“Car had 69,300 miles (5 3/4 years old) at time of service on 4/18/2023. The check engine light came on the day before. Dealer performed diagnostic- stated it was the Crank Case Ventilation that needed to be replaced. I was charged $2107.00 $1710.00 for labor, $397.00 for parts. I have owned 2 other mercedes well into the 100,000 mile ranges- no problems similar to this. It seems to just be a C300 issue- my car is a C350e. It has been serviced at the dealer every year and is garaged and well taken care of. I read online that c300 have this issue- and would like to report mine as well.”
