VW ABS sensor. The ABS sensor is mounted to the passenger side front spindle assembly. Without a properly functioning sensor your ABS computer will not work properly. This can lead to some dangerous situations in the rain and snow, especially if you've never driven without ABS. Replace your faulty ABS sensor with this original equipment quality part.
The VW ABS sensor is a critical component to your vehicles driving system. If your Volkswagen has ESP, the sensors relay information to the computer so that it can make adjustments according to the conditions your are driving in. If you want to know exactly what is wrong with your ABS system without going to the dealer you need a VAG-COM scan tool to read the fault codes and start diagnosing from there. This ABS sensor on late model Volkswagens is triggered by the ring around the wheel hub assembly shown below.
