Well the hpfp fixed all my issues, car ran fine for another 7k miles, sold it 2 weeks ago as sills were rotten amongst other issues!
If you are experiencing similar symptoms to mine then give the hpfp a try

Been round an ex-work colleague's place today to change the oil and fuel filters.

Normally I just remove the top lid off the fuel filter and swap the filter but he insisted we remove the whole filter housing so we can drain any water out and clean it out.

Ok fair play I thought... However when it came to leave the car conked out and was just cranking with low fuel pressure fault codes.

We messed around trying to get it to start, ended up 'giving it a sniff' of brake cleaner up the intake which it then fired up into life.

I left on my merry way and struggled to get out of his estate. Pulled into a side road, glow plug light flashing, no power.

Ended up being the fact we'd put 2 of the 4 or 5 fuel pipes that they have in the wrong place on the filter!! Swapped the 2 hoses around, cleared the codes and it started up and ran fine. Doh!

OK, so fitted the Power folding mirrors today, all working as they should without having to code them in, does that sound write or should i  go inti VCDS and press the "do it " button even though they work??

Mk5 General Area / Top end tapping noise

« Last post by BuiltdifferentYT on October 11, 2025, 03:34:33 pm »

Hi guys new to the forum I have a 2.0 tfsi BWA from a. Golf gti mk5 but swapped into a caddy van but be had a few issues. One being an engine rebuild so the spec is

JE Forged pistons
Bartek x beam rods with ACL coated bearings
ARP rod bolts
STD main bearings
ARP mains
Cometic head gasket
ARP Headstuds
Bartek 1.8T oil pump conversion with uprated pump
Bartek 1.8T filter housing conversion
X16 New valves
Super tech valve springs and titanium retainers
New seals and gaskets throughout
New stem seals
New genuine cam lifters
New genuine rocker arms
Gates Kevlar belt
New genuine timing chain and tensioner

Now you have a rough idea of spec and what’s been changed (may have not listed everything but as you can see that’s the bulk of it) here’s my issue

Ok so as you know I did a rebuild and it’s done just under 3000miles

When I used the running in oil the engine was quiet from a cold start never had any issues

As soon as I switched to 5w40 I get a tapping noise from coming from what sounds like the top.

So the car will start from cold and you’ll have 2 seconds of no tapping then when the revs drop the tap occurs after around 30 seconds to 1 minute the tapping goes and on the odd occasion will reoccur again when warm but it’s very faint


I found a couple of lifters were blocked and not jetting oil on the cam So I ran a couple of engine flushes and then replaced the lifters and rocker arms with new genuine vw parts alongside fresh oil.

Tapping still occurred I then checked the pressure which was low on idle as I converted to a 1.8T pump.

I have replaced the pump with an uprated unit alongside the 1.8t filter housing and now have 45psi on idle.

The car starts you still get nothing until then revs drop and then taps however the tapping is a lot less faint and does not reoccur again once it has a bit of temperature through it once warm.


Any advice would be appreciated

Can provide videos of the noise if that helps

Thanks

Stupid electric fuel filler flap has decided to play up, it has not locked in the time I've had the car now it sometimes gets stuck unlocked or locked. 

New actuator required, looks a bit of a faff to do as well.

Fitted new fuel flap actuator part from VW £45 + VAT.

Pretty easy to do, torx 20 screw inside the fuel flap then prize the fuel flap and holder out with a plastic trim tool.

Three more torx20 inside the boot to remove the parcel shelf support right hand side to access the wiring plug

Refitting reverse of removal.

Due a service in about 20 days so I fitted a cabin filter and air filter. Need to get it on mates ramp to do the oil and filter etc

Got the rest of the service parts today, Shell Helix Ultra ECT Multi 5W-30 5L engine oil, Bosch fuel and oil filters.

A refurbished BWA engine starts from 3.5k euro here(netherlands). Im sure you can source engines second hand somewhere but who knows what state that would be in.

Thought id upload a picture of the cam.

I kinda want a sedan. Leaning towards the giulia and S3 limousine. A45 AMG is faster tho and have always really loved how they looked, especialy in white with the aero package. Still have to save up a bit so enough time to change my mind many times haha.
