What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationIn some vehicles, a software condition may cause the engine control module (ECM) to remain active after a diagnostic check has been completed. If this occurs, the 12‑volt battery could gradually discharge while the vehicle is turned off. Under this service action, Volkswagen is providing an ECM software update to ensure the control module shuts down properly and to help prevent unnecessary battery drain.

Read by machine from the document NHTSA serves (7 pages), read Sep 30, 2026. A part number is shown only where it matches Volkswagen’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote.
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.

What owners reported

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Volkswagen 24BD a recall?
No. A service campaign 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 24BD repair free?
A service campaign 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 24BD cover?
The manufacturer filed it against 2 model years: 2026 Volkswagen Tiguan, 2025 Volkswagen Tiguan. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
