Changed my oil and fuel filter. Honestly one of the easier vehicles I've had to do. Fuel filter still looked fairly new, so I'm thinking the dealer did in fact change it, but at least I have a new baseline on everything. Whoever changed it, tightened the crap out of everything though.
After that, I was able to get my on board air compressor mounted. Now I just have to run some power wires and figure out an air tank. I have a small 1 gallon tank that I think will work well. Just gotta figure out where to mount it.

Threw another code. "Crankcase pressure sensor". Google says could just be moisture in the sensor, or really cold weather, which we have had. Or possibly a needed software update? Any input from you platform veterans before I call the dealer?
Are you running a catch can?
