Recently my CLS 350AMG came back from the workshop after a major work done...I had replaced the old engine to a second hand perfect condition engine (Original Mercedes Benz CLS 350 AMG)....after the old engine had the continuous & persistent engine sounds that was not supposed to be there.....They had discovered that it was a factory default where the pistons had been positioned about 5degrees off from its vertical position....This has caused the pistons to knocked on the engine wall when raving (Wall inside the engine block) which then caused the prolonged loud disturbing sound....After they had replace the engine & did some fine tuning....my CLS had regained back its outstanding original power and i'm very happy with the works done & of course my car.....The total charges i had to pay was RM11,000 all in....
