Hello all,

I am struggling to code out the complete removal of rear O2's on my 2001 A4 2.8 (3B0907551BQ 354164 v0001). I am using uuhsk_2 for wideband input for what that's worth.

The struggle is two fold, I don't have an official definition for my binary. I do have two that are close however Prokonal bits don't line up. And on top of that, I don't know I'm getting all the right info for which codewords to set, even if I had the binary defined properly.

So, with that said, what codeword or codewords are responsible for VCDS 16520 and 16540?

ESKONF has been modified properly for HSH and LSHHK.

CWKONLS - 17
CLRHK - 5

Ori file attached.

Oxygen sensor never passes and oddly enough, evap doesn't pass either but it did before removing the rear O2's.

Thanks in advance!
Nick
