In this video we'll show you how to diagnose and replace a Mercedes rear ABS sensor. We're showing you on a 2005 E-Class Wagon, and other models of Mercedes are similar. The abs sensor connects to the hub and reads a rotating magnetic disc on the axle that informs the car's computers about the wheel speed. This is referenced by a lot of systems on the car. When it fails, you will receive multiple codes and the car may even enter limp mode with the transmission. We cover the steps to diagnose the codes, remove the failed sensor and replace with a new sensor. These are the part numbers for the ABS sensor on the 2005 E-Class: Mercedes A 211 540 30 17 Bosch 986 594 563 If you have a different Mercedes, be sure to research the part number for your model.
