Bluetooth volume levels - may have an answer

[KfabR8]

I don't know if those who own 2010 cars suffer from this, but if you have an 08 or 09, the Bluetooth hook up is, well, LOUD. There seems to be no way to adjust this until you receive a call (and have had the crap scared out of you when it rings). Search the threads and you'll see this has been a problem for many of us.

My bluetooth decided to quit talking to my phone (LG VX8360 - no, I don't have a smart phone...) recently. It would still hook the phone to the car and make/receive calls, but it wouldn't access the phone's contact book, tell me who's calling and such. It also liked to cycle on and off. Bing, hooked up, bing, disconnected. This happened over and over and over, but at random times.

I was able to show Audi that the system was not right and they replaced the Bluetooth module. After changing out the boxes, the new one had to be recoded and in the coding was an option for default sound level - and it was set to 0. My phone doesn't scream at me anymore! Even the tone that tells you it's been connected/disconnected is much quieter.

Now, this is total speculation, but I have to wonder if this coding could be applied to an older Bluetooth module?

If you're friendly with your local Audi R8 tech, it might just be worth while to have him hook up the new diagnostic computer (Audi is replacing the older units) and see if there's any way to set the sound level on your system if it's annoyingly loud.

I want to hook my Ross-Tech up and take a look at the coding for the Bluetooth. If I find anything, I'll report back.

Great info Kfab

I am sure most of us have experienced the "scared the s#it of me"ring.

If we have a solution here that would be fantastic.

What a great way to start 2011 on R8 Talk

Thanks for sharing the info Kfab.

I'm using a Nokia E72 patched thru a 2009 R8. So far the bluetooth connection is perfect all the time. The bluetooth connection tone is about the same tone-level as any system advisory tone.

Yes, that 'CALL' coming thru can be really loud. I did some testing and I found out that the 'CALL' level in the car is dependent upon the RINGING VOLUME that is set in the phone it is connected to.

However, my phone ring level is normally quite high. But fortunately for me I normally listen to music whilst driving. So when a call comes through, indicated by the music-level reducing, I immediately wind the speaker volume down a few notches using the steering wheel volume control. Once the conversation is over, I wind that volume up again

But if you do find a way in setting that call and conversation level, with/without music, it would save us the trouble of touching that volume control.

Thank you.

Best regards,
Ritz

You have to set the ringer volume with the steering wheel controls WHILE THE INCOMING CALL IS RINGING. That volume setting should be sticky, at least it is in my early 2009.

That's partially true, but if you increase the caller's volume intensity during a conversation, that will become the new default intensity when the next ring comes thru, which some describe as 'scary'.

I wished there was a way to separate that ringing intensity and the conversation volume.

I'm just too lazy to hook-up my VAG-COM, but let's see if KFab can determine if that default level within the module will remain for subsequent calls regardless the volume level used in a prior conversation.

That is what I have found too (which is not the case in other cars I have owned like M-B). Hopefully KFab's new discovery will be the solution.

I've been sitting here for the past 20 minutes trying to find the Bluetooth module in the Ross-Tech system. No avail.

If someone can direct me to the location of the module in the Ross-Tech, I'll go back in and see what I can find. I searched the Common, Electronics 1 and Electronics 2 sections and don't find anything that's directly applicable.

That said, the 77-telephone setup would connect/disconnect with my phone as it went through it's modules, but I can't find the coding - or at least a description of the coding. Some aspects will pull up an explanatory menu, others not so much. This falls under the second category.

There's so much available that it can be a tad overwhelming.

I'll get back in touch with my tech and see if we can get some more info.

The bluetooth phone to car connection is rather a small issue for us to be spending our precious time in trying to rectify an Audi issue. Well thanks to this topic, with a Nokia phone, I've now found (a few hours ago) a way to control that ringing tone regardless I have the music on or off, volume was up or down.

KFab, I'm sorry if I had, in anyway, insinuated a rapid solution from your end.

For now, I have more important issues to address with Audi Ag which I haven't got round to. Audi Malaysia is still waiting for that letter of mine in regard to the 'FSI Carbon Built-up', which they will be forwarding to Audi Ag. And there's that issues with regard to my Navigation Unit Plus, where navigation is not possible due to the non-availability of a Malaysian database. I've been so 'lazy'; haven't even got round to coding my ECU to RON97

You didn't rush me at all. I actually felt bad that I brought up the topic w/o having already checked the system out w/the Ross-Tech.

It's one of those annoying things that some of us have had to deal with and hopefully I've found an answer - but now I need to go back to Audi to see if I have. Not sure when that will happen.

I stopped by Audi today, checking on something fun, and since I was in my R8 with my nice quietly connecting Bluetooth system, I got my tech buddy to pull out the computer and play with the Bluetooth/telephone module.

The default sound level IS SETTABLE!!! (woo hoo!)

I've not messed with it w/the Ross-Tech, but plan to later, to see if it's something that can be set by someone other than a dealership with the new Audi diagnostic computer.

Here's where to go:
Module 77 - Telephone
Adaptation channel 128
Basic Volume Setting
Default (on mine) is 0 (zero). It's quiet.

I don't know if this will work on older Bluetooth/telephone modules or not, but it's well worth a try if you have a friendly Audi Tech.

Someone else with a Ross-Tech may want to give it a shot too. Since mine's working, it may be something that came in the new module and shows up now (updated software?). If it's not something that the older modules have, I may not be able to say if it does or doesn't have the ability to be changed. I'll still check, though.

I should try seeing if this is something I can do in my RS6 - that may give us some more feedback on whether it's a doable thing or not.
