Title: Failing Diverter Valve or n75?
Post by: DBXdarkangel on November 04, 2022, 08:43:24 am

So yesterday whilst driving back to Devon from Windsor,  the car was driving normal. Then all of a sudden there was no boost around all. Just felt like a 1ltr!
Parked up to do some shopping then came back and it was back to normal. Boosting fine.
Only thing I did notice was when changing gear after it boosted, I can hear a whistle noise like air escaping from a balloon. For a split second.
Had the revision g fitted 6 years ago so do you think it's time to fit a new one?

BTW paid £47 from awesomeGTI and now £62! Ha
