Hey all... It's been awhile since I've posted here but recently I'm having an issue with my phone. I have an 04 that's been retrofitted with the original Audi Bluetooth module which replaced the Onstar module.

Up until a week or so ago it worked fine. Then it didn't. The phone connects to bluetooth so I know that's active. The car also tries to take the call when someone calls. I have to switch my iPhone over to use the phone as the audio source. I get no audio from the car though and the phone screen constantly says "telephone connecting" on top. I get no signal strength and when I go to the phone setup menu I get an error... It says "error loading URL" and the URL it gives is "http://10.0.0.1/bluetooth/setup.html".

So, would I assume the phone module is bad or the bluetooth?

While waiting for guys to kick in try another phone.

Possibly, but I would also check that all connections to the telephone module are tight, including the antenna. FYI, the BT telephone module is located under the driver's side footwell (on NA spec cars).

ever since iOS 5, mine has worked like junk. Very flaky switching between speaker system and phone, and really doesn't want to answer calls or to release them when done.

Given many others' seemingly similar and overlapping experience--where the common tie seems to actually be iPhones--my bet is much more likely a substandard job by supposedly glorious Apple w/ phone interfaces and bluetooth recently.

My iPhone has the latest OS and works perfectly with A8 (knock on wood at least three times)

Every so often it will glitch and say connected but I won't hear anything. But yet again the iphone itself will have that same issue sometimes where it doesn't ring and just says connected, so you don't know if the call failed or if your on someone's voicemail.

I haven't had any kind of issues and I've had my iPhone 4S for the better part of a year. A module is definitely not working. Otherwise I wouldn't be getting the error code. Other phones will pair but the telephone screen never gets past saying that the telephone is connecting.

So then two questions:

1. Is the bluetooth module separate from the telephony module? My Audi tech buddy said that they were two separate things which would make sense as the Bluetooth appears to be working on it's own.

2. There's a hidden MMI menu I can go into to check for each connected module but I don't remember the sequence to get in there. Anyone here remember?

1. It is one module. From factory it would be under a drivers feet, but retrofitted it can be anywhere. Mine is in the trunk next to Navigation module.

2. Car + Setup for about five seconds.

I would think the best place to start would be running a scan and see if there are any errors being logged. If the bluetooth module itself is failing it should be apparent in your scan, also you may see errors on the CAN bus or optical bus. You can also run some diagnostics on the CAN and MOST ring http://www.ross-tech.com/vcds/tour/optical-bus.html. It will be interesting to see what you find, I too have an 04 and I just completed the OnStar to OEM Bluetooth retro-fit.

1. This is directly contrary to information I've received from a couple other sources. I was told there is a telephony module and then the bluetooth module. In an 04 the bluetooth module replaces the Onstar module but the car still had telephony options when the Onstar module was installed and has the base in the center console that you mount the different adapters to.

2. I got that far but I don't know what menu to go into.

I don't have a VAG COM and I'm selling the car so that's really not an investment I want to make right now... I'm curious too though.
