I swear VW make those bolts from Wensleydale on purpose.

I fnd that bolt requires the correct VW socket and an assistant push the socket into the bolt while the other person applies an even pressure on the breaker bar to free it off.

So that's the dreaded bolt that gets stripped if you don't do it correctly

BLOODY HELL !

Hopefully the noise is gone after all this .

Trouble is i doubt it. Chain was fine and tight.... My only hope now is that it was the oil seals causing the noise.

Really hope this is sorted soon mate

I haven't heard from AKS Alex or whoever answers the emails either ! If we could source another car for my son to run about in for a couple of weeks we would take it to them. He can't be without a car . We want to resolve this issue to then sell the car as he is due another as this has been his car for four years.

As I mentioned before, when the engine is runing, the tensioner could be flapping up and down - causing the noise. When the engine is stopped, the tensioner rests on a ratchet and so can appear fine in its fully extended (chain tight) position. This is why the noise only appears when the engine is hot (thinner oil = more tensioner flapping = more noise) and running.

I'm certainly no mechanic, but thats my summary of the 2nd hand information I gleaned on the lead up to having mine replaced (and noise banished!).

Fingers crossed for you!

Exactly that because the tool recess is stupidly shallow on that bolt.  I had an assistant do the same thing when I did a rear wheel bearing too.  A 40" breaker bar helps too

So i have a major update. Problem solved!!! Car is noise free and running like a dream! Just collected it this morning.

I had the chain and tensioner replaced as i had them anyway even though my mechanic said they were perfect. He is 100% that it was those 3 plastic oil seals on the inside of the cam chain cover. They were brotttle and broken  and causing slightly low oil pressure which caused the noise up top.

Anyone with a diesel sounding gti i would be strongly suggesting to get these rings changed! It solved my issues!

Great News. Put an after video of the engine noise now ? Did you have low oil pressure warning light ?

So this wouldn't be the only cause of low oil pressure , so could be an answer for us to look into that i would think ?

Ill try get a video this evening. Not a sound now inside the cabin and i had that constant knocking sound at idel and outside it sounds like a normal car!

I had no warning light and no fault codes stored. It just wasn't enough to bring on the light but enough to cause the noise....
