2017 Mercedes-Benz C-Class Engine

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

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

Engine code P052E - PCV REGULATOR VALVE PERFORMANCE. Common faulty Mercedes Benz part integral to the car. Just took in the car to MBSeattle.

A very common problem with mercedes. PCV ventilation valve. Fault code P052E

I have a 2017 C350E with 69K miles. Dealer wants $2900 to fix the Crankcase Ventilation Valve. The part that needs to be replaced costs about $600 with lot of labor time involved (~$2500). The part number is 274090560084. The C350E has a 15 year emissions control warranty in California that is supposed to cover "all" emissions control related parts, but Mercedes Benz USA doesn't seem to think this is part of the emission control system. I have done some research and it appears that "crankcase ventilation" is a necessary function of the engine because "blow-by" fumes would build up in the crankcase if it were not ventilated. These "blow-by" fumes used to be vented straight to the exhaust in older cars, but in the 1960's they started to recirculate them with the PCV system back into the intake manifold to limit the emissions. The function of this part seems to do the same thing a PCV system.

My vehicle started shaking and the check engine light came on. It's a PCV valve

My c300 2017 only had 55k and suddenly the engine light on, when I check it show that I need Positive Crankcase ventilation valve replace. it cost $2300.

In my family we have 2 mercedes benz cars one 2017GLC300 and other 2017 C300 4matic and both of the cars have the same issues. Check engine with code P052E. And after talking to friends and mechanics it appears that this issues to be almost on every mercedes car of this engine since both of the cars that are in my family have the same engine components. I request that it should be recall so mercedes benz will repair those issues under warranty. Thank you

My car is throwing the error code P052E. It keeps going on and off.

My car suddenly turned off at a stop sign. After I restarted it, it turned back on and my engine light turned on. I called the dealership and after inspection I was told that the valve for my crankcase was malfunctioning. The total cost, including both parts and labor are $1775. I have seen many complaints regarding this issue with the same vehicle. It is apparent that a recall should’ve been issued for this months ago. It is truly a safety issue when the car turns off at a stop sign or a ramp. I could’ve been hit while my car was stalling on a ramp exiting major highway. I implore you to rectify this issue immediately before someone gets hurt.

Crankcase ventilation valve failure.

Most M274 engines have P06DA00 fault code internally. Harness for oil pressure regulating solenoid valve is short/open inside the engine oil pan. It can cause excessive oil pressure and premature oil pump failure. As the broken wire is sunken in the engine oil, I worry if it can cause fire. If the oil pump fair during driving prematurely, engine can be stalled. Mercedes-Benz knew the issue but they decided to ignore it.

ode P052E : Positive Crankcase Ventilation Regulator Valve Performance. This seems to be a common problem with the C300.It's not an easy fix. MB hasn't addressed this common issue. Also strong smell of gas coming into the cabin during start up. Took car to Keys Van Nuys Mercedes in North Hollywood and was no recall. We are inhaling these fumes and they blamed it on a hose that expands and fumes escape into the cabin. Wanted to charge for the repair but I refused.

The contact owns a 2017 Mercedes-Benz C300. The contact stated while driving 45-50 MPH, the vehicle stalled inadvertently and would not exceed 3 MPH. There was no warning light illuminated. The contact was unable to veer to the side of the roadway. The contact turned on the hazard lights. The contact turned off and restarted the vehicle however, the vehicle would not exceed 5 MPH and was making abnormal sounds. The contact veered to the side of the road for approximately 4 hours until there was no longer traffic on the roadway. The contact proceeded to drive at 5 MPH to her residence less than two miles away. The manufacturer was notified of the failure and assisted with towing the vehicle to the dealer to be diagnosed. The contact was informed that the piston rings had blown out and the engine needed to be replaced. The manufacturer informed the contact that the failure was a known failure; however, she would be responsible of the cost of the repair. The vehicle was not repaired. The failure mileage was approximately 29,650.

Check engine light came on, took it to the dealership. It is the Crankcase Ventilation Valve that is once again broken. It helps to accurately depict emissions. It is a known problem that hundreds of other drivers are reporting on forums https://www.benzworld.org/threads/2015-c300-crankcase-ventilation-valve-replacement-p052e71.3047538/page-1 https://mbworld.org/forums/c-class-w205/739851-check-engine-code-p052e.html There needs to be a recall, this is a consumer protection and environmental safety issue.

Vehicle won’t start or hard to start

THIS CAR IS NOT EQUIPPED WITH ENOUGH PROTECTION FOR THE FRONT RADIATORS TO PREVENT DAMAGE FROM DEBRIS. THIS IS A KNOWN ISSUE FOR 2017 AND UP VEHICLES. THE RADIATOR SEEMS TO BE VERY FRAGILE DUE TO THE DESIGN AND THERE HAVE BEEN MANY REPORTS OF THE ISSUE, BUT CLAIMS ARE DENIED DUE TO BEING 'ROAD DEBRIS' BUT MERCEDES-BENZ FAILS TO ACKNOWLEDGE THIS IS A MAJOR ISSUE WITH MULTIPLE CLASSES OF THEIR CARS. MY CAR HAS 27K MILES AND IS JUST OUTSIDE THE WARRANTY PERIOD. THE RADIATOR IS LEAKING IN MULTIPLE PLACES.

CAR STARTED TO VIBRATE AT IDLE THEN GRADUATED TO SHAKING AT ALL TIMES EVEN DURING ACCELERATION. ACCELERATION VERY SLOW, STUCK FEELING. BROUGHT TO MERCEDES AT 28K MILES. THEY STATED IT IS A CRACKED PISTON IN CYLINDER 1. THIS IS APPARENTLY A VERY COMMON ISSUE WITH THIS ENGINE BUT THERE ARE NO RECALLS YET.

2017 MERCEDES C300 COUPE 49,000 MILES. THIS CAR HAS BEEN TO THE SERVICE CENTER 10 TIMES FOR ENGINE PROBLEMS " VIBRATIING, JERKING, SHAKING AND TICKING" LAST VISIT AT HOEHN MERCEDES,.

HAVE ALREADY HAD PISTON 1 CRACK AND BREAK, MECHANIC NEVER FOUND THE BROKEN PIECE. CAR IS MUCH WORSE SINCE THAT REPAIR. HOEHNN MB TOLD ME THAT THEY WERE REPLACING THE ENGIBE BUT WHWN I PICKED UP THE VAN THEY SAID THEY DECIDED JUST TO REPLACE PISTON #1
