The 210 N22 takes various parameters for the version code P2.

On my '96, the applicable values are apparantly:

+08 - Blower mode bar graph switched on by "AUTO"
+16 - Refridgerant fill level check switched off
+128 - "SMOG" display switched off

Mine was coded at 144 (16+128). I changed it to 8, to display the bar graph in auto mode, which didn't happen. I have no idea if the "SMOG" display works.

Is there something else that needs to be done to honor this code?
