I'm in enjoying my new MINI, but I may have a growing concern with it. Whenever I start my car in the morning to head to work I get a low-pitch, fast clicking noise while the car is stopped or in idle. It goes away when I give it gas, but then comes back when I stop. It goes completely away after about 5 minutes of driving. I have a 2008 Cooper. Anyone have any sugguestions, before I have to take it and leave it at the dealer for a few days?
