My q7 3.0 tdi.........is draining the battery,its ok if i go to it 12/13 hours later but after that its flat !
Ive been told by audi i can charge it via points under the bonnet,which im doing now.........i have vcds how can i check if something is draining it or the batterys shot?
Audi replaced it in may 2011 so its not 2 years old yet
Like i said i have vcds,but dont know how test whats draining it etc........please help.
