on newer ecu it's possible to lock obd write... don't know if it's the same here, but I'm afraid you will have to write it by bench programmin ;)
found this on another forum:
"looks like ecu has tuning protection, rewrite 95040 with this file and then rewrite your audi1.ori after, you can write to the 95040 in bootmode with ktag or you can use the dos based me7 95040 with any kkl cable, but in most cases I just lift the chip and put it in eeprom reader"
or try boot mode:
