I've been driving my TDI-swapped Audi A4 for a few weeks now. It's awesome, but the lack of A/C has been annoying. So I finally got my A/C system charged today... and nothing. The compressor doesn't seem to be cycling on/off. My guess is the Climatronic module isn't doing its job for whatever reason.
When looking at the BHW ECU Coding section in VCDS, there's a panel that pops up stating:
As far as I know, automatic climate control was only available on the GLX trim of the B5.5 Passat, and the TDI wasn't available on that trim. But I know for a fact that others have swapped BHWs into miscellaneous cars (A4s, allroads, etc) and got Climatronic A/C working. So what am I doing wrong?
There are no error codes in the Auto Climate Control module.

Mine is coded to 0150031 because I changed it to accommodate a manual transmission. It was originally 0150034. But any attempt to change it to 0050071 is failing with the error message Error 31: Request out of range.Engine Control Unit (J248) Coding
