Well cylinder #2 location. At front of the engine the first coil would be #1 so the next one will be #2. You should take to the dealership if still under warranty. But check your plugs and make sure #2 did not cracked when you installed it. And I know others will disagree with this but you MUST USE VOLVO PLUGS on this thing. Bosch and Volvo do not for some reason get along or any other type of plug. But also check your coills. Quick test but you gota be carefull or you will get zapped is remove the coil hold down screw and while it is running gently pull the coil out. You should here that thing popping. If not you have a bad coil. If you want to do it the safe way you can swapp coil#1 and #2 clear the light and drive it again and see if it will now set a PO301 code for cylinder #1 misfire. Also when you remove the coil inspect the boots for arcing marks. If they are marked then replace the coil. Good Luck.
