    Plugs and/or the HPFP. Should be warranty on the HPFP and the plugs need to be changed at 50K, sometimes sooner depends if you do short drives or a lot of highway. Short drives, replace the plugs.

    I plan on replacing my 11 CM plugs in the next two weeks at the dealer, brakes will be done by an independent shop with parts I like.

    Also could be the High Pressure fuel pump. There is a extended warranty on this part so should be free.

    Could be build up on the intake valves and it needs walnut blasted. My wife’s 11CMS had the same issue.
