Don't Swap Sensors for Volkswagen
This bulletin applies to 2012-2015 Volkswagen Passat, Jetta, Beetle, Golf GTI and Tiguan. The anti-brake system/tire pressure monitoring system (ABS/TPMS) light may be on due to wheel speed sensor fault as a result of the front wheel bearing/wheel speed sensor swapping.
This can be due to the encoder ring being ground down on the wheel bearing hub unit, resulting in a damaged part. Damage can occur from swapping the speed sensors left-to-right or right-to-left during diagnosis. Do not swap sensors from side to side.
Example of speed sensor interference.
