MK5 GTI - tapping/ticking sound from engine
Discussion
My MK5 GTI is making a loud ticking/tapping sound from the top of the engine on tickover but only when warm.
The noise to me sounds like it is from the LHS/drivers side (Cambelt end).
Cambelt, tensioner and waterpump etc all replaced within last 10k. Oil service 5k ago.
The common cam chain / tensioner issue associated with this sort of noise is the other side of the engine so I cant work out where the noise is coming from. I guess the noise could be being transmitted under the engine cover but it doesnt sound like it.
Any Ideas chaps? Its a 2005 car with 95k on it and presumably runs an AXX engine.
Thanks

The fuel pump on those is noisy and sits right on top of the engine but they make a ticking/tapping noise all the time.
The other issue in the area of the top end of that engine is the drive on the camshaft for the high pressure fuel pump. They're known for wearing, particularly on cars that haven't had regular oil changes. I guess if that's badly worn it could cause a noise that would be made worse when the oil is hot.

Definitely not injectors, I can hear them when cold and understand its normal to hear them on the fsi's
Drove it hard tonight to see what affect it would have and safe to say the noise got ALOT louder. Wont be doing that again until I sort it. It sounded terrible on tickover after having been worked. Like a knackered diesel engine.
I'll order a hpfp camshaft follower and do that myself on the weekend maybe. The noise really is bad though and does sound like its coming from the cambelt area. Any ideas given this?

Have you tried it with aircon on and aircon off? Just an idea as the aircon compressors on these were known for being a little flaky.
Cam bucket for the fuel pump is a good idea too, even if it isn't that it's worth changing. I've got an 08' GTi and changed mine at 65000 miles - it had very little wear but did at least give me peace of mind. I've seen pictures of ones that have worn fully through and damaged the camshaft.
Can you make a recording?
Also, can you can narrow down these sorts of noise by using a breaker bar or extension against your ear and touching the other end against various points on the engine/ancillaries. This really amplifies the noises a lot. Just watch you don't prod any spinny bits
This is the guide I used for the cam follower. Whatever you do though, don't cross thread or overtighten those torx bolts when you put it back or you'll be in a word of pain.

Takes about 30 minutes and that's being very steady and careful.

No the aircon! Camshaft follower for fuel pump will inspected. used stethoscope all round engine and cant seem to pin point noise but general consensus is that its at the top and to the left of the engine.

Noise is getting worse and this morning the engine management light come on. The code that was thrown concerned the HPFP. More examination today confirmed that the noise gets ALOT worse just as revs drop from a blip of the throttle on idle. Very horrible noise.
Garage time and whip the cam cover off I think. Doh!
It's probably the 'Evaporative Emission Canister Purge Regulator Valve' on the black box at the front LHS (looking from the front) of the engine bay just in front of the screen wash filler. Stick a screwdriver on the valve and put your ear on the handle end and you'll hear it clacking away. Quite normal.
The black box is the carbon canister. The valve itself is under the engine cover, on the intake manifold.
I reckon it's either the classic cam chain / tensioner wear, or the fuel pump's cam follower has worn through, causing the pump's plunger to chew the cam lobe up.
Hopefully not the latter as it means a new cam in addition to a new pump.

Its booked in with Steve Monk the VW specialist outside Southampton for Tuesday, the chap who services and looks after the mk5 GTi that was featured on here in a Readers Carpool article with 300,000 on it and now has 400,000 on it!
Its unfortunately not the carbon canister this time as I have had a number of proper looks and listens and its definitely from the block. I'm fairly confident its going to be something to be with the oil pick up / HPFP and cam follower / camshaft adjustor / Cam. Its an AXX engine and i suspect has the early swiss cheese inlet cam on it.
Performance is still really good so I'm hoping the cam lobe is ok but I am half expecting it to look square. I scanned for DTC's with my bluefin unit last night and it brought up code P0011 different to that brought up on my mates code reader. I know that among others issues this code can occasionally be brought up when theres fluctuations in oil pressure. My thought is this may be whats occurring and this has prematurely worn the cam follower and consequently the cam.
Im trying not to drive it at the moment as its not getting any better.
Only other things to note is I have noticed it turns over a fair bit before starting from cold and also theres a buzzing noise from the rear that sounds suspiciously like fuel pump/filter/lines noise.
Will wait and see.
Bracing myself.

Our Passat has the TFSI engine but engine code BWA. It has always had a loud intermittent tapping/ticking sound.
The HPFP cam bucket has been changed (because it needed it, not to cure the noise.) It did not make any difference to the noise but it has not got any worse in the last 25k miles.

Mine did that all the time, it was an AXX engine, i was told it was the fuel injectors and perfectly normal. It ran brilliantly, no issues.
Mines the same, though it seems to have gotten better over the year and the half I've owned it, and changing the fuel pump cam follower quietened it a fair bit.Got the car back. Fuel regulator inside fuel filter was apparently playing up and causing low fuel pressure. Changing this has got rid of an irritating and quite loud buzzing noise from the rear and has helped the car start better from cold. Whether it has helped sort the tapping noise, I'm not sure. I am pretty sure its a good deal quieter but whether the sound being present is satisfactory or not I don't know. Specialist said engine sounded normal to him but I'm unsure whether he drove it in anger, then pulled up immediately and had a listen. Will drive it a bit and report back.
