C350E P1D02 - P052E

[NicolaiHB]

Had my car for Service today, and also to check the engine light i got. i Have a C350E late 2016, and it came back with the error P1D02 with and extra P052E. The Message i got from the dealer was ventilation valve for crankcase short circuit to positive. Permanent after clearing codes. Positive crankcase ventilation regulator performance. Stuck - Permanent. Any ideas?

Sincerely

Nicolai H

Hi Nicolai, I've got the same code as your first one. Have you managed to fix it? What was it exactly and how much have you paid? Thank you

Did the dealer not tell you the course of action to resolve the issue?

There is a breather pipe that fails that needs replacing. Common issue.
