Consumer Description

Most M274 engines have P06DA00 fault code internally. Harness for oil pressure regulating solenoid valve is short/open inside the engine oil pan. It can cause excessive oil pressure and premature oil pump failure. As the broken wire is sunken in the engine oil, I worry if it can cause fire. If the oil pump fair during driving prematurely, engine can be stalled. Mercedes-Benz knew the issue but they decided to ignore it.
