Not sure if this is the correct place to post, so will move if required.
I have a 2003 325ci M Sport Convertible.
I have 2 issues so far:
1. When I open and close the windows the lights on the radio and dash sometimes dim. You can tell alot more when looking at an amber light in the interior i.e. the one near the auto hear shifter.
2. The car slightly wobbles when idle. If I pull a window up or down, the rev needle moves down and the car shakes a little. Not sure if both of these are related or if they are a seperate issue.
Has anyone come across this and if so what do I need to do to resolve.
Many thanks in advance.
