2006 BMW 650i Q&A
2006 BMW 650i Question: top and trunk will not open
Every two months the top won't go up and the trunk will not open. The bmw dealer "reset" it once and it was fine. Now it is not. - Visitor
Is valet mode on? Try a battery power reset, remove the negative battery terminal for 10mins, refit, tighten and retest - Chow
As a result I get the error when driving and know the car doors will not lock as well as opening the trunk.
