Mate of mine is selling the 2002 car below with the following problem. Am thinking about buying it - what do suspect the fault / cost of rectifying would be?
"The car has had an infuriating induction problem for about 10 months and it has really worn me down!
At the MOT it was smoking a little (although fine on the emmissions test) so I took it to a specialist who diagnosed and replaced the EGR valve. This stopped the smoking but left the engine a little hesitant, on the same specialist's advice I changed the MAP and MAF sensors. This improved general performance but was still hesitant, back to the specialist.
He then said it was over boosting due to the turbo waste gate mechanism. So, I took the turbo off, cleaned it up (it was full of soot) replaced it. It went like a train after that, very impressive. Unfortunately this only lasted a week, the engine management light came on and it went into limp home mode.
The management light is no longer on and the car drives okay but it is like driving a car with 80bhp not 150bhp. It seems reliable like this, i recently made a 250 mile round trip without problems and it still returned 40+ mpg. But I do have to drive it carefully, no hard acceleration and no high revving etc..."
