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
