Autotuner KESS3 Failed to Read Audi MG1CS011 ECU?

By | March 4, 2026

Problem:

Tried to read an Audi Bosch MG1CS011 TC298 ECU with Autotuner and Alientech KESS3 programmer.
Both devices failed to read this ECU via OBD.

Trid to bench it with kess3. It showed no support for this ecu.

Any idea?

autotuner audi mg1cs011 1

kess3 audi mg1cs011 ecu 2

kess3 audi mg1cs011 ecu 3

Solution:

No way after 06/2020.

No virtual file no way.

This hw version is really TC298 and is not supported by Autotuner by OBD, neither via Flex/KESS3. Bench is not possible due to security level.

This ECU can not be actually tuned by commercial available tools and protocols.
