Automatically Adjusted Volume

[WCCoffey]

I searched everywhere about the speed/noise dependant volume and says you can't program it out.

I guess the common fix is to unplug the mic, which I didn't want to do because of my Bluetooth, or cut a wire at the AMP. I didn't really want to do that either.

The drone inside the car would make the radio go crazy with your throttle inputs and that was annoying as all hell. So I went through Vag Com because I thought it had to be in there even though the masses said it wasn't.

Long story short if you want to turn off the microphone and/or speed adjusted volume it's pretty simple.

In VagCom go:

56 - Radio

Adaptations

Channel 8

The old value should be 255 if you have Bose.

Enter 000

Test

Save

Done

Has worked perfectly thus far and can't find anything else that has changed.

Good info! I've been trying to solve this mystery ever since I put my exhaust in a few years ago. It would drive me absolutely nuts as to why the volume kept fluctuating whenever I had my windows down and my current fix was put the volume level above 8

[S4Bennett]

Use the TSB that disables the Audio Pilot closed loop feedback. I had the same issue with my FI non-res. It was twice as bad with the windows down.

When you follow the TSB, you'll have to order the wire. It's less and a dollar or two. If you can do the work yourself, that's all it costs. You don't need to enable speed-dependent volume, completely optional.

AudioPilot and BT use two different microphones (both in the overhead light), so unplugging the AudioPilot microphone should work - but VCDS coding sounds better as you don't have to open up any trim.

I thought you could do that in engineering mode?

That doesn't work. I tried that. I think it reverts when the radio goes to sleep.

It does.

[ven0m]

It does.

Which setting do you have to change in engineering mode? I'm also interested because these auto volume changes are annoying me.

I swapped out my RNS-E for an aftermarket and still have this issue! Anyone know if we can make a change without the radio? Obviously vagcom won't see the radio so i can not make the OP change.

This must be a B7 problem. I know that for the stock radio in my B6 (I believe mine is the symphony II iirc, it has bose but no nav), this feature can easily be adjusted to be more/less sensitive and can be completely enabled/disabled without vag-com or any special tools. I just wish I could get mine to work, I enabled it at max sensitivity via the directions in the owners manual but it still never changes the volume, I think there must be a problem with the mic for mine

I believe in 2004 Audi started implementing the Bose Audiopilot system as part of the Bose package. This system has nothing to do with any head unit, it is controlled by the Bose system itself. There is a mic near the bluetooth mic that picks up ambient noises and adjusts the sound accordingly. The only way to disable the system is to perform the TSB that Audi released. Before 2004 and on non-Bose cars they only offer the speed sensitive volume that can easily be turned up and down on the head units. If the car has the Audiopilot system then you cannot change the speed sensitive volume (GALA) settings.

On my b6 s4 the sound would go crazy on hot days and was very annoying, on my b7 it does not seem to ever malfunction.

[SprintBlueWorld]

Wow, I always wondered why the volume fluctuated. And here I thought it was a radio glitch. Never really a big deal but it is noticable.

When I said "It does" I mean "it does revert", sorry for not being clearer.

The B6 has GALA (speed varying volume) not AudioPilot as fitted in the B7 (volume adjusted to compensate for interior noise) so they are entirely different systems.

AudioPilot is, in theory, a better system but it's let down by the temperature sensitivity of the microphone which on both very cold and very hot days just fails to work reliably.

Not sure if things are different for US cars but Audi did also put the Audiopilot in the 04 and 05 B6's here. Not sure if it was all the 04-05's but I know the 04-05 Bose-equipped S4 models did have it.

Not true. My 04 has AudioPilot. Had to unplug it because it would go crazy with the AC on or windows down. Problem solved.

[SlickFix]

I'm going to have to look at my (Bose)Symphony II+, because I swear that I had this issue when I first installed it, but I disabled it in the settings on the head unit itself. Hasn't been a problem since.

[PetrolDave]

Not true. My 04 has AudioPilot.

100% true this side of the pond The 05 S4 I had still had GALA not AudioPilot.

I guess in the US it was different and Audi fitted AudioPilot to late B6s too.

For once we got something better than over the pond folks. Yes victory! On a serious note though, I'm pretty sure my first '05 B6 S4 had AudioPilot as well. I'll have to see what the current one has as it's a late built one.

[2004B6S4]

come to think of it, there's a good chance that a previous owner took the steps outlined here to disable it in my car. There were some other vag-com modifications I found that had been made before I purchased it.

I don't even know what audiopilot is, but the setting I was referring to in my first post is the speed sensitive volume control in the radio that displays svc and then a number. would be cool if that worked as intended.

If you have an SVC (otherwise known as GALA) setting then either your car doesn't have AudioPilot or it's been disabled.
