hi, I have a 08 R56 MC turbo. Recently,the car failed to start the engine from time to time, sometimes it will start up when I tried several times. When my car is running, there's smokes coming of from the exhaust pipes. does it seems that it need to clean the carbon on the intake valve? thanks.

carbon is a common rough starting issue. It depends on what color the smoke is. White smoke - coolant, black smoke - fuel , grey - engine oil.
