Hi,

I have a B6 A4 3.0 AVK and I'm trying to re-code my ecu to get rid of P0421 Warm Up Catalyst Efficiency Below Threshold (Bank 1) so my readiness will set and I can pass emissions testing when I have to do it next year. I already dumped my ecu binary with mpps and I've done a lot of reading and it looks like I need to modify AHKATMX, AHKATS, and AHKATSB to numb the sensors, is this correct? I tried checking the M-box addresses given on the S4 wiki but it seems completely wrong which I kind of figured since the minimum value is larger than the maximum value at the same addresses in my bin.

I searched the forums and can't find a definition file for my binary, is there one that exists? If not is there a similar definition file I can use? I found some posts referencing a 559E definition which seems similar but I couldn't find it anywhere.

Thanks.
