    Boost pressure?

    Hey all, been driving the Audi quite hard the last few days, Is it typical for the boost to spike to just over 1 bar when flooring it then it will drop back to about 0.9/ 0.8? It doesn't always spike sometimes it will just go to 0.8 only or it will go to 1 bar and hold there

    Its totally standard by the way,
    any help would be good to put my mind at rest as I don't want anything major to go wrong!!!

    Cheers

    Yes mate it's totally normal, It's called overboost. In simple terms, It's where the pressure in the system reaches the limit, say 14psi on an S3, then the system slams the brakes on to stop it boosting further, but it cant stop instantly so it will overboost then drop to the actual pressure limit... If that makes sense?

    Mine is a 210 bhp S3 and it overboosts to about 12psi and drops down to about 9 or 10psi when driving it hard.

    Hope this helps
