Default 2019 Wrx Idle Noise Wtf (“CHUGGING” NOISE not INJECTORS)

This is my 2019 WRX. It has 1000 miles and has sounded like this since day 1. I had an EJ257 motor previous to this car, and I have no idea if this is the normal noise the car should be making. I’m looking for some confirmation, and perhaps some other clips I can compare to before I bother bringing it into the dealer. There are no CELs. Acceleration seems fine, and I was quite nice to it for the break in, always kept it under 4k.

Well, it’s not the ticking that worries me. I actually had to pop that question on here once before in regard to my ‘13 STI. I understand the DI probably exacerbates the noise as well.

I am more concerned about that strange chugging noise. I hear it in some videos but not others. My guess would be that it sounds like it’s coming from the camshaft. I hear it in some of the forester videos. But that doesn’t confirm that it’s exactly normal.

Here is mine on cold start. It is a bit loud but it makes the same sound you are referring to as chugging

Hey; thanks for taking the time to record that, yes it appears it does! Strange. I wonder what it’s attributed to.

Totally normal... mine sounds even louder :-).. I first thought it was my valves/rockers ticking due to low oil.. but nope, its hpfp, that's why it even has dampening on it to reduce some of that noise. Carry on and enjoy your loud econo box :-) (shuda bought a tesla if you wanted low noise)

Actually had a ‘13 STI previously, maybe never noticed a similar noise, and I had a fairly loud exhaust, but it didn’t exactly sound like this lol
