Hi people can someone help me with this one please!
About 2 months ago I noticed when turning my lights of and removing the ignition key the lights on warning buzzer sounded despite the fact that I had turned the lights off. I noticed that the dash and control panel backlighting was staying on faintly (at the same brightness that you see when driving with lights off). Also number plate light stayed on.
Then the problem went away and so did my worries about it.
Then it came back but only when I locked the car on central looking (remote with BMW alarm arming) BUT not when I locked it using the key in the door.
In doing some half arsed diagnostic work I disconnected the tailgate locking motor (thinking it was the number plate light connection) and the problem disappeared for two months. With the tailgate lock disconnected I was even able to lock it on remote central locking with no probs.
I believed that the problem was alarm related and didn't think much about it untill.....
Its now happening again even without locking it. To summarise: Stop engine, lights switch to off position, remove key and dash backlighting and number plate light stays on accompanied by 'lights on warning reminder buzzer thing'.
Seems to me theres and issue with the normal interior 'daytime driving dash lights' staying on and not isolating themselves from a power feed.
Anyone had this issue, or perhaps know where I should start looking??
I hate electrical problems!!
