I know petrol cars, I know little about diesels, so if I were in your shoes podge I would be taking my car to a diesel specialist. There must be a diesel man somewhere that you can at least talk to concerning your problem. Even if its just to get his opinion on your problem before you have to admit defeat and take it to him to have a look at.

I hate to say it but I bet he'd be able to solve your problem alot sooner than us petrolheads could!

Forget about it being a beemer, its a diesel truck/lorry/tractor-whatever, and thats all you need to know right now. Turbo, non-turbo, a diesel engine is a diesel engine.

Just my tuppence worth. Good luck
