I've recently bought a dead A2 1.6 FSI. I thought it had a blown head gasket but it turned out one piston had broken below the rings and so it had no compression.
I've rebuilt the engine and it now has excellent compression and starts instantly.
At idle it runs very rough but runs fine at high RPM and VCDS shows intermittent misfires.
The main problem appears to be a massively over rich mixture and I have a regular code for fuel pressure too high.
Does anyone know about the operation of the intake manifold control valve 036906336. This looks like its been removed and messed about with before. Can this cause excess fuel pressure? It looks like its an expensive part. Or could the isssue be a defective injector?
Thank you for any help.
