DTC off to SIMOS 7.1

[DeLuXe]

Hi,

I have a Seat Leon 2011, SIMOS 7.1 that need 1 dtc off.
Catalyst System; Bank 1 - P0420

29F400BB is attached.

Thanks for all the help

Best regards,

EDIT: File is read several times with no binary differences. Winols might act weird with this file but its the only one working, I got 2 reads at first but the other file didnt allow the car to start.

I have only seen one picture on how to read this ECU with Kess clone
Can someone elaborate how and with what cable please ? :)


I read this with external programmer but according to two people the file is bad...
Weird enough it starts the car.. Winols swaps bytes but wont cant/wont swap back for CKS.
My tries with Kess give me wake up error issues..


Thanks for all the help! :)
