Service bulletin LI27.00-P-073532

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

Complaint If TRANSMISSION 725.1 (9G TRONIC FACELIFT) exhibits any "shift quality" problem symptoms, various optimized diagnosis procedures are available to you for selected vehicle model series with STAR3 architecture, Cause Various Remedy Despite this, the problem shift mechanism should be verified with XENTRY in the presence of the customer as a preparatory measure. In event of shift quality problems, before the start of any repair or standard adaptation, the latest quick test, the transmission control unit log and the EEPROM data should be read out as a txt file (*.txt). The EEPROM data must be stored separately on a data medium (USB stick) as it can no longer be reproduced after adaptation has been performed. Before creating a TIPS case always check that the engine and transmission control unit as well as the dependent powertrain control units (e.g. CPC3, DCDC48EVO1, ISG48V2, LIB48_223) have the latest software release, and update them, if necessary, then perform another test drive. Note: The latest version of the XENTRY (including all available add-ons) must be used for programming the transmission and engine control unit. Only then can it be ensured that the very latest version of each software is installed. If the problem still persists, the creation of a CAN-FD measurement (successor to SD-SCAN for vehicles with STAR3) may be necessary, when requested. For this, the parts specified in the parts scope and the corresponding XENTRY versions / add-ons are required: • W000589002100 Test box 1 • W223589016300 Adapter cable for vehicles with STAR3 • XENTRY 03/2021 with add-on 19516 • XENTRY 06/2021 with add-on 19604 • XENTRY 09/2021
