I get the following error in VAGCOM..

00858 - Connection: Radio ZF output to antenna amplifier
011 - Open Circuit

I have only one "antenna" coax connection to my RNS-E... Should I have two? I have a A4 B6 Avant, with the aerial on the right hand side back window...

Any clues?

Thsi means that the diversity antenna is not connected. What radio did you have before upgrading to the RNS-E? Symphony II and Concert II have the diversity antenna, the Chorus II doesn't. The RNS-E will work with just the HF antenna used by the Chorus but you will continue to see the error with VAG-COM.

In this case I don't think you have a ZF antenna in your car... so it should read "open circuit". I don't think there is a way to code the RNS-E for non-diversity operation because from the factory I believe any vehicle with the RNS-E also has the GPS/GSM/diversity antenna setup.
