Rns-E A3 Early 2006 Aerial Issues

Hello

I have just fitted the double din cage to my A3 for an RNSE having come from a single din Concert ii.
I then did a scan with Vag-Com to see if things were all dandy and came up with an interesting code that is not the usual ZF short to ground issue that a lot of others seem to be having.
I have the Single fakra and Black ISO aerials and am experiencing severely degraded radio reception.
