    Have you had look in the DV area? Should not be much in the drivers footwell area for boost related stuff. It could also be the map is not 100% right.

    Its a K03 bud... the boost pipe goes down the back of the engine and onto a pancake pipe that runs along to the SMIC in the bumper area (drivers side)

    They use a bayonet fitting and typically fails at that point... I would imagine the leak is coming from that area
