I think those are good figures but I'm not really sure. The more important 
voltage check is for what is coming from the alternator. On the older Audis 
you could access the diagnostic channels through the climate control unit and 
see what the voltage level is coming from the alternator. IIRC a good voltage 
level coming from the alternator should be in the mid 13 volt range and 
should be fairly constant. Anything below 13 volts from the alternator means 
that you're not getting a full charge to the battery and anything over 14 
volts means you are overcharging the battery and stand a good chance of 
frying it. Sorry, but I don't know what the procedure is for accessing the 
climate control diagnostics on the V6-12 models.

Sorry if I muddied the water for you.
