Can anyone help? I've recently acquired a 2004 407 2.2 petrol which shows up a 'depollution fault' which has been confirmed by an electronic diagnostics check.
The diagnostics revealed an error with the map sensor but the problem is random being activated by temperature (external not engine), acceleration and bumpy ground. Sometimes the error stays on the OBC othertimes it clears itself.
I have just had a new map sensor fitted but the problem has returned immediately. Does anyone have any clues?
I'm led to believe that this is a common problem on diesels and an expensive one to repair but no-one seems to have encountered the problem with a petrol engined 407. Asides from the warning light and being a little sluggish pulling off, the car runs fine.
