Diagnosing convertible top Mercedes-Benz SL500 model R129. In this video, I am reading codes from pin 10, which is for the Roadster Soft Top Module Model R129. You must read all codes on the module twice to be able to clear the codes. Please share in the comment section what code you have on your Mercedes convertible top, and I will share my experience repairing that code; thanks a bunch.
