Mercedes Fault Code P06DA00
2:41
$24,000 for a $150 part?! This 2020 Mercedes E63 AMG Wagon with just over 30,000 miles through fault code P06DA00 – oil pump control valve electrical fault. To replace it, the entire M177 engine has to come out, the transmission dropped, and the oil pan removed just to access the valve and the harness. The dealer quoted $24k just for this repair . On this generation, the issue sets a check engine light, but on many other Mercedes engines the same fault code shows up only in the system with no CE
