Check engine light for P052E which has been coming and going off for years now. Now the check engine light is there permanently. I spoke to Mercedes Benz customer service and requested for them to fix the problem now that the light is on permanently but they refuse to fix it because the car has 222,000 miles on it. This should be a recall from the manufacturer not an extended warranty coverage. The Mercedes dealer in Valencia California told me they now only do a software update and put a plug cap on the sensor and want to charge me $850 even though this should be a recall

What owners say
Cabin smells heavily like fuel and has a check engine light possibly a fuel leak
Check engine light on. Test results: Positive Crankcase Ventilation Regulator Valve Performance CODE : P052E
Car check engine light came on with only 62,000 miles. Diagnosed as code P052E, the issue is the positive crankcase ventilation valve being faulty. Regular oil changes and maintenance was done. I see multiple complaints with this issue, why is this not recalled? It is very expensive to have fixed.
My engine light keeps coming on and off on my 2017 C300 4matic coupe. I got the problem diagnosed in March 2023. Benz said I had a faulty solenoid valve and that I would need to replace the crank case ventilation assembly. That is $3000. My friend has a C300 sedan and they replaced his under the extended warranty that came out on August 2023 for the crankcase. I have the same exact issue but they said my VIN doesn’t populate so they cannot do anything. This is the 2nd faulty crank case in my car, it was replaced by warranty in 2019. I don’t drive that much I have 47K miles on the car. They refuse to cover the faulty part.

Check engine light on on 2017 Mercedes C300 4 Matic. Car has 52,000 miles on it. The code P052E71 was diagnosed by Mercedes mechanic as the valve for the crankcase ventilation. The actuator was blocked. Mechanic said part (crankcase ventilation hose) is not available and this problem happens to all 2015-2017 C 300 models usually around 50,000 miles. When air conditioning or heat is run it causes an odor of burning fuel or oil in the cabin. Mercedes said part is not in stock and they have no ETA on when it will be available.

The contact owns a 2017 Mercedes-Benz C300. The contact had received notification of the federal safety agency Campaign Number: 21V032000 (Seat Belts). The vehicle was taken to a local dealer and the recall repair was performed; however, upon retrieving the vehicle, the check engine warning light illuminated upon starting the vehicle. The vehicle was taken back to the dealer and remained in the dealer possession. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 34,000.
Check engine light came on. Error code indicates a PCV crankcase ventilation valve has malfunctioned. Code is P052E. This is a notorious problem with Mercedes, BMW and other European cars. It should also be considered part of the emissions system. Contacting the MB dealers, I cannot get a clear definition whether it is covered by extended warranties or any warranty whatsoever. They are vague as to "maybe, but not sure". I feel that there should be a recall to fix the defective parts involved with this error code.
My vehicle started shaking and the check engine light came on. It's a PCV valve
I took my vehicle to the mechanic due to the check engine light been on. The diagnostic came back to be that "The valve for crankcase ventilation has a malfunction. The actuator is blocked." As per mechanic this has to be replace but cost around $ 2,000 plus.
