Bit of a weird one this so looking for some help, randomly the roof on my 2003 z4 has decided that it will only operate when the engine is off, when the engine is running it won't work at all, nothing, no lights when roof buttons are pressed etc. turn engine off and it works fine. Any ideas??
Z4 hood will operate with engine off but not with engine on?
