Quite a few codes, trouble finding threads
 

Hey everyone, I'm new here, my names Turner.

I just bought a 2005 S60 2.4 with 180k miles. Yeah, it's a few, but the drivetrain and motor are fine... for the most part.

The car keeps throwing codes 100A and 140A, which i've seen both diagnosed as the MAP Sensor

BUT I can't find any solutions for codes 600A and 2120, which are Idle Speed and Heated O2 sensor control element, respectively.

All of these are from a SnapOn SolusPro code reader.

Also, the little notification center is saying it's time for a checkup, and that theres an issue with the airbags... wut?

Any help would be super appreciated, this is my first actual nice car. :)
