Result:

Failed and the car won’t start.

Properly it is Tprot locked.

A great thanks to all you helpfully people. It is nice to get qualified help when I fuck things up.

I wrote the fixed iRom file from @stabilo in boot mode, and tried start the car, that did not work.

Then I tried to follow the last three steps in the guide from another thread:

Problem: ECU VAG EDC17CP04/14 blocked writing MOD by OBD (so called EEPROM crash)
caused by: ECU remain in programming mode.
1. Read IROM / XROM and EEPROM in bootloader mode.
2. Fix IROM/XROM using bootloader readout and OBD ORI readout (you will probably need to paste part of map zone and chk/RSA zone)
3. Write fixed IROM/XROM by bootloader (do not touch EEPROM!)
4. connect ECU to the car and write repaired IROM/XROM (same used for bootloader) by OBD.
It will automaticaly fix eeprom problem.
