no. how do i do an ecu reset?

I have a 1999 S80 2.9 that is displaying an "Urgent Emissions Service Required" message. I started it up one morning and it just started missing and I can smell a charcoal type odor when I turn off the engine. Also I retrieved the DTC codes and all of these codes showed up: P0036, P0442, P0136 ...

its the electronic version. Thanx for moving my post for me!

This is my first post so please be patient with me. I have a 1994 850. MY climate control is not working. I can hear the blowers working at each speed setting, but when I select vent, floor, etc. it doesn't change. Any help would be greatly appreciated.
