1.6 FSI - day one fault codes

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?
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!

Also due to the driving conditions not the best for the school run nor the supermarket. Needs to get hot and "bothered";)
 
Since I bought it in October, it’s had 3 full tanks of shell v power 98 and 2 tanks of Tesco momentum 99, full service and most consumables replaced so it’s well looked after.

Noted re the need to give it a blast - will do that a bit more!

Mac, re your question on the pro-boost, my thinking here is the preventative aspect as I understand that it adjusts certain aspects of the engine operation to prevent or delay common problems which arise.
 
Filled up my van at the weekend (diesel)……. could not believe that the Super, super petrol was cheaper than the diesel by some 9p a litre????????

Cost me £130 to fill up our van the other day…. The FSI is getting used even more than planned!

Short answer is yes, all normal FSIs will succumb to intake flap failure eventually, but this is no reason to scrap it when it occurs, remedial work is similar cost and time to a cambelt change and that is considered normal.

If you install ProBoost this maps out I believe the EGR and flap function so it can never become a problem, you seem not clear about ProBoost. ProBoost also lowers the coolant temperature to reduce the risk of leaks.

Thanks - I thought there was a link between the flaps and pro-boost but hadn’t gone back to check. Will fit it and if I don’t like the way the car drives afterwards then will remove it again but haven’t read about anybody not liking the effects
