Good evening all

Can someone assist me with how to remove dtcs from a me7.5 ecu. I am trying to remove the codes associated with second lambda sensor which has been removed.
I am using tuner pro with the attached bin and xdf file for 06A906032HN 0002.
 I will also be looking to do Sai delete on this ecu so any pointers on that will be appreciated too.

Many thanks

Hi nyet
I have started reading through it. I am new to the 1.8t engines so it is a lot of information to take in. I have also been searching through this forum as there are alot of useful topics.
I have previously just played with the PD engines.
I believe i need to alter these two values CDKAT - CWDLSAHK, and possibly another.

Would changing CLAHSH, CLAHSHE remove the dtcs?
To turn off rear o2 would it be CDKAT, CDHSHE &CDHSH?
Thanks for any help.
