    Basically you disconnect the vac line from the n249 that is connected to the inlet manifold. Then disconnect the vac line above the dv. Once you've done this connect the new vac line from the dv to underneath the inlet manifold where the n249 vac line was once connected

    There isn't an N112 valve on the later AMK and BAM. Audi decided it was a crappy idea, and didn't put it on the later ones.
