I have deleted the rear O2's based on what is usually disabled on a B5 M-box (CDKAT/CWDLSAHK) yet I'm still getting this code (attached) for this A8 ECU. Code P1177/17585 is what's coming up. 4D0-907-560-AF
Can someone help me with what address needs to be zeroed?

Post cat lambda control limit reached brah.
CLRHK brah.
Just being humorous.
CLRHK=11E2E
I guess just set it to 01 and see what happens.

Hilarious and helpful! As always, appreciate the help man! I'll give it a whirl. Edit, I already have 11E2E 0'd out. Should it no be 0'd and put it to 1? |

What was the original value? The wiki seems to indicate that it needs to be set to an odd number(at least that's my best guess based on the values they suggest). I'd add 1 to the original even number |

1 |ATV not reset on fault memory delete
2 |ATV is reset on engine start
3 |ATV is initialized with ATVINI vice 0

5 |switches dlashkm_w (used for LR variables tblrh and tblrhl)= lamhf_w vice lamhm_w or lamsonh_w
6 |switches dlashkm_w (used for LR variables tblrh and tblrhl)= lamhm_w vice lamsonh_w if bit 5 is not set
7 |disables P part lambda control via !B_lrhkgp
Bit arrangement:

Original value:
00000000 (hex) = 00 (dec)
To disable rear lambda control set bit 0
New value:
00000001 (hex) = 01 (dec)

so... set original value odd (setting odd = set last bit)  Is that CLRSHK breakdown in the wiki? that's some great info! |

I set it to 5 dec just to ensure atv is clear |

The factory file at address 11E2E was 0. Something seems odd about that. Is the address correct for this ECU?

The address is correct, and there is nothing odd about it. The M-box is the odd one with a value of 72.
Set bit 0, or bits 2 and 0. Both will disable trims, setting bit 2 will clear ATV on engine start in addition to trims (Can't hurt, ensures you have no lingering adaptation).
11E2E
0--->5 will prevent the codes.

So I tried 5 and got the following: |

that shouldn't be. That is the ONLY change you made between files?

That was absolutely the only change. I never did try the 01 value though. |

That is very odd. It's obviously the right address, the bitpairs must have changed. Time for some experimenting man. If you want to bring it out we can strap the emulator in and see what's what.
