Hey fellas, recently I've noticed some engine knocking on my '15 GTI. It's more pronounced from a cold start but doesn't happen all the time. Doesn't do it when I drive but will do it if i revv from 2k rpm, as it comes down, it's a diffrent frequency than the valve tick.(again, seems when oil temp is cooler). Doesn't matter if clutch is engaged or not.
-10k miles

-engine temp 200f
-boost -21.0 - -22.6 idle

(It's after I revv it, as it comes down, you'll hear the knock. It does it s few times. Keep your focus off the valve tick)

My car sits a lot with half tank or less for 1-2 weeks often. I usually go to the same gas station. Could be gas related? I do short drives, carbon build up on the colder plugs? I brought it to vw and of course it would do it. They heard the video but couldn't give me much insight. Any suggestions greatly appreciated!

I believe a few others have posted this same thing. At the time I didn't think my car did it, but since then I've heard in on mine too lol. It's normal we've concluded and probably due to VW pulling fuel and adjusting timing to minimize fuel consumption or emissions.

I'd have to check mine to compare, it also sounds like you have the rough idle issue.

Also I hear a bit of turbo or trans whine, again have to compare to mine to see if its similar.

Mine does the same when the engine is cold or moderately warm starting it back up. It really pissed me off because they replaced my cylinder head for nothing and I wish I hadn't taken it to the dealer.

How pronounced is it with the hood shut?

Pretty pronounced. At times it has been louder than what's in the video but I didn't record at those times. The first time I heard it, I was in the car, started after sitting all night, had the window cracked and radio down.
