Audi bulletin A3924712074764_1
What it saysThis bulletin provides service information pertaining to whining noises in the overrun between 110 - 80 mph. NHTSA’s full summary ↓
Audi filed this with NHTSA as a service bulletin dated Sep 6, 2024, received Oct 28, 2024, about the power train. It names 19 model years (2016–2023). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

Is the A3924712074764_1 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
