Hi, I'm driving E90 320i lci. Whenever from stationary during d mode when I press hard till rpm over 2k, I notice a short high pitch hoooooo sound coming out. I've also tried ds mode and the sound come only at m1 when rpm over 2k. The rest m2 to m6 no sound and smooth. I've sent it to the east coast centre and was informed is normal. This is my 1st time driving BMW, previously merc and Audi don't have this type of sound. Anybody here having this issue?
