Service bulletin NCU - 2024020008

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

• Always use the latest XENTRY Diagnosis software release with all available add-ons. • Make sure to follow the operation steps exactly as described in XENTRY Diagnosis. • Use a battery charger to ensure sufficient power supply of the vehicle on-board electrical system battery (greater than 12.5 V). • If XENTRY Diagnosis is already connected to the vehicle, start with operation step 2. If two or more software updates or SCN codings are performed during one workshop visit, operation items 02-4762 and 02-5058 may be invoiced only once for each workshop order. Work procedure 1. Connect XENTRY Diagnosis. 2. Update N129/1 - power electronics (SG-EM) control unit software. To do this, select menu item "Quick test view → N129/1 - power electronics (SG-EM) → Adaptations → Control unit update → Update of control unit software". Then follow the user guidance in XENTRY Diagnosis. 3. Disconnect XENTRY Diagnosis.
