[Biturbos4] VagCom errors

[Adam Jansen]

OK, so I tried out this handy cool new tool for the first time and I need 
help figuring out what the codes mean...

What are the best "OK now you know what's wrong here's how to fix it 
websites?"

I had two codes

One is my O2 sensor
17526 - Oxygen (Lambda) Sensor Heating: B1 S2: Open Circuit
            P1118 - 35-00 - -
17522 - Oxygen (Lambda) Sensor: B1 S2: Internal Resistance too High
            P1114 - 35-00 - -

Is it bad? do I need to replace it? which one?

and my AC isn't working
00792 - A/C Pressure Switch (F129)
            31-00 - Open or Short to Ground

New switch needed?

Any help or a pointer in the right direction would be appreciated!

thanks
Adam
