The first thing to check are all of the fuses. If they all look good- post back in the comments and we can give you additional troubleshooting steps.

I am very doubtful you have air in your hoses causing the problem. Feel the upper and lower heater core hoses at running temp and verify they are both hot, and should be same temp.(make sure heat is on high in car) Some newer cars lose some heat to the cab just because they are low on fluid. More likely though, you may have a bad radiator cap. If your cap is good, watch your hoses and make sure they aren't collapsing( the hoses will look like they are breathing in and out with car idling). You could even have a bad thermostat, or your heater core could be plugged. You can flush your heater core and see if that don't fix it, but since you have heat then it decreases, your core is probably ok.

12-13.5 V sounds a bit low. Have you checked the alternator? Is there a difference in the voltage when the motor is running (should be higher when the motor/alternator works)? Have you checked the consumption when the car is parked?

This is the indicator for ESP (stability control). If you look on your dash, you'll see a button with, you guessed it, ESP written on it. This allows you to turn your stability control on and off. If your light is on constantly, try pushing the ESP button. If it flashes on and off (ie during hard driving) this simply means it is working.

code p3081 refers to engine temperature too low===causes--allow engine to warm up---cooling system fault
I would check for a thermostat stuck open

code p0322 refers to crank shaft position (CKP) sensor/engine speed (RPM) sensor--no signal===causes--wiring---CKP/RPM sensor---ECM

Have the whole system checked out, the relay is probably just stuck, but your thermostat may be malfunctioning, and your coolant may need flushing.

You are totally confussed here and i suggest you ask a local mechanic to have a look for you ,you may need a new switch mechanism on the door from the sound of it ,these cars can be a bit funny as if you hold the key in the door lock in the open position for a few seconds then the window opens or closes depending on the key movement ,and guess what its all electronic so maybe its the switch mechanism thats had a heart attack in its dear sweet electronic brain causing your problem
