Mercedes C300 4Matic Engine light off. The diagnostic tool showed P052E error, which seems like a common problem with MB C300 models built from 2015. Is there a manufacturer recall for this issue? This warning came a few weeks ago and disappeared by itself shortly. It came again.

Engine code P052E has come on at 60k miles. After researching the problems this is a very common problem with the 2016 c300 that mercedes refuses to address. To add insult to injury the part needed to be replaced is a sensor worth 100 dollars but mercedes charges over $2500 because you need specialty tools to get to it. This is a very common problem with owners around 40-80k miles and has no cause other than faulty parts on Mercedes end.

P052E - PCV Regulator Valve Performance: Actuator Stuck P06DA - Engine Oil Pressure Control Circuit/Open no sub type information My understanding is these are common issues and Mercedes and anyone who works on them know it is a common issue for all lines. I also have a broken sunroof that seems to be common on all lines. There are some recalls out for the sunroof but not for the C-Class C300, although all of the videos I have found match the same issues that were recalled on other models. The dealer confirmed these are known issues.
