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.

P520E code which is caused by a crankcase ventilation issue. The fix costs upwards of $2000. It seems to be a common issue with Mercedes vehicles with 4 cylinder turbos and should be a recall on this system.

Piston one issue. I bought this car from an auction and according to the record on the car the previous owner had problem with piston one and low compression in that piston. After performing some research it looks like Mercedes-?? Benz c300 m274 is riddles with this issue. It-??s all over the internet and I don-??t know why Mercedes is not taking responsibity for this. This car has less than 70000 miles and the engine is locked from the cylinder. Thank you

I recently had to repair a part of my engine with the code P052E. It specifically was "The Valve for Crankcase Ventilation. It stated it was malfunctioned and that the actuator is blocked. It could have caused my engine to fail and my car to stop at any moment putting myself and others at risk. There is a large amounts of consumers with the same vehicle that complained about the same issue. It was inspected by the Mercedes Benz dealership. The only warning was that my check engine light was on.

my 2017 Mercedes C300 experienced what appears to be a very common engine fault with the W205 engine. It involves the "PCV" valve and the engine code fault is P052E. When this fault occurs the engine will stall and sputter. My wife and daughter were in my car last week and it stalled at an intersection which could have resulted in an accident, but luckily the school crossing guards were there to stop traffic and allow her to restart the car and get to the side of the road. The check engine light had previously been on and off for sometime so I had my local Mavis check what the light was on for and they gave me the fault code. I did not think it was anything that serious because the car ran fine. The car was towed today to Mercedes to officially diagnosis the problem

Positive Crankcase Ventilation (PCV) Can cause problem to the engine. Check engine light is on, car have been scanned. This happen one week ago. There-??s no recall for this and happen a lot many Mercedes Benz causing problems on engine and is not on warranty or any other recalls

I have a mercedes c300 2017 and recently I was driving my car and the check engine light came on all of a sudden so I took it to my local shop to diagnose it they told me it was the PCV valve, so I called mercedes and they-??re telling me that this is not covered and of course my warranty is no longer covered I have about 63k miles on the car. Mercedes is saying they don-??t have a recall for this but I-??ve googled around and multiple people are saying the same issue happened to them around the 55-65k range. It-??s super frustrating that this doesn-??t flag a recall.
