my car works fine, all the gauges work fine, every now and than the battery dies if i don't run the car for a while, battery is good bought within the last 2 years and is over sized for the car i just think that when i turn off the key and lock the door it should no longer display my current kilometer count, any idea what the cause could be? oh, and my model is a golf CL turbo diesel, not tdi, in direct injection engine if that helps thank you
