    Boost Blues

    Still haven't come to terms with my 0,4 bar issue. Car is choppy on low stable revs.
    So far I've tried:

    * MFTS replaced
    * WGFV replaced (the old one was not functioning)
    * Fixed leaks (MAF to turbo hose, IC o-ring replaced with Mark-H mod). Before this, pressure went to 0,4 then the needle went back down again during acceleration. Now it holds at 0,4. No real pressure-test done so far, will be done.

    The last point has me believing that this is an electrical/sensor issue more than boost leaks. I haven't been able to read fault-codes from the ECU (any swedes know what VAG charge for reading fault-codes?). I know MAF problems may cause this but mine seems ok enough from looking at it though...I'm getting really frustrated here.

    Ideas are very welcome. Also if someone in Västmanland, Sweden has a VAG-COM and is willing to help, I'd really appriciate it.
