00858 - Connection: Radio ZF Output to Antenna Amplifier
I found this fault code waiting for me today (full text included at end). Does any one have more insight into what this condition from the Radio is? I have cleared the code and am waiting to see if it comes back.
Address 56 -------------------------------------------------------
Controller: 8E0 035 195 A
Component: symphony II NP2 0050
Coding: 00201
Shop #: WSC 00000
1 Faults Found:
00858 - Connection: Radio ZF Output to Antenna Amplifier
44-10 - Short Circuit - Intermittent

HF and ZF
OK. So in radio terms (English to German):
Radio frequency (RF) = Hochfrequenz (HF)
IF Alignment = ZF Abgleich
I then looked in my Bentley manual and see that there is a "Control unit for antenna selection, Underneath the roof frame trim" on my car and in the diagram it has HF and ZF marked on it. I can't be certain but I am guessing the ZF is NOT a signal return cable but a power output cable for the controller. The Bentley manual mentions "...the original Audi radio units have a remotely driven antenna (the voltage supply of the antenna amplifier is driven via a center wire of the high frequency cable)."
So does this error mean that the power supply cable to the antenna control has shorted? Or is this something else?

Do you have an RF device?
I got this code After i install XM Radio RF module. But after i installed an amplified one it went away but i still have another code for the radio.

Nope, no XM, no mods... got this info...
...from the Bentley forum:
Check the antenna at the top of the rear window they are having an issue with board cracking at the hf/zf connections.
Looks like it will be time for yet another dealer visit... grumble grumble.
