KESS3 Update Unlock Module for Bosch MDG1 ECUs

September 4, 2026 Sales ecu-programmer.com Alientech KESS V3

KESS3 expands the range of operations available on the latest “Locked” Bosch MDG1 ECUs and introduces a new dedicated accessory: the KESS3 Unlock Module.

This new accessory is specifically designed to perform the “Unlock” procedure directly in the workshop on MD1CS003, MD1CS069, MD1CP007, MD1CS012, MG1CS042, MD1CS004 (HW80), MG1CS031, MD1CP006, MD1CS005 and MG1CS002 ECUs. Once the unlock is complete, the ECU can then be programmed in BOOT mode, accessing its memories to perform reading, writing and a complete backup of the contents.

This update expands coverage across a wide range of diesel and petrol applications equipped with protected ECUs, produced from 2021 to the present day: from commercial vehicles to high-performance cars and SUVs.

The benefits for everyday workshop operations:

Unlock protected ECUs directly in the workshop
KESS3 Unlock Module dedicated to managing the BOOT “Unlock” procedure on supported ECUs
Access to ECU memories after the Unlock procedure
Reading and writing in BOOT mode
Complete backup of ECU contents
Greater coverage of multi-brand diesel and petrol applications
New opportunities to work on commercial vehicles, cars and high-performance SUVs

With KESS3 Unlock Module and KESS V3 ECU Programming Tool, you can manage the entire operation directly in the workshop, maintaining control over every stage of the process: from the initial ECU unlock to memory access and subsequent programming in BOOT mode.
