Great news!!! ALIENTECH company released a new OBD protocol for Kess V3 ECU Programmer on March 28th, 2025. Kess3 now supports VAG Bosch MD1CS004 ECUs installed on 2.0L TDI engines from 2019 to 2025 via OBD.
With the latest update, you can now perform VR reading and write directly via OBD on these ECUs, making your operations faster and easier.
Important note:
MD1CS004 ECUs with hardware H80 can only be managed via OBD. These specific ECUs cannot be accessed using the BENCH mode.
Check compatibility now and take advantage of the new OBD protocol capabilities:
- AUDI: 2.0L TDI EU6
- CUPRA: 2.0L TDI EU6
- SEAT: 2.0L TDI EU6
- SKODA: 2.0L TDI EU6
- VOLKSWAGEN: 2.0L TDI EU6
Extended coverage and VR files:
We’ve significantly expanded protocol coverage across more ECU versions, enriching our VR file library. Many VR files are already available and ready to support your work (although we can’t guarantee every single one!).
