Engine Anti Pollution Fault Etc.

[busman]

I recently acquired a Citroen C5 estate on an 02 plate from my step father.It has loads of history.Recently, my step father encountered the "service" light continually on even though he had the car serviced a few weeks earlier.He also had "Air bag faulty" permanently on.Therefore he took the car to the usual garage.It was put on the diagnostic machine and showed no faults.He was told by the mechanic that the computer starts playing up after 10 years or so and that the lights it lights up are nothing to be worried about.I have just had the "Engine anti pollution fault" message come up on the dashboard computer and also the engine management light is lit up in amber.Is this another computer blip to be ignored or does it mean something more serious like a filter needs cleaning, or a sensor needs resetting? Any help and how i can do it myself rather than take it to a garage will be helpful.And can I reset the airbag fault and the service fault??

Unfortunately your car predates the universal £30 diagnostic boxes if it is diesel. If it's petrol, then it should work with the standard EOBD II boxes you can get on eBay, but check carefully first.

 

You'll need to take it to a good Citroen independent garage, and get the fault codes read on the diagnostic, if it's diesel. Which "usual garage" was it taken to?

 

Then you'll need to sort out the problems.

 

Driver air bag faults can be the COM 2000 unit. This needs to be coded into the car, so isn't, AUIU, a DIY. It's about £400.

 

I would advice you to simply get rid of the car if you are not going to get the problems sorted, especially if it's a 2.2, as the engine will eventually go into limp mode.

 

You'll need to post more info for sensible advice. What engine type, and gearbox fitted. Measure the battery and make sure it is not low, as this can lead to spurious warnings.

 

Also post a rough location of you want some advice for sensible places to get it fixed.
