how do I reset the computer on a 200 vw Passat v6 30 v
Disconnecting the battery will reset the computer and the codes. If you have a code reader that can also reset the codes. Otherwise, your local auto parts store will check your codes and reset them as a free service. By the way, my guess is that the ABS sensor is bad. If you want the light to stay off you will have to replace the sensor.
