I have a 2000 CLK-320 with 150k miles. One day it went into "limp mode". I put my scanner on it and got p0715. I checked the transmission fluid level and it was ok. I replaced the 13 pin connector adapter plug and O rings. Still got p0715. I replaced the automatic transmission conductor plate. I still get p0715. What should I do next?
Is it possible that it is fixed, but my scanner won't clear the code, releasing the car from "limp mode"?
