Never seen those before. Did you clear all faults after installing the RNS-E? The coding 0309111 says you have Bose but no SAT radio, is this correct? The two voltage related errors could point to a bad battery (low voltage while you were installing the RNS-E after having ignition turned on for a while)
You may want to post these error in the VAG-COM forum on audiWorld. There are more VAG experts over there. Also, if it's a 2005 S4 it should be a B6.
