BMW e89 z4 Roof Stuck Close or Open Repair Troubleshooting DIY Repair Guide
There was significant effort involved in identifying the cause of the malfunctioning BMW Z4 roof, not because it was a difficult issue to diagnose, but rather due to the challenge of accessing the roof when the roof is stuck closed or open and you need manually open it, to prevent this from happening you need to do this for the sake of yourself because if the convertible top is stuck close or open, it’s no fun. But if that happens, check the pdf file: Repair Manual BMW E89 z4 (N54 engine) -
The PDF File is over 200Mb. Don’t ask me where to find a specific section.
the BMW z4 roof maintenance should have a section on how to or when to replace the microswitch wires and the exact procedure.
My suggestion will be after 10 years or 100k mi. in my case the car is black and it digests lots of heat in the summer, and it transfers into the wire shell, and it starts disintegrating much faster. The BMW e89 Z4 is an amazing convertible but the convertible top is a piece of technology and it’s a weak point in this car.
