I picked up a new project recently, in the form of a 2008 Volkswagen GTI with the 2.0L FSI / BPY engine. I've been reading up on problems with these cars and I believe mine has failed a High Pressure Fuel Pump (HPFP) at some point in its past. I'd like to find out what my options are for getting it running well again. As-is the car runs and drives, but has a rough idle, some oil leaking on the back drivers side of the cylinder head (appears to be the valve cover), and two codes P0011-'A' Camshaft Position Timing Over-Advanced Or System Performance Bank 1 and P0089 Fuel Pressure Regulator 1 Performance.
I pulled the HPFP and vacuum pump to get a better look at the intake cam and the results are in the pictures below. First off, the HPFP is new and the cam follower is heavily worn. I noticed the cam chain cover housing where the fuel pump bolts on is all torn up around the follower, I'm assuming this should fit snugly and guide the follower meaning it needs replaced. The cam itself is a later revision with a 2-piece cam and lobe design. The fuel pump lobe isn't flattened out, but it isn't shiny and new either. I'm not sure whether this means I need a new cam or the lobe is replaceable.
ECS sells a kit to replace an intake cam for ~$500 and the cam cover housing is another $150-200 used. At this point, I'm working if my time would be better spent just dropping on a used or reman cylinder head. Let me know what your suggestions are.
