CommentLimp home mode on.
BMW 3 Series 2007 320i Sedan 142000 miles
Vehicle was standing for about 3 years after it was knocked on the left side front fender and bonnet. It was starting and running but would suddenly cut out and I it always take two cranks to start. About a week ago, I left it idling then it suddenly cut out and when I started it again it went into limp mode with wipers on constantly plus dsc and abs warning lights on cluster. Fuses are good and there's power to the DME. please assist been battling. Thanks
