What does this engine clicking noise sound like to you?

Had this clicking sound coming from the engine for the last couple of weeks.

It only happens when you're accelerating from low RPM. For example, if you're crawling and then go to accelerate in 2nd gear, you'll hear this clicking/rattling noise between 1,000-2,000 RPM.

But in general driving the noise isn't there. It's just when accelerating in a higher gear, or blipping the accelerator in a certain way when stationary (like in the video).

I'm not getting any error codes, and the car feels absolutely fine to drive. It's just this clicking noise at low RPM.

Any ideas what it could be?

OllieVRS:
This might be a long shot, but have you ever had the cam chain done?

If you have VCDS you can check block 093 when the car is fully up to temp, check the phase position value. If it's more negative than -4.0KW that could potentially be the source of the noise.

Thanks, I also suspected it might be something to do with the timing chain. It sounds like it's coming from that side of the engine.

I haven't had it replaced in the last 10 years of owning the car, so I'm assuming it has not been done in its lifetime (135,000 miles).

I checked block 093 hoping to see some bad results, but somewhat annoyingly I've got a reading of -1.0KW. Do you think it could still be causing this noise with a reading like this?

Might be worth doing anyway (assuming this kind of noise isn't suggesting that the engine isn't completely done for). Just wondering if there's anything else aside from the chain and tensioner that would be worth replacing while I'm in there.

Unplug the VVT solenoid and see if the noise stops.

Mine wasn't making that noise specifically but it was clogged up quite a bit because the previous owner neglected the oil changes and cooked the engine slightly. My 93 block was reading anywhere from -2 to -6. In my case, it would regularly throw correlation fault codes and would be sluggish to respond. I could floor it, release, clutch in, shift gear, clutch out and it would still be pulling as if I never let off the throttle.

I ended up going full length, changing the chain, tensioner, VVT wheel and VVT control valve (all INA parts). The car had an instant change in how it accelerates or responds. You tap it and it shoots forward. 93 block is now between +5 and +2 and doing a 3rd to 5th gear pull and a VCDS log, the cam timing specified and actual is almost 1-to-1 with a 0.5 to max 1 degrees mismatch every now and then.

I would also check the cam follower just to be safe.
