Foxflash VAG MED17.1 OTP Sector Not Writeble?

By | October 24, 2023


New KT200/Foxflash keeps getting this message when I try to write it to the replacement DME VW MED17.1. When I try to write Ori file on used junkyard ecu I have this error: “uncorrect file 01000 – OTP sector not writeble.” Any solution?

Foxflash Med17


The ecu file needs to be cloned

OTP’s taken from clone file copied to ori file.

If you can not write in bench, open the ecu and write in boot mode.




I use Foxflash with “tricore clone method boot modality” using bench mode and in this way I have obtained a writeable file.
