    hard to diagnose over the net, vag com is your friend. new/recon maf from the dealer is £80 in exchange for your old one.

    i would say that would be the j valve causing it to overboost, might wany to swap it back to the stock one.

    Snap guys I bought a house too! Move in 3 weeks.

    Dunno if I will be able to keep the A4 though, maybe have to get something smaller/cheaper. Going to continue enjoying this car while I still can though.

    Yeah try and keep it, i had to sell my Silvia to pay for the house, and the 600 quid e30 318is was the run about and it was a good little run about at that.

    Congrats on the houses guys it will be tough at first but it soon gets easier... with money
