98 Jetta TDI AHU 1.9L (944 TDI swap in progress) I moved so now i got nothing but an AHU in a garage on a pallet.
sounds normal, get a mechanics stethoscope and start listening to things. a bit tappy but its usually normal, if you have low oil PSI, (you need a gauge for that, then the valve lifters are probably worn down, you can also try doing a liquid molly purge set up and see if it clears up any, meaning the IP has some wear but again, sounds typical to me

Yeah I agree. Sounds almost like the injectors or pump. If it’s not causing issue, I wouldn’t worry about it at this point. But I’m no mechanic, so there’s that. Is it only coming from that side? Or just in the engine bay?

You can definitely hear 2 different songs going on . First thing to do is remove the accessory belt, most likely it an alternator pulley or something like that.

Yeah no issues, you can hear it as soon as you open the hood. Ive seen other videos with the same sound maybe normal?

Any ideas? Still making the sound on idle and its annoying me.
You were given advice to run the car without the serpentine belt. It would eliminate noises from those pulleys in the path of the belt. Have you done this to see if the sound goes away?
