I bought my
mcs about 4 weeks a go, and it had 1 weeks manufacturers warrenty left and obviously the 12 months cherrished. I had this rattle and recorded it on my phone as it didnt do it evertime. I phoned my dealer up and told them about this rattle and that they could drive the 25 miles to mine to pick it up and bring me a courtesy car while they were repairing it. They did as i asked and fixed it under warrenty. It was the cam chain tensioner. I had good service from my dealer
