Z4 e89, was brave and bangers everything about, pressed the roof off button and after a lot of woring and hesitation off it went. Managed to close and lights are out at the moment! Next time I try that I'll be at bmw garage, got thoughts on dodgy motor! Any idea on replacement cost ???Sorry thought you had E85 Z4 that has the parcel shelf knobs in the boot. What year is your car, the motor is under the boot floor looking at your photo. Not sure where any of the micro switches are on these. No doubt someone will be along to answer soon.
Just noticed you list yours as a 2.8 Z3 in your ID are we looking at a Z3 or Z4?
Plugging in diagnostics that will read the roof module should tell you whats not working, BMW Scanner 1.4 should read the module ok also BMW INPA.
