Car is at 60,000 Miles and code for Positive crankcase ventilation appeared. Why does this happen to a trouble free car after warranty runs out"????????" Seems like hundreds of complaints all over the internet and Dealer charging big money to fix their design Flaws.
Crankcase (pcv) problem of the 2015 Mercedes Benz C300 Diagnosis code p052e pcv regulator valve replacement/crankcase replacement. The code keeps coming back with check engine light on dashboard. To replace part, the engine has to be taken down since the crankcase is inside the engine. This is a malfunction during assembly/manufacturing, it is impossible to damage part while under usage. Mercedes benz should be held responsible for part replacement and labor. This is a common defect and should be recalled.
Mercedes crankcase ventilation valve has failed, error P052E71. Found that this is happening to thousands of other Mercedes c300, and even after it is fixed it happens again. Reporting this so hopefully it can be resolved with a recall.
Vehicle throwing P052E error (crankcase ventilation valve - PCV) - Has occurred multiple times and has effected numerous C300 models of the years 2015-18. - The car has lower acceleration performance and can be potentially dangerous when merging on highways.
check engine light p052e71 the valve for the crankcase ventilation has malfunctioned, and the actuator is blocked. Replaced the crankcase vent valve assembly 59k mileage when this issue occurred.
Cracked cylinder #1. Causes rough idle, loss of power and lots of white smoke out the tail pipe. This is dangerous for anyone behind the car trying to see through the smoke then loosing power and other vehicles almost hitting me. Mercedes know they are defective but because of the large cost associated with repairing them they will not fix.
Cylinder #1 losing compression. Onset acute after exiting freeway. Car lost power. Engine warning light turned on. Independent repair shop advised compression problem in Cylinder #1. Dealer then inspected and advised there was compression loss in Cylinder #1. Dealer recommended engine replacement (not repair). The car only has around 46,000 miles and is a 2015 model.
The crankcase ventilation valve has gone out on my car. This is a continual problem with these vehicles at low mileage. Mercedes Benz should recall the part for repair as they stated it could damage the engine.
MY VEHICLE'S Positive Crankcase ventilation valve NEEDS REPLACING. AFTER RESEARCHING THIS ISSUE FOR A WEEK IM LEARNING THAT THIS IS A VERY COMMON ISSUE WITH MY VEHICLE'S MAKE MODEL AND YEAR AND IS LIKELY TO OCCUR MORE THAN ONE TIME IN THE VEHILES LIFETIME. THE PROBLEM HAS BEEN CONFIRMED BY AN INDEPENDENT SERVICE CENTER I WAS MADE AWARE OF THE ISSUE BY MY VEHICLE'S CHECK ENGIN LIGHT
