Its hard to get a recording of this but basically when under mild or light acceleration then suddenly letting off the gas you can hear a very brief rattle coming from the front.

I checked for loose bolts and stuff like that and cant seem to find anything.

Ideas? Ill try to get a good recording of it today after work.

It’s a 2017 SCAB

There is a TSB for turbocharger wastegate rattle noise on 2017 models; it sounds like what you're experiencing.

would this be covered under the power train warranty?
