In a year the mechanics couldn't figure out why the battery kept getting drained even after replacing 2 parts hooked into the electrical system, at the cost of $1,539.00, kept happening (found out almost a year later there were 7 broken wires and the blue tooth system was always in the on position); nor could they figure out that the reason I had to keep refilling the antifreeze every 3-4 weeks was because it was draining into the head gasket. Once I sell this vehicle I will never own another BMW; not worth the price.
