    Havent had a chance to try switching the diverter valve yet, but now, on my way home, the bloody thing wouldnt even boost past 0.5 bars. I had almost forgotten how painfully slow a stock A3 1.8T feels :(

    I also have had it on vcds, aswell as an Audi dealer computer, and both show the same error, which translated into english means: "Regular loss of boost pressure".

    No, havent. Could it have anything to do with the 2 hoses i left out of the loop? The one originally going into the top of the DV, and the one sticking out of the black box that has to do with the 249 system. I just stuck the screws the box was bolted with in them.
