PCMTuner Read and Write Mercedes CRD3Plus.A0 via Module 53

By | April 13, 2023

Tried to do CRD3Plus.A0 from Mercedes W205 C220 170hp 2015
Module 53 Infineon TC1797 Mirco 4096KB
PCMTuner Read / Write works fine
Car starts, but turn off with P060100 checksum error.
Tried 2 different Winols Solutions from Tuner. But didn’t work. (you must disable checksum correction as the tool cannot do it, must be done manually)
After flashing car back to stock, car will run.
I took a look, at this guide:
