'Telephone is not installed'

Mine would attempt connection but failed every time

The MMI believes the module isnt installed....

Its possible, but unlikely you can talk to it via VCDS... If you can, then maybe unplugging and replugging might reset something, but I think its a long shot.

Due to its location, if you have a A/C or sunroof leak, its one of the first modules to get soaked.... then people remove or loop them out rather than coughing up for a new module at Audi money...

I managed to get a used BT Module for the RS6 for around £150 IIRC from ebay, needs the seat out to fit on mine though not sure on the S8

Shouldn’t be a seat out jobby, I can get to mine with it rolled back

Are these cars OK to disconnect the batteries to or is there a chance the electrics can play up? I know they probably throw up ghost faults but that's not a problem. If they are safe to disconnect then I would perhaps try that first?

C6 and D3 both have their phone modules under the passenger floor....


.... both can be got to with a little effort with the passenger still firmly in place.

My bet is still that its missing or been looped out.

If the unit goes faulty, it dies and breaks the MOST bus, so the whole MMI goes off.

For it to break enough to report as not installed, but not enough to break the fibre loop seems like a long shot to me...

There is no coding to enable a module either, if its on the most bus. It boots and becomes part of the system. Its really pretty fool proof......

I wouldn’t if you can avoid, my car went mental when the battery went flat. It threw up about 30 odd fault codes. They all cleared but scared the schnitzel out of me!

So this must be the telephone module in question, with the aforementioned large plug.




And a picture of the scary amount of electronics under the passenger carpet (which are under a polystyrene panel, upgraded from the D2's wood panel ), as well as centre console drain.

What’s the symptoms of that drain plug? How do you clear any blockages then?
