Intermittant No-Start, Shut-Off

The key fob won't do that. The primary symptom of a dead fob battery is you can't lock/unlock the doors with the remote. If that works then it's fine. Plus the antitheft will prevent it from starting at all (never shut it off while running) and the antitheft light will flash. 

If there's no CEL the crappy scan tool at the FLAPS isn't likely to get you anywhere. Get to a VAG-Com and get actual, useful, VW codes out of it. The OBDII system on a modern VAG product is good for plugging in to a state inspection machine to pass/fail the car. Anything other than that use a VAG-Com to get VAG codes that are more detailed and correct.
