Hi, I'm hoping someone can really help me out,
as I was driving my car the other day I started to notice a small judder as I accelerated. After a few miles I lost turbo and the car seemed to go into a limp mode, but with no engine management light illuminated. As I now start the car from cold it ticks over very lumpy and also makes a struggling sound whilst turning over.
After scanning various different web sites and speaking to my local garage I came to the conclusion that it was possibly a swirl flap problem! The mechanic removed the inlet manifold to find one of the flaps had broken off and was resting against a valve, and one was hanging ready to fall off.
He replaced the manifold with a brand new genuine one but it hasn't seemed to cure it!
I've just driven it home from the garage and have noticed that when I dip the clutch and come to a stop, the MPG dial moves up, surely if the clutch is down and the engine is not revving, it should be still?
My Mechanic now seems to think that the swirl flap that fell of may of damaged a valve, but wanted to get some advice before we take it all to bits,!
Really hope some can help
Thanks for reading
P.S My car is a 320cd M-Sport coupe 04 reg
