't fix a car if computer is not telling with any codes). Two of the injectors have been replaced. Temperature sensor changed twice. Fan resistor changed. I was told may be electrical issue well known of French cars. Any help?

How do I reset kmh to mph? What do I press to set this? Cheers

Answers

Press the menu button use the up down or side to side arrows when in the menu function. until you see litre or mpg flashing on the screen. When on MPG press the menu button and this will put the car back to MPH. Sounds silly to change the litre or mpg, but this changes between KPH and MPH. Lots of info on how to do this on net. You will need to reset other things on the menu as well as the above, like language etc. hope this helps. Ray Edge from Shropshire

Answer this question

Len, South Africa

Citroen C4

My 2007 C4 1.6i petrol suddenly won`t start. Monday I went to work and back and Tuesday morning I could not start it. Battery is fully charged (1 year old). When turning the key to start, the engine is turning but won`t start. I tried to jump start it with my wife's car but the same story. It won`t even do a 'running' start off if towed. Central locking is working and headlights are bright. The central display on top of the dashboard (grey area) where speed, etc is displayed goes totally blank after the car is switched on. I replaced the battery terminals but no luck. This is the first time this happened since I cleaned the battery and terminals that were badly corroded a couple of months ago. One thing though is after the cleaning the language turned to French and no menu functions work to reset language, time, etc since then. Now it displays an INFO message"MODE ECONOMIE ACTIF '. I stay on a smallholding and am stranded as the closest Auto shop is about 15KM away. Any one with a suggestion?

Hi I get a squeaky noise every time I take foot off accelarator but only last for 10min do you know what is causing this as it is so annoying thank you

Answers

Had this problem myself, It squeaks like an old rusty spring or two bits of metal rubbing together. It normally lasts until the car gets warm (well mine did). The problem is the flexible joint between the CAT and the rest of the exhaust, if worn it moves when the engine rocks when being revved when the engine is cold. It needs a new seal fitted they only cost four or five pounds to purchase, but the fitting is not easy, you need a ramp and is still awkward. You need a mechanic or an exhaust specialist to change it. Probably cost about an hours labour. This fixed my problem on a 2006 C4 1600 petrol. Ray Edge from Shropshire

I had same problem, turned out to be a common fault with Solenoid cap blowing the starter fuse in position 8 under the bonnet. Turns out you can't replace just that so had to pay for a new starter motor at a cost of £150, however I have the continuing saga of Polish language on the displays & KM rather than MPH which is apparently a radio fault!

My Citroen will randomly cut out when I come to a stop street or robot. It will start normally quite easily but wont idle very well and need to rev it a little. I have cleaned the mass air flow sensor. The car other than that runs very well and fuel consumption is excellent. It is an intermittent fault. I ran a diagnostics and came up with a P0106 power train fault. If you read on line it is not very specific and I don't want to replace half the motor. Please advise. Thanks in advance.

My car currently vibrates at 70mph and vibrates violently when braking at around this speed. My car is new from september 2013 and according to the garage its brake pads and discs had warped and was classed as out of warranty on this occasion as the car was 10 month old. Problem was fixed or so i thought. My local dealership now has the car back and have had it three days and have had no resolution to the problem. Has anyone else had this problem and what could be a fix for it as my local dealership are completely stumped.

Citroen C4

Hi, my 2011 Citroen e HDI 1.6 Diesel with the electronic gearbox and 85000kms on the clock is really great to drive except when in a slow line of traffic (really slow/stop start sort of thing) the vehicle has an abrupt action when you take your foot off of the accelerator to slow down. Feels like load suddenly being released from the clutch plate. It is very annoying especially when in a really slow line of traffic. Also noticeable when driving down a mountain road and having to take foot off of accelerator to control speed. Is this normal as I am sure it did not do it until the last few months?

Answers

Hi, I have a 2009 16. HDi, EGS, which sometimes exhibits similar jerkiness. It seems to be a 'learned' behaviour in the throttle position sensor. I tried a reset procedure which I use with my auto BMW, and this seems to resolve the issue for me. Procedure is as follows: 1. Insert key and turn it until all the dashboard lights are on. Keep your foot off the brake, so the car won't start. 2. With the key in this position, press the accelerator fully to the floor, and hold it there for 30 seconds. 3. Release the accelerator, and leave it for a further 30 seconds. 4. Switch off the car, and leave for a few minutes for the reset to complete. Please let me know in this thread if this resolves your issue. Niall from Ireland
