I was taking off on gravel and all the lights came on. Checked and it says left front wheel sensor, checked speeds and all move except it. I removed it and cleaned inside the hole with no success. Can you get me the right part number as it has to be a Benz otherwise these cars act funny with aftermarket stuff.

If you are not seeing the speed on that sensor, check the wiring first. The easiest way would be to unplug the sensor on the other side then run jumper wires from the good sensor over to the "bad" sensor. If you now have a signal, it's a bad sensor, if you don't have a signal, you have a wiring issue. Both fronts are the same, as are both rear sensors.
The fronts are part # 2219055700 if it's the base model.

If it's a 4matic the sensors are different and depend on the build date.
Before 9-6-2010 it uses #2215401417 if the build date is after 9-7-2010 it's #2219055800
