Consumer Description

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.
