2016 MERCEDES-BENZ C300 Complaints

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.

Engine light on smells gas constantly tried to change oil that did not work light came back on

i have been noticing a hissing sound coming from the brake paddle for almost 3 weeks. upon some online research i found out it could be a brake booster and there was a recall for the same car brand due to issues with brake booster in past but not included year 2016. vehicle not inspected yet.

CRANKCASE VENTILATION- code: P052E came up and I had just bought from the dealership with 87k miles

Started smelling gas then check engine light came on took it to mercedes they did diagnostic which said low boost and that I needed to replace the turbocharger at a cost of over $7000

My check engine light popped on with code p052E for the Positive Crankcase Ventilation Regulator Valve Performance.

Check engine light comes up. The crankcase ventilation has to be replaced. This is a well known defect in design by Mercedes Benz and there are hundreds of people who have had to replaced the crank case costing thousands of dollar to only have it happen again due to its faulty design. It’s well documented all over the Internet.

It is such a common issue reported by many 2016 c300 owner who experienced error code p052e bad Pve valve. My car only has 40,000 miles. I think the manufacture should be responsible for a recall. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My sunroof shade is stuck open which makes my extremely hot . I’ve been burned twice by my seat . My car has 93,000 miles .

The code P052E reads at only 49.000 miles....Mercedes wants $3000.00 to repait ir (replace PCV valve ). Car runs and drives normally....its probably a faulty sensor. I have seen a lot of posts with owners havins same issue.
