Hey Kippawar, an Autel code scanner can help with your problem. The one I got, Autel DiagLink can do the job of resetting those codes. However, if there is an actual underlying problem, your car will throw that code again. In the end, I had to replace the transmission conductor plate, as the speed sensor was failing. If you get the DiagLink unit, during setup you will be able to download various manufacturer appropriate software add-ons. Get the one for Benz. It was only about $10 for the download. Good luck. Let us know how it goes.
