I have a 2009 E89 Z4 sDrive30i with the N52B30 engine. I am experiencing an unstable RPM upon cold start every morning.
It seems to be bouncing around for 2 to 3 seconds upon cold start and stabilises without any issue after that.
It only happens during cold start for the 1st time everyday...
Hello to fellow members, I have a 2009 BMW E89 Z4 sDrive30i.
I have an issue when opening the hard top roof. When the back piece comes on to the top piece there seems to be a loud thud and looks quite rough. Has anyone faced this issue and what could most likely be the issue?
Thanks in...
