Which 557P file did you use? I got 3 revisions, with filename D02/D04/D06. If I remember correctly the D06 had different addresses.

You only posted 2 addresses, I remember seeing a lot more than 2, for lambda probe diagnostics.
Look at the 3.8.2 file again, the one in German (the one you translated). List all the lambda diagnostics, lamp etc etc. Basically you need to read and translate all diagnostics and lamp, and figure out which are for the o2/lambda probe.
Post them here, gona try to locate them on the 5.9.2

Looks like your right. But if you read the s4 wiki, there's more to disabling lambda DTC. 783C / E / 40 / 42 - No exact match that has the same exact combination of values. Removing 783C makes the values too common (00 FF 00 FF 00) 7A10 / 11 / 12 / 13 - values too common (all values 14) 7A57 / 58 / 59 / 5A - also too common (all values 14) Stopped here. Sorry not much help..  |

i appreciate that you even gave it some of your time i will eventually figure it out i compared may files in the last week but the offset is what messes it up all aeb files are close i guess when i figure out the offset i can find the location to disable if this was m7 i could read the file from my car before and after it came on and find its location but i have a wonderful aeb lol

I just re-read this. I assume the CEL you were getting after zeroing 77c4 and 77c5 was for checksum.
So 77C4 and 77C5 worked?

I just tried 77C4 and 77C5. It does work but doesn't completely remove codes related to o2 sensor.
77C4 and 77C5 - is for:
17604 - Oxygen (Lambda) Sensor Heater Circuit: B1 S1: Electrical Malfunction
17606 - Oxygen (Lambda) Sensor Heater Circuit: B1 S2: Electrical Malfunction
--------
It doesn't remove these codes, so removing the sensor will still definitely give you a code for the ff:
16518 - Oxygen (Lambda) Sensor B1 S1: No Activity
P0134 - 35-00 - -
16524 - Oxygen (Lambda) Sensor B1 S2: No Activity
P0140 - 35-00 - -

i still leave mine pluged in the codes you have are for the oxygen sensor signal you need to leave them plugged in the codes i disabled are for the 02 heaters not the signal for the 02 ill look for the location to disable the bank 2 o2 sensor signal dtc to disable it you need the bank one sensor i beleieve that one is important

I managed to delete rear O2 in M5.9.2
If you're still looking for that info, PM me.
