Have a c250 that had a C2552 code. Went out yesterday and installed new Cyan IU and also had to replace the drive unit for the I/U's because the cyan IU had locked up and stripped a gear. Customer called this morning with C2552 code again? They opened and closed the door and it is running again. Any suggestions? It is a way out of town account so wanting to get info before going back.
Thanks,
