Nevermind I got the NF business strait but I still would like to know which of terminal 30 and 31 should be used. Also what wire represents the power going to the Bluetooth module?
Bluetooth install under the seat
Ok I think for the time being I am just going to take out my Telematics module and install the bluetooth module under the seat. I plan to do this as soon as I get my Bluetooth module in. Just a few questions to clarify the pin exchange. What wires from the Telematics Harness correspond to NF- and NF+ in the blutooth connections and which terminal 30 and terminal 31 are use from the Telematics Harness or does it matter.

If you check the BT module post, it has all the wiring pinouts for the 54-pin connector.

Thanks for the link I checked it out and I know all of the different pin locations, I might have overlooked the what I need, but I still am confused about which of the two terminal 30 wires you use and the same for terminal 31. In the pin layout of the telematics module it shows that there are two terminal 30 pins at locations 38 and 39 and two terminal 31 pins at locations 18 and 19. Can I just use either of the two terminal 30's and do the same for terminal 31.
I really appreciate the help

I would guess they are the same. They used two wires either to keep the wire size smaller (e.g. if they can't fit 14AWG wires in those little pins, but 2x 20AWG works) or for redundancy (wires routed on different path through the car to make sure that the Telematics still works even after an accident).CZVT07 said:Thanks for the link I checked it out and I know all of the different pin locations, I might have overlooked the what I need, but I still am confused about which of the two terminal 30 wires you use and the same for terminal 31.

Agreed, either should work fine but be wanred... the telmatics uses 0.35mm (22AWG) wires and the bluetooth module needs 0.5mm (20AWG). The good thing is that if you burn up one of your wires, you've got spares already there 
would it be worth it to somwhow join these two wires to prevent melting?
Depends on how "right" you really want to be. If it was my car, I'd just use one of the wires and forget about it. But for everyone else, I'll just give the warning and information and let everyone else decide for themselves.
how risky do you think it is? I mean DO you think that Audi is just doing it to be safe or does the bluetooth really require the extra AWG. I mean I am not that familliar with wiring so I dont know how much of a difference 2 awg is going to make.
Well, the difference between 0.35 and 0.5mm wires is that the larger wire has a cross section that is 50% larger than the smaller wire. This is a pretty big difference and means that it can safely carry much more current.
Without measuring the acutal current demand of the BT module, I can't comment on whether or not the smaller wire is sufficient. I can assume that Audi would use the smallest wire possible, and they obviously determined it to be 0.5mm.

I see, do you know what the awg is on the terminal cables that comes with the TEL interface for the glovebox install?
Only the manufacturer of the cable can tell you that... those are not made by audi, but are instead put together by someone else for the specific installation of the BT module near the glovebox.
Ok, moving on to another question the posts about the k-line, is it needed or not? To recognize the bluetooth module that is.
Hmmm... what's your car again?

The K-line will be required in your car because you do not have diagnostics over CAN. Whether or not the BT module behaves on your K-line is a discussion in another thread. Basically, if you have many devices already on your K-line, your BT module gets testy and doesn't like to communicate.CZVT07 said:2004 B6 A4
