Good day! I got my car June 2, 2013 with 12 miles on it. If I start my car, there is a 3-4 seconds of knocking sound. It does happen randomly (warm or cold engine), not all the time. The dealer said it was the injectors. Some people are having there my2012/13mercedes E350 engine rebuilt (connecting rods, pistons, wrist pins), my engine is the new direct injection. Li03. 10-p-054702 is the mercedes memo or TSB? it would be a let down knowing my car will eventually have an engine rebuild also low resale value. I think this is defect complaint though. I need your help or if you can direct me to maybe consumer protection. Thank you and keep in touch.
