This problem may be covered under warranty. Ask your Mercedes-Benz dealer.
I bought this car as a dealer certified vehicle with 40000 miles on it. I heard the knocking on start up and brought it to the dealer's attention the first time I had the car serviced. Bearings were replaced under warranty and I appreciate that but this is not a problem I would expect from Mercedes. I'm disappointed.
