The only "preventive maintaince" that will keep the flaps in good condition is to use top quality 98/99 octane fuel, the best quality oil, and, most important, drive it like it's designed to, ie use all the rev range, less plod, more whizzzzz!The difference the remedial work has made to the fuel economy is incredible. It’s gone from 30/31 MPG per tank (which i knew was too low) to 42.8 MPG for the first tank post repairs. Very happy with that!
Will be fitting the proboost ECU next month which will hopefully help future proof the FSI. However, have been thinking about other maintenance/problem preventative steps that I could take to keep the FSI going as long as possible. I have read about the manifold flaps being a potential major issue and saw a very nice looking FSI on facebook today with the same mileage as mine being broken for parts due to this issue. Is there any preventative maintenance that can be done to avoid this issue or is it just inevitable that all FSIs succumb to this eventually?
