How to change Fuel Pump Cam Follower on 2.0 TFSi
v4rley:
@NickGTi That is some serious wear considering it’s only done 10k, what was the cam lobe like?
pudding:
Fairly typical of tuned TFSIs! Once the DLC coating rubs off, it's not long left for this world!

It's closer to 15k after checking, the cam looked fine upon inspection.
The car is stage 2 spec so to be expected I guess.
Glad it's all done though!

Many thanks OP for this guide. :happy2: :happy2:
Tackled this today on my 2005 AXX with 74k on the clock.
Had a banjo bolt pump but used a 10mm ratchet spanner and taped up the m8 12 sided spline tool from my Hilka set (same as the machine mart set mentioned in an earlier reply) to the ratchet and worked a treat getting the bolt off and back on.
Be aware that the banjo fitting needs to be slightly lifted away from under the pump to free it as there is a lip on the pump allowing the banjo fitting to seat back onto the pump.
Case hardening was starting to wear through on the tappet so a wise move it was replaced now.
Also fitted a new o ring as the old one was brittle and had to be lifted off the pump with a flat head screwdriver.
Took 30 minutes start to finish.
Regards

Managed to check my cam follower yesterday afternoon, it’s done roughly 15,000 miles & looked in very good condition on stage 1 tune, also cam lobe looked A1.
I did find the HPFP piston & spring quite stiff on inspection (maybe normal) but after a good few compressions of the same with palm of my hand and making sure I pushed it dead straight and supported the HPFP with my other hand it did seem to free off a little, car seems to to be a little more smoother & positive after this!! Not faster
Anyone else had this, or is it all in my head :thinking: Seem to enjoy driving it more today & even took it for a spin down back roads
