during the VCDS interface test?
You need to reflash the microcontroller. This requires hardware tools like a ST-Link V2 programmer, as discussed in various CarHacking forums . Step-by-Step Reflash: Open the case of the HEX-V2 cable. Locate the programming pads ( SWDIOcap S cap W cap D cap I cap O SWCLKcap S cap W cap C cap L cap K GNDcap G cap N cap D 3.3V3.3 cap V Connect the ST-Link V2 programmer. Use STM32 ST-LINK Utility to erase the chip.
Many clones skip:
If you own a VCDS 2231 HEX‑V2 clone, you’ve probably already run into that dreaded “Revoked” status or “Interface Not Found” message. It happens when the software detects that your cable is a clone and locks it out, turning a perfectly functional tool into a useless brick. The good news is that it can be revived, and with the right approach, you can restore it to a fully working state, sometimes even better than when it was new.

To repair something, you must diagnose it. Here are the top 5 reasons your VCDS 2231 clone has stopped working:
Do not use the interface while connected to Wi-Fi. Conclusion during the VCDS interface test
Not all clones use the Atmega162. A newer generation of clones uses chips. These are more powerful but also more locked down. The standard repair kit does not work on ARM clones.
