  1. 330ci Auto - Knock when shifting between Drive and Reverse

    General E46 Forum
    Hi guys.. Got a big knock sound (and jolt felt) when shifting from Drive into Reverse and vice versa. Just had the Diff mount changed which was on its way out but the issue remains unchanged. Got told there is a bit of backlash in the diff and an oil change might help. Any experience of this...

    General E46 Forum
    Hi, Last week my '03 318i started to hesitate while accelerating, but after the RPM's got higher, it would go like normal.
