With a Vag-Com.
Except, be careful about scanning the Airbag module.
Battery light signifies a fault with the alternator. Check the accessory belt?
so i was driving my 02 jetta 1.8t, car had no lights on th dash whatsoever. I hit a pothole with the front passenger tire a few minutes later i noticed my battery light came on, about 20 minutes later driving home after a short stop i realize my ABS and Tranction control lights simultaneously coming on then going out randomly stayed on now, and also my airbag light has just come on help car was mint before all this
yeah it was weird idk why allll the lights on my dash would come on slowly one at a time, belt seemed fine not loose or anything..going to take it for a spin in the morning and see if they are still there and how it drives then depending ill bring it to school and scan it and try and fix this Shhhhhhiiiiii***
