I have a 2026 US-spec Audi RS3 with about 400 miles on it.

I've noticed a repeatable noise that only happens under a very specific condition, and I'm wondering if anyone else has experienced this.

How to reproduce:

• Car has been sitting overnight (cold start is when it's most noticeable)
• Shift into Drive or Reverse
• Press the brake firmly until the car is completely stopped
• Slowly release the brake pedal just enough to let the car start creeping
• As soon as the car begins to move, I hear a "grr/grr/groan" noise that seems to come from the rear of the car
• I can also feel a slight feedback through the brake pedal

It does NOT happen:

• During normal driving
• During normal braking
• During moderate or hard braking
• If I release the brake normally instead of creeping

Once the brakes warm up, the noise becomes much less noticeable.

The car drives perfectly otherwise:

• No warning lights
• Brakes feel normal
• No vibration while driving

Has anyone with a 2025 or 2026 RS3 experienced this?

If you took it to Audi, what was the diagnosis? Was it considered normal brake stick-slip/brake groan, or did they replace or adjust anything under warranty?

I'll attach a short video showing the noise.

Thanks!
