My battery on the key fob is fine. I checked it on one of those little key fob battery testers and it checked. Looked on all data and found test procedures but I need to hook up a scan tool. I've tried to scan the VW before but I don't have some code i'm supposed to have and can only get via dealer. Any one know of any tests I can do with a dmm or know of any common problems with the keyless system going out??? 2003 VW vr6.
