Hi group. I own a Audi A6 C8 2024 40 TFSI with nearly 40k ml. Does anyone have or had a similar issue? On a cold start the car is reving up to 1100rpm(which is normal), but when the revs dropped to 900rpm is doing an rattling noise. Is this normal? Audi dealership said is normal. 20260603_050835.mp4
