    Welcome to the forum. If you start a new thread in the A4 B6 section I'm sure they'll be someone there to help you.

    Hi mate you should have your intercooler and the clips checked, I had this problem with my golf 1.9tdi after I got it re-mapped, when i accelerated black smoke came out of the exhaust.

    Once I got up to around 65-70 like you the power died and I would have to turn the car off and back on to get the power back!

    First job is get it on VAG COM sounds like you've got an over boost problem most likely due to clogged VNT. VAG COM can force the actuator to move without engine runing. If it doesn't move freely a shap tap with a nylon hammer normally kicks it into life. Followed by a good thrash to clear the Vanes. Steven. Home - SJM Autos

    if that doesnt work you can clean the turbo veins in situe with a product called innotec, its about £40 and it a three stage process that can work good too,
