If the VAG Bosch MD1CS004 ECU manufaucered before 06/2020 (not locked), many devices could read it via the bench mode, foxflash, kt200, launch x-prog3, obdstar, FC200, Flex, KESS3 etc. Here we are talking about the MD1CS004 ECU with version HW80 (bench locked). Are there any devices that can read this ECU?
Use AutoTuner for these ecus. Only if VR OBD is available.
Autotuner release it should VR from server and load via OBD.
VR and write OBD, no bench option on these, though.
People have done many of them with Autotuner via VR. Cannot bench them.
If there is no VR file on server, it cannot be done.
AutoTuner OBD protocol of the Bosch MD1CS004 ECU for 2.0L TDI VAG engines:
About the HW80 hardware:
Some versions can be handled in OBD mode, as this method uses an approach specific to the VAG manufacturer. However, the bench method relies on a specific Bosch service mode, directly tied to the ECU. Therefore, an H80 ECU cannot be handled in bench mode but might be handled in OBD mode.
The protocol now supports a greater number of Cboot versions. As s result, new VR files have been added and several corrections have been made for even more complete coverage.
Readout: OBD VR.
MCU: TC298.
Write time with unlocking: 6min.
Write time once unlocked: 2min.
Checksum correction by autotuner.
If it’s HW31 you need to unlock SFD2 and then you can flash obd. HW80 needs to be unlocked first.
Want to tune new expensive cars, buy more than 1 flashing tool.
