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!).
