'Telephone is not installed'
 

Always had my phone paired with the car in the past, I got a new phone a few months ago and just never bothered to pair it because the signal is shocking and too sketchy with the reflective glass, but I went to pair my current phone (Android Nokia) recently and got this message on the Telephone screen.

Thought a module was fried or something but get no errors relating to the phone when scanned with VCDS.

Anybody seen this before or know how I can ever pair my phone again? :Confused:

I had this on mine when I bought the car, lift the carpet on the passenger side and open the black plastic box. Unplug the big chunky cable for a few seconds and then reconnect. Made mine work

Sounds promising.

Any idea what the 'big chunky cable' is though? :ROFL:

It’s power and mic etc for the BT phone module

Certainly my interpretation of that message is that it thinks the phone interface module is missing. Does it appear on the VCDS scan and can you communicate with it?

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!

Mine did :ROFL:

I know.... thats why I went for 'long shot' rather than impossible..... +++

Thanks all. Carpet is easy enough to take up so I'll do that to start with and see whats what under there at the weekend.

Still haven't fully got my head around RSAP, whether I have it, need it or want it but I understand it might solve the connectivity / signal issues.

Just as an aside, the same issue affects the VW Passat (maybe other VWs as well). My brother couldn't get his phone to connect despite BT being installed and active. The proposed solution found on one of the VW forums was exactly the same... disconnect it, cycle the ignition, reconnect, and try again. Unfortunately, his still won't connect.

Have you been tinkering in the green menu? Seems odd that the fitted and working module now is not assuming its dry etc.

Have you tried another possibly older phone to see if it works?

It says telephone is not installed (i.e the module) rather than telephone is not connected, i.e. when the module is online but there is no phone connected to it....

I can also confirm that my A8 phone unit went bad but left the MOST Bus working. Only noticed when the phone icon wasn't on the bottom of my MMI screen.

When I checked, I had the same symptoms as the OP; 'Telephone Not installed' messages on the MMI screen and 'Cannot be reached' messages in VCDS for Address 77.

Lifted the carpet and no signs of water ingress; opened the ECU case but no visible issues. But had to fix it by replacing the unit with a cheap eBay replacement.

The original Bluetooth phone ECU in A8s was the 'Handyvorb2'; latterly I believe the 'BTA' [aka RSAP unit] was used instead.

The BTA is a 'better' unit as it uses an external aerial rather than the phone for reception, but although the Handyvorb2 and BTA are 'sort of' plug compatible, you can't easily replace the Handyvorb2 with the BTA as you won't have the external aerial you need.

Handyvorb2 HW part number is 4E0 862 335; it has 3 connections - electrical, optical & BT aerial.
BTA HW part number is 4F1 862 335; it has 4 conections - electrical, optical, BT aerial & external aerial.

Also - RSAP is a mixed bag - effectively your SIM card is virtually disconnected from your actual phone and connected to the car which has it's own cellular chip-set. This means your mobile is not connected to the mobile network any more, the car is!

Upshot is this is great for standard voice - most likely 2G - as the "car phone" used external antennas etc.... But useless for anything else!!!!!! You mobile won't have any data connectivity, SMS/Messaging etc and you end up with two call logs also :ROFL:

I use RSAP on the D4 as it is integrated with the navigation/google maps - it is bearable as there is a wifi hotspot in the car which used the "car phone" to provide data, so you an fudge by using wifi on your mobile to get some access. But even then, it is at maximum 3G speeds and tends to be cludgy.....

S4 & RS4 both have standard bluetooth, in some ways so much easier and no signal strength issues, with the roof down!!!!!

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 :D), as well as centre console drain.

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

The thick foam underneath the passenger carpet saturated with stagnant water, and a slight damp humid smell in the cabin now and then. Needs a good period of warm dry weather to air and dry it out while the carpet is propped up. Doesn't hurt to get a few of those moisture absorbing tubs in there too.

The D2's central drain plugs seemed to get bunged up with leaves and cr@p fairly easily, and it collected within that plug. I imagine the D3's would be the same, unless there is a point further down the drain which is more prone to blockages. Mine was bone dry this time but it takes less than a minute to peel the top of the carpet back now and then just to check the state of things, so certainly worth doing.

Water pouring over your feet when cornering and usually a sloshing sound from behind the dashboard.

There is click r clips missing from the picture here so you would need the pliers to remove them properly to get the rubber elbows off.

Then it's just clean out the elbow and wet vac the part vertical connection and blow out the horizontal connection.

Come to think of it I did think there should be clip or something to secure and tighten the rubber plug - it detached with no effort at all.
