Audi, BMW and Mini Cooper Carbon Build Up Correction (Decarbonization)

The Problem BMW and Mini Cooper (along with other vehicles) with Gasoline Direct Injection (GDI) engines are both cars that can experience carbon build up over time causing drivability and performance issues. GDI is a met hod that automakers have used to inject gasoline at a high pressure directly into an engine’s combustion chamber rather than into the intake tract or cylinder port.  Fuel is better measured than older fuel injection or carbureted systems - making the vehicle more fuel efficient, as well as yielding more power with an engine of identical displacement. The Audi, BMW engines and the Mini Cooper N12 and N14 (along with later [...]
