I bought my Z3 approx 1 week ago.........started fine from cold but when warm...it would crank but not fire.
I also lost the engine intermittently and particularly if i hit a bump.
Engine now won't start at all and there is no fuel coming through......it as if it is immobilised..........
Didn't have any problems when tested with purchaser.
Has 49,000 miles on clock and otherwise is immaculate.
