We have unlocked a VAG Simos PCR2.1 ECU using Foxflash ecu tool by OBD. The function requires network connection.
Get Identify, and get an Ori, modify Ori and during write tool applies Patch.
First, read by obd using unlock obd protocol. Fox flash will give you a VR FILE.
Second, write file selecting complete. it will stop at 6%, reboot the writing and then, at 6% again, it asks you to remove the key 120s, then unplug the battery 60s, then plug it 60s and then press ok before turning on ignition.
Fox flash will resume and will take about 20 min. You can now write selecting tables and takes about 3-5 min. Everything is explained in the manual, so it’s easy.

Skoda Fabia 2011. 1.6TDI. PCR 2.1 unlock/write OBD success.
while uploading, the program runs. The battery must be disconnected… The procedure takes about 23 minutes.
Bench mode is easier.
