What code do I need to have for a cabin air filter to be present?
My VIN:WDDHF8JB5DA690558
Here you go:

Two options: 2-zone (code 580) or 3-zone (code 581)... both feature a filtration filter. What gave you cause to suspect no filter... just curious?

It all depends on the environment that you are driving in, big city, desert, etc. When I was doing my own oil/filter changes on my Grand Ams, I would clean out my cabin air filter every 10,000 miles, when I was in NM, but when I got to the desert in SoCal (Edwards AFB), I would pull the filter at every oil change and clean it out. If I couldn't get it to clean out to my satisfaction, then I would replace it.
