Vibrations at speed of 80-100km/h

[BK Lim]

Hi all,

I just gotten my first BMW 318i 2009 LCI, I notice a vibrations from my driver seat whenever I let go the acceleration pedal at the speed of 80-100km/h. Any speed lower or higher 80-100km/h, there's no vibrations at all. Is only at speed of 80-100km/h and is only after I release my acceleration pedal.

All mountings, suspensions changed but this issues still occur.

Any Bros and Sis can advice?

Check your wheel balancing?

Hi TeaazRed. Thanks for your reply.

I've done a high speed balancing together when doing my alignment for the new suspension.

Did you check tyres? How old are they and what model/type of tyres are you using?
