I have a 51 reg 318i touring that has suffered all the usual known faults but with the exception of the brake lights.
The brake lights have a mind of their own and are either always on or, working normally. Everything has been tried including switch replacement. Incidentally, the climate control stopped blowing air recently-this has strangely started working again.
I have noticed occasionally slight hesitation sometimes on take up below 2000rpm-the car is sluggish and lacks any real power-otherwise, when operating normally, seems very responsive and full of power and was wondering if this is an electrical voltage/charging problem?
