I had problem same every one at first but it had changed a other issue after that.
I lives in California and drive 07' 650i CV. Lately, the red light kept blinking sometime either I either hit unlock doors on remote twice (I set unlock 2 doors at once) or left my car on summer sun packing lot. It appeared the fault" CV not lock.." . Usually, I used a tool called Allen wrench in the trunk to slide down (open) the rear window completely. Then pressed the open cv button, the top will open completely and the red light will be gone.
Last week, I had other problem. After I drove mine with CV opened, I parked in my garage for a day. Next day I wanted to close the top and the top only went half way then stopped. I tried to open and close but it just stopped in half way of closing. I ran a test and it appeared the code A6A7 "Saving energy mode in active" This code had never been appeared before.
Does anyone know the code mean and how to reset it?
