Title: Need help with EGT Delete - Audi A6 C5 2.7T AZA-4B0907551R
Post by: ale2.7t on April 02, 2026, 08:01:08 AM
Hi everyone,
I'm currently working on a project for my 2001 Audi A6 C5 with the AZA engine. I need to perform an EGT sensor delete and remove the SAI (Secondary Air Injection) system. I have already pulled the .bin file, but I’m struggling to find a compatible .XDF file for my specific ECU version.
Could anyone share an XDF file or help me identify the offsets for:
EGT (Exhaust Gas Temperature)
SAI (Secondary Air Injection)
This is my first time doing this, so any guidance on the correct addresses for this hardware/software combination would be greatly appreciated.
ECU Information:
HW: 0261207002
SW: 1037354143
ID: 4B0907551R
I am attaching the original .bin file below for you to check.
Thanks in advance for your help!

Have you looked into cross-flashing the S4 files (8D0907551M for manual, or 8D0907551L for tiptronic) which do have well populated xdf?

Using the S4 files would also make it easier to follow along with Nefmoto community project: Stage1 2.7t ME7.1 S4 (APB 8D0907551M-0002

Hopefully someone can chime in if crossflashing from 4B0907551R to 8D0907551M is a bad idea but it has been mentioned as possible.
