P0432 Main Catalyst Efficiency Below Threshold (Bank 2)
Evaporative Emission System Incorrect Purge Flow
I don't have access to a VAG-COM right now and these are the only two codes showing.
Could this be the o2 sensors?

Anyone have any ideas for these codes? The car idles around 800rpm and flutters to just about cut off at times. It will cut off a few times when starting the car or when the fuel is around 1/4 tank.
It also acts like it has an air leak or an air hose disconnected, but I can't find one anywhere.
I am at a loss on this one.

The cat code is a non-issue, usually, unless it's blocked.
Your purge valve may need replacing.
Did you disconnect the battery recently? If your idle is rough, may be in need of throttle body alignment.

usually when this code appears it is indication that one the vacuum hoses are broken or leaking air
get this http://www.ecstuning.com/Search/ES2532337/ES2532337/
and cut to size and replace every hoses you can get access to,
the first o2 sensor could be related to the code above..
