Typical problems I have seen in my short time on X5 World are :

wont start usually down to an injector or injectors 'leaking back' (common problem);
wont start fuel rail pressure sensor;
wont start Cam sensor;
Wont start fuel pumps (any of 3)
Wont start fuel filter problem.

Problems with heater 'plugs'

Problems with aux ventilation (fitted as standard on European Diesel X5)

This is not an exhaustive list, however if anyone without a diesel tries to search for diesel problems you would spend a lot of time filtering them ot from everything else.

Is there a way we can retro link previous Diesel threads to this one now?

Many thanks
