    yeah it's probably the MAF sensor. I had this problem and after I swapped it out the performance came rightback.

    Don't be fooled by audi garages about the price of a replacement. 90% of the time you only need the sensor probe not the full kit. I bought mine from German and Swedish for £69 and it works a treat.
