just bought a 2000 vr6 and the battery was disconnected when i bought it. after driving it 50 miles, i parked it and let it run for 5 minutes, and a check engine code came on. called dealer, they said it needs to be reprogramed with vag com after the battery is disconnected. located a guy in my area with a vag com set up, and he says he knows nothing about reprogramming, just running codes.
my car runs rough at idle, and thats what my haynes manual says to expect after a battery disconnect. anyone know what/how to reprogram after a battery disconnect? 2000 Jetta GLS VR6.
