Service bulletins for the 2026 Volkswagen Tiguan
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| Dealer 24BD_20260814 | 2026-09-04. Service campaign. UNKNOWN OR OTHER. In 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. Updated ECM software version table to include additional versions |
