Service bulletin V971201 2031104

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.

NHTSA's summary

Technical Bulletin (Diagnostic Connector - No ECM Communication): Some model year 2003-2004 V6 Touareg's may exhibit a loss of communication through the OBD diagnostic connector. The signal ground wire may be missing from pin 5 of the diagnostic connector. This document informs how to diagnose, and service this issue.

Listing a model year does not mean every vehicle of it is concerned: the document says which.

A recall listed here may apply to some of the same vehicles. Only the manufacturer can say whether it applies to one vehicle.
