Last day or two I've noticed a noise coming from what seems like the rear main/clutch area. When I first heard it I thought I was another victim of the exhaust leak (my car is job 1 mid Sept build) but then realized it couldn't be that because it goes away by dis-engaging the clutch.

It's intermittent and seems to pretty consistently happen on cold starts until I drive a little and it warms up. It's clear in the video but in person it almost sounds like a metal brushing noise (think metal yard rake against another metallic object (pressure plate maybe)?

In the video, I record with my phone from both sides, under the car about center of tire. Towards the end I push in the clutch pedal and release a couple times and the noise pretty much goes away, and comes back, however, the idle RPMs pick up about 100-200 when I press it in and drop when I re engage like it's under load (more than normal, neutral, gear and tranny noise).

Clearly it has to go in to the dealer but should I be concerned driving it in the meantime and have it towed? Has anyone had the same issue and/or point me to a thread? I can't find anything similar.

Thanks!

They couldn't replicate it even though it made the noise as soon as I started it up at the dealer when I picked it up. I'm pretty sure mine is the exhaust leak though.
