The Mark 5 Golf GTI with the FSI Turbo engine has a weak point; the High Pressure Fuel Pump cam follower. They like eating themselves and taking the cam with them.

One of the first things I tend to do to my new cars is service them. This car was no different.
Finally got around to fixing the Fits lazy eye. A few months ago the auto adjuster on the RH headlight gave up and I ended up with one headlight aiming very low. Went for a WOF, passed, just, as they couldn’t adjust it higher (I already tried). Got warned that it probably wouldn’t get through another WOF and I only got this one because it’s aiming low not high.
Right, so the moment i got home today i decided to carry out some work on the M3.
Since i got the car the heater hasnt worked (i knew this when purchased). Neither side changed temp at all, just stuck at cold. I knew this was the heater control valve (HCV), as they are a common failure point as they are easy to block and jam. I purchased some parts from Ray at HellBM, which included a replacement valve.
Its not a hard part to get to on the M3, just a bit tight due to the header tank, and there isnt a lot of space to twist and pull the hoses.
