Changing HPFP / cam follower on S3 8P

I'm going to check my wife's Mk5 GTi at the weekend, I might even use the one I took out of mine if hers is bad.
Just ordered a cam follower kit and will do it before my service next Monday, My car is currently at 76k my question being if my follower has worn through can I just replace the follower and all will be good or will the pieces of metal done some real damage to my engine etc? I must say the only symptoms I get is my car hesitates slightly when I start it some mornings and the oil does smell of petrol slightly as well.

If you buy an ECS Tuning magnetic sump bung (assuming it had worn through) this may pick up the worst of it. Some fuel will get by into the oil, but you'll likely smell it more the older the oil gets
Perfect, thanks Warren.
I should say my wording was a bit off I meant it has a slight hesitation to start some mornings more so when it's colder weather. I just hope when I take the pump off the piston base has not worn a lot if the cam follower has went! Not really wanting to have to buy a new pump as I have spent a small fortune of my motocross bike this month, the joys of having toys!
Does the oil require to be changed if I'm only replacing the cam follower (last oil changed 5k, last November)?

Not unless you find a problem with the cam follower or you find the oil to smell unacceptably petrolly.
Note on the ECS magnetic bung above, I've been reading some awful feedback on them lately, so use with extreme causation (e.g. when doing them up), and suggest only using them to remove any swarf, not for permanent use.
Thanks for the info. Been running on a stage 1 remap but only covered 30k miles so not expecting too much if any signs of damage/wear (I hope)
Good write up, going to check mine this afternoon, other than the obvious cam follower what else is there to check/inspect on the pump itself? Im running Autotech internals so want to check for pump wear and seal wear as i do have a smell of petrol in the oil. is there any seals i should replace? once complete im going to drop the oil for fresh. thanks

Cheers for the guide, Warren!
Just done mine on my A3, which I recently bought. I was expecting to see some wear on the follower but there wasn't... because there wasn't one there! Oh I really hate bad mechanics! Can't understand why you'd do that for the sake of a £30 part! So it is definitely worth checking.
Anyway, I think I caught it in time. I also had the banjo bolt to contend with. If you see that instead of the pressure release valve: swear loudly, make sure you've got a M8 triple square / spline bit, and a bit wrench - Teng do a very good ratcheting one (Teng Tools 1400B) and I couldn't have done it without mine. Just thought I'd pass that on!

I removed my HPFP from a 2006 A4 2.0 TFSi this afternoon. I have one of the later types, so I've got the barbed brass pipe adaptor on the inlet instead of the banjo joint. The tabs on the clip on the inlet hose were facing the brass adaptor on the outlet, so I had to remove the outlet adaptor to get to them. Then I heard the clink-clink noise of a metal component falling down into the depths of the engine. Arrggghhhh!
Does anyone know what this component is? I suspect a washer, from looking at the shape of the outlet adaptor and the shape of the chamber it sits in.
Having spent a couple of hours googling this, I don't think anyone else ever removes this brass adaptor, hence the lack of warnings about bits falling out. People either have the banjo joint, or remove the inlet hose at the other end.
There is a good chance that somebody here has a failed HPFP and could let me have the washer for a feeling of well-being (happy to supplement this with a PayPal donation towards a beverage).
