Service campaign NCU - 2024070020

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

Update Digital Operator's Manual. 1. Connect XENTRY Diagnosis. 2. Update Digital Operator's Manual. To do this, select menu item "Quick test view . A26/17 - MBUX multimedia system (head unit) . Adaptations . Control unit update . Update control unit software". Then follow the user guidance in XENTRY Diagnosis. The Digital Operator's Manuals are downloaded automatically via Retail Data Storage to XENTRY Diagnosis to match the affected vehicle. 3. Disconnect XENTRY Diagnosis. 4. Check whether the Operator's Manual in the vehicle document wallet, as well as the supplements and ACCORDION-FOLD DOCUMENT are present and whether the version is correct. The missing or incorrect Operator's Manual, as well as the supplements and ACCORDION-FOLD DOCUMENT must be replaced or enclosed as an aftermarket measure. The Operator's Manual, as well as the supplements and ACCORDION-FOLD DOCUMENT must be determined according to the equipment variant for the vehicle identification number via the parts process in the XENTRY Portal.

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