Hi Nick,
I know your problem, we talked at Le Mans and BTW it was great to meet you in person. I'll try to google up something in the German language part of the web, however, I need some information:
1. Where exactly is your car? I recall it was Frankfurt? Do you have an adress with street, no, postal code and the usual stuff?
2. I need details about the car. What make, year, which engine, transmission, best would probably be the manufactorers vehicle identification no - I think it has 7 digits.
3. What exactly do you think is the problem with the engine?
Cheers
Werner
