Stalling issue - FIXED, YEAY!!!!
Boothy:
Changed the cam follower and fuel filter today and it hasn't solved the issue of stalling all the time. In all honesty thought the cam follower seemed it ok condition to be honest. It shows some sign of wear as you would expect from two pieces of metal contacting each other but it looks far from fooked if you ask me:
The surface is still intact and flush, not concave like the really worn ones I've seen on the web. It basically looks like the brand new one but with a little silver patch it the middle. Even so i decided to put the new one it whilst it was apart.
I'm happy in a way as it means that the camshaft shouldn't be worn either so that won't need to be replaced. Hopefully the most expensive part now would be the HPFP and I can cope with that.

The DLC on it has worn off so it would wear alot faster now - good idea to replace it.

I want to start this update by saying VW dealers are just plain money grabbers. When I took my car to them they wanted £300 in diagnosis costs alone! They believed the camfollower, camshaft and HPFP were all knackered after looking at the two fault codes the system showed.
Because of this I had the car towed to a a local VW specialist for a second opinion and thank god I did as it has saved me a lot of money.
He checked various bits and bobs and then did some research into the fault codes that resulted in coming across further information relating to a faulty low fuel pressure sensor. He ordered it and then removed the old one for inspection before fitting it. The old one was in a bit of a state to be honest too. Really covered in gunk and dirty when it should have been clean. I also noticed that the fuel that came out of the fuel filter when I replaced it was extremely dirty but the fuel from the inlet lines was clean.
Because of this we decided to replace the sensor and instantly fixed the stalling issue which was very good news however the proof would be in the driving as that it where the problem had first become apparent.
So I set off and initially everything was fine so I gave it some beans. Straight away then the car began to do the same thing but less noticeably however when at idle it was all over the place. Burbling and then nearly stalling and then just revving up to about 2k and then back again? My heart sank but then I realized that I had had a similar issue when I had an air leak on another car. Got home, removed the engine cover and discovered one of the air lines to the PCV had come off completely! I know it was on when I replaced the camfollower so not sure how its come off but as soon as put it back it was smoother than a babies arse! I've secured it with new clip too so hopefully won't happen again.
So. The price at VW to diagnose the issue - £300.00. The price to fix the issue at the specialists - £60.00. The smile on my face - priceless!
