    Hi i just bought my first bmw (1996 e36 318i). I know its slow/weak but when i try to accelerate from 0km/h it feels like its shifting between power and no power. I don't have an asc button so im assuming i don't have that feature. Anybody have any idea of the cause??

    Hello, My car is a 51 plate 330D and I have the dreaded 3 lights on the dash which I know indicates there is an issue with the ABS system and more specifically I believe it is the ABS ecu, as the error code is 5DF5 (internal ecu fault). I have removed from a 2002 320D the complete ABS unit...

    Was driving @ approx 60mph a few weeks ago - the transmission on my 2000 E39 523i Auto switched into failsafe mode quite randomly. The car stayed in what felt like 3rd or 4th gear and would not shift up or down. The engine would have to be revved high to pull away from a standing start at...
