I have a 3 series 3 litre convertible 57 plate. I had items in the boot when closing the roof which got trapped the dash board management warning now shows a malfunction and nothing happens my handbook shows this is the roof mechanism malfunction warning light
I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.
what has most likely happened is that one of the roof's sensors that informs it of position and closing progress has likely been damaged and now, as the required sensor signal is not present, the roof will not open
to verify where the issue lies, you will need to have the fault logs read from the car using a BMW scan tool. There is no way to manually diagnose this roof, it was designed needing 100% computer diagnostics. There are too many sensors and dependencies to check manually.
