The ABS trouble codes on a VW can be erased by cutting power to the ECU. The easiest way to do this is by disconnecting the battery. While the codes will be erased, if there is a legitimate problem, they will come back. Ultimately, you will need to get the problem fixed. However, erasing the codes takes just a few minutes.
Loosen the retaining nut on the cable that runs to the VW's negative battery terminal.
Slide the cable clamp off the negative battery terminal.
Wait one to two minutes. This will reset the ECU and begin the process of erasing the trouble codes.
Reconnect the negative cable and drive the VW for a few days, traveling roughly 100 miles. The ECU and the trouble codes for the ABS light should be cleared and reset.
