What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationDue to a software error in the transmission control unit in affected DSG transmissions, certain fault codes that turn on the malfunction indicator lamp (MIL) cannot be cleared after completion of repairs to resolve the underlying problem with the transmission that turned on the MIL. This issue does not impact tailpipe emissions or vehicle drivability. Stored faults may prevent the vehicle from passing subsequent state inspection and maintenance testing.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

Common questions
Source: NHTSA, 49 CFR 579.5Is Audi 37P3 a recall?
No. A emissions communication is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the 37P3 repair free?
A emissions communication is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does 37P3 cover?
The manufacturer filed it against 6 model years: 2023 Audi A4, 2023 Audi A5, 2023 Audi A6, 2023 Audi A7, 2023 Audi Q5, 2023 Audi RS. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
