It's a Direct Injection problem associated only with the Turbo Engines like the N54/N55/N20/N63 etc...
It's not a problem with the regular Naturally aspirated engines such as the 128's N52 (and or N51) Just use a top tier detergent gasoline or drop a bottle of techron in your tank regularly.
Our engines spray the detergent fuel onto the intake valves, where as in direct injection the fuel is mixed inside the cylinder and so the intake valves on DI engines can get fouled up by crank case re-circulation gas fed back into the intake.
