idleing isx with def

Amsoil bypass filter will help with the soot. Bmk30 is the part number for the kit I think

 

Having the DEF does allow the engine to use less EGR, which in turn puts less soot back into the system, but it is still there. The main problem with idling is that the exhaust temperatures are too low for the soot to be burned off while operating. So either the DPF has to request a regen during your idle time, or it will do it first thing while running down the road. After some period of time it will just get worse. You really can not idle that much without it catching up with you.
I'm up on the Canadian prairies. I don't need to idle at all at night as it's a decent temperature then. The winters are a challenge. I'll let it run pretty much all day while working, but it still gets shutdown at night all the way down to -30C (-22F). I have Webasto engine and bunk heaters to stay warm during winter nights. Below -30 I let the truck run at night, but it does do a regen about 8 hours later.

 

Possibly! I haven't heard that one yet from him. I just know it's a big additional oil filter, has helped me out a lot, they're good for 80k miles, $50 a filter, and it filters down to .02 microns I wanna say

My 2000 9200i ac works just fine. I keep the evap and condenser clean. Mine has a York compressor not a sanden. Maybe that makes a difference. I did have to replace the fan motor and the resistor once. But if you fix it when it brakes seems to cool just fine.
