Maybe I'm just too optimistic - but I was certainly given this impression by somebody I can't remember who that it could happen. There is a procedure in place to request a contribution from Citroen how likely they are to pay out - I don't know. | ||||

Mine started to get the warning but nothing happened also, but now the suspension does deflate, but as soon as the garage clears the fault code the compressor reinflates and suspension returns to normal but once you have stopped and restart the engine, the warning light goes on and suspension has dropped, the mechanic is again able to reset code (suspension relay!!!) suspension goes up again!!! I will speak to the garage this morning to see if they have been able to get any help from Citroen. |

My newly acquired 57 reg has now been in main dealer workshop for 2 days due to suspension problem on only 2nd day of use. Deflated and could not get to reinflate by using buttons inside boot. Service light on. Interestingly no fault or speed limitation message displayed. Drove a few miles slowly then tried again- no luck. Parked overnight. Still deflated. Drove 1/2 mile slowly. Parked and reached for mobile to ring recovery. Instantly compressor burst into life and reinflated so was able to drive the 18 miles to dealer without problems. Have a C1 courtesy car (!) and awaiting developments. |

Unfortunately that's the nature of 'intermittent' faults, until they fully develop it's hard to say exactly what the issue is but at the moment there seems to be more air bag failures than ECU failures looking at what others have posted |

Not so fast. They went to move the car this morning ready for collection and one side of the suspension has failed. Now we are back to square one and we have to wait for another part. I notice that other posters have mentioned the "ECU" is this something I should get them to look at or is it best to leave them to it? Presumably I won't have to pay for the part that didn't work. I'm also hoping I won't have to pay twice for the labour - what do you think? John. |

I have continued using my car for short journeys while waiting for parts (air bags) but I am beginning to wonder whether it is the air bags or not... The car doesn't deflate overnight, if I park it inflated, it will stay like that till morning. It has completely deflated twice now, and both times the car was fully loaded. Every other time I have used it with only 2 or three people in the car, it's been absolutley fine..?? Perhaps it is the airbags that deflate over a certain weight, but like I said it's fine overnight... Infact the two times it was deflated and I parked like that, by the morning it had returned to normal. I guess I'll have to wait for the citroen verdict... I'll keep you updated. |

Hello Everyone, I am new here, have just registered after reading through the threads regarding my air suspension problem, well known to many of you. I have a C4GP Excl. from October 2006 with 32,000 miles on the clock. Yesterday morning I found it with deflated rear suspension. It lowered its boot symmetrically. When I opened the car by the key it inflated all right and had no error message on the display. I drove some 30 miles without problems or warning messages. However, by this morning it deflated again. I tried the manual inflate/deflate system in the boot and it works ok, there is still no error message. My question is: As the deflation is symmetrical, i.e. it affects both sides, I wonder if it really is a faulty air spring. Can they both die simultaneously? Or is it the ECU or the compressor (which seems to be working). If it is a faulty air spring the car should stand with one corner lower than the other, shouldn't it? Of course I will call my local dealer first thing tomorrow but I would like to know what you think. Any feedback would be appreciated. Kind regards and my greetings from Hungary  Zsolt |

Unless there is some isolation between the two sides, for instance, separate piping or non-return valves, pressure loss on one airbag will equalise with the other, and both sides will go down together There are several threads on this issue, and, as far as I know, no-one has reported only one side going down. I had the suspension warning on mine, but no other symptoms. The ECU was replaced under warranty. |

What you are saying seems logical, but Jamijulius reported that his car deflated on one side only: - Click Here - And jls483 had the same issue: - Click Here - -- this is what made me believe that the air springs are separated somehow. |

Hi fenney1, my suspension air bag was replaced two days ago (only the left side one, because I did not feel like paying twice as much for an unexpected defect - I am now saving up for the replacement of the other one before summer). Mine also had tiny holes in it and was visibly cracking at the area where the rubber is folding backwards when the suspension is moving up and down. Unfortunately this part gets a lot of road dust and grime, too, I think this does not help extend its working life either. I asked the mechanic to clean both the new and the old one and lubricate them with silicone, maybe this will help keep them healthy. Like I said earlier, mine has some 32,000 miles on the clock. By the way, I bought the part from Citroen Hungary for the standard list price and had it installed by an independent Citroen garage for about one-third the price of the part. I did not have to pay for diagnostics because the small garage did that for me as part of the process (I took the car to them saying it deflates overnight and if they wanted to repair it they obviously needed to find out what was wrong. I cannot see the point in asking money for "diagnostics", that is part of the repair job, ain't it?). The official Citroen dealer where I bought the part would have charged twice as much for labour. The small garage could not get hold of the part because there was a shortage, but the big dealership could order one from Vienna by claiming that my car was immobile as a result of the defect. It arrived overnight and did not cost a penny extra. Excellent service. Hope this helps, Zsolt |

In case anyone missed the post earlier I just want to reconfirm the airbag part numbers: The part number for the suspension bags was 5102R8
However, they have just been superseded with part number 5102GN Time to change one at a dealer, around 30 minutes to 1 hour, so if you get it done at a local dealer you will get a 12 month warranty on the parts and it should cost around £100-£130 for one to be changed including labour Change instructions and parts list diagrams are in downloads: - Click Here - |

Yes, C6 Dave, I should have credited you for this info in my earlier post, I was very grateful for this piece of info. In Hungary the dealer was very decent, a few months ago this part cost HUF 45,000 (approx. GBP 139) but now it is only HUF 18,000 (approx GBP 56). They did not try to rip me off with the older part number but it was still nice to be prepared Thanks again! Zsolt |

...although it takes half an hour to an hour to change these things the Citroen guide that my dealer was using said 1.3. Although I was lucky enough to discover that it also reckons 1.3 hours to change two! So I was given the choice of £170 to change one or £240 for both. So whether you fix something that ain't broke is up to you. I felt that as these things seem to have a life of about three years there was a good chance the second was about to go. So I spent £240 now rather than £170 now and £170 next week. John. |

I am sorry to hear about your ordeal, John. On some C4GP's the electronic control unit had to be replaced so maybe yours is faulty, too. Or there may be an installation problem -- maybe a leakage in the piping system? | ||||

Mine has also starting doing the deflating thing over the past couple of weeks and my dealer won't look at it until it refuses to re-inflate. However I'm thinking that it can't be a leak in the system as surely it would slowly deflate EVERY time the car is left unattended and not just occasionally? I have only once seen it actually deflate in front of my eyes and it was a rapid deflate with an audible hissing noise. To me this suggests if the fault is intermittent it is more likely to be an ECU problem (or whatever it is that controls the compressor)...... |
