Hi, I have a e92 335i abot 90000km on it. Whenever cold start there's metal clicking sound from engine for 10sec, I guess that's normal, but when I accelerate the car from 0km/h to around 30km/h, at first there's exhaust sound but suddenly it becomes quiet seems like turbo kicks in? But when exhaust quiets down it follows with a shake and metal sapping / clicking noise, it's pretty loud, specially when I just start driving the car in the morning when it not all warmed up, the noise not so obivous when car warmed up but can still hear it. And when driving at low speed(under 40km) when car goes over bumpy road I can hear noise very similar to the metal noise above but not as loud. Could it be suspension or differential ? Anyone has the same prob? Thx so much!

The noise just single one time thing at 30km. When I slow the car down to 30 thers no noise. When I re accelerate the car pass 30 it snapping/clicking noise again once, thx for any help, the noise last abot 0.5sec only,
