What does this engine clicking noise sound like to you?

Fingers crossed.

Bang on. When after 13 hours of drilling (including 3 journeys to the shops for drill bits), and continuous muscle pain from holding the drill in place, I actually cried tears of happiness/relief :grin:

Use Cobolt drill bits I drilled mine out in minuets, they’ll cost the same as the Vw tool though.

Managed to replace the timing chain (and camshaft adjuster) today. The exact same noise is still there though.
Any ideas what else it could be? Any chance it could be a faulty injector making the noise?
NOTE: For what it's worth, I managed to get the cam adjuster bolt off without stripping it. I could feel it starting the strip in the night when trying to crack it off, so left it to the morning fully prepared to have to do some drilling. But I gave it one final go in the morning before drilling just to see if it would come off or strip, and by the grace of God it cracked off.
OllieVRS:
Well done on getting job done without problems.
I'm now stumped by the noise even more. Unless some engine genius on here can weigh in, it might be time to start throwing money at different parts.
Maybe time to give VCDS another shot to check if any fuel/air related numbers look strange when the noise is happening, do a live monitoring of the 4 misfire counters, check fuel pressure is meeting the requested amount, etc?

Did you check the cam adjuster seals as they can crack, wear or break off completely.
They control the oil pressure at different rpm stages. If one fails it could cause a rattle at idle, mid rpm or high rpm......I had the first and last issue over the years related to these rings. Last one related to wear when I got the car and the first one from when the cam chain was replaced with new rings, but one had unexpectantly broke during refitting :confused: Another set of rings and very careful refitting, and it has been fine ever since.
