Chirping sounds in engine bay around 3000rpm

2018 GLA45 (North America). Wondering if this is a normal sound. I only have about 1800 miles on it and I think I might go test drive the two 2019 45s at the dealer to see if they do it or not. If I hold the RPMs between about 2900 and 3100 I get annoying "chirping" sounds coming from the engine bay. It's possibly coming from the turbo or blow-off valve? Anybody else notice this? I did a search and didn't find any threads.
