So suddenly my MIL light turns on as im driving with no symtpoms of the car running any different.

So i hooked up my computer with my VCDS software and ran an auto-scan.
Heres what it came up with:

Any thoughts on the subject or experience with similar codes will be appreciated. I was wondering if it it was an o2 sensor problem or the cats.
Please and thank you!

 

When you clear the codes do any come back right away?

 

The O2 thresholds sound like a winter gas problem. Clear them and buy better gas.
Brake boost vacuum system? Interesting. Does the car brake fine? It could just be a bad sensor.

The steering wheel code won't give a MIL so ignore it.

Good luck on the vacuum issue.

I have noticed that sometimes when i am coming to a stop the car will not stop right away and it almost seems like it will try to start accelerating again.
it does it for a couple seconds then stops.
not sure what the brake vaccum is tho
