    Boost pressure valve fault code on VW 2011 Golf 1.4 TSI GT

    Hello,

    I have a P0243 fault code on a recently rebuilt 1.4 TSI engine, the engine revs to 3,800 rpm maximum.

    The VCDS log is below, all looks fine on the engine so wonder what the issue is? Any suggestions to look at appreciated!

    This scan was just after the car battery was replaced, so many faults due to low voltage show up in the scan..
