What the convertible roof warning light means. During normal operation, the convertible roof warning light will illuminate when the roof is opening or closing. When this light shuts off, it indicates that everything has been locked down and normal driving can resume. Typically, the system will only warn the driver of a fault during startup.

The immediate issue is this red blinking light when I manually close it as I fear that will drain the battery. The top is definitely secured as I cannot crank it anymore yet it continues to blink red.

It goes like this: when I press the 'open roof' button, the rear shell goes on top of the front shell as it is supposed to, and when it is time for the trunk to open, it does not. I still hear the pump working for another ~5 seconds after which the car gives up and starts flashing red light. It started a few years ago.
Very common problem. Check out the Shipkiller web site I posted above. A BMW dealer will charge you at least $3,000 to replace it and an indy shop probably anywhere from $1,600 to $2,500. DIY and save big bucks, but it will take some skill and determination. Sep 13, 2013. Messages: 12. Likes Received: 1.

Sometimes if a box or something jostles one it will trip the safety so the top won't go down (but will still unlatch for some reason). Just raise both (so the top can't go down) then lower both and try to drop the top again. K.
