    2009 Audi A4 B8, Steering wheel (talk button) issue

    I have a 2009 A4 B8 non-NAVI. It has worked for several years until now. I am trying to troubleshoot a problem with my steering wheel (talk button). The other multifunction controls on the steering wheel work just fine. The problem is intermittent meaning I can be parked on a fresh start in the morning and hit the talk button and it works normal meaning I can provide a command per the Audi manual. But once I start driving the talk button does not respond once it is pressed and if I would drive to a location put the car in park (still running) and press the talk button it still refuses to work. So here are the general problems;

    When I press the steering wheel button (while I am driving) it will not go into voice command mode for dialing etc. It does absolutely nothing.

    Incoming calls into my mobile phone (while I am driving) do not always trigger the telephone mode screen to turn on, and/or the call does not go through to the speakers every time. This is an intermittent problem as well.

    My phone device is an android running (Android version 9). Bluetooth connection to the car works fine. Attached is a fresh autoscan with no errors, which I have done several times. Is there a way to use VCDS to troubleshoot these issues?

    The status of the controls on the steering wheel should be visible at Address 16: Steering wheel, Measuring Blocks, likely Group 007 or 008. Look there when it's working, confirm you can see it change, and check it again when it's not working.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    I ran the measured blocks (006) twice and have inserted the log for a test while the car was parked (ignition running). When the car is parked and ignition off it states that same information because controls cant be used. I then started the car and moved all 4 tested points on the steering wheel. They registered activated until I stopped moving them and that is why the log states not operational.

    Address 16: Steering wheel (8K0 953 568 F)

    15:14:17 Group 007: Multifunction Steering Wheel III
    Not Oper. Multi-Function Button (Left)
    Not Oper. Multi-Function Button (Right)
    Not Oper. Thumb Button (Left)
    Not Oper. Thumb Button (Right)
    I still have 3 issues;

    While driving incoming calls are not routed to the speakers.
    While driving talk button on steering does not engage the voice commands.
    While driving outgoing calls from the car unit should engage my phone to dial out. It does not.


    I basically have to pick up the phone handset if I wanted to answer a call. BTW, the phone is connected to the car via BlueTooth verified on the radio screen and on the phone. I am just not sure which module controls the function of an incoming call. I guess it could be the radio itself which is a Generation III - Symphony III with no navigation.

    I also have considered the clock spring being the issue just because it controls the controls on the steering wheel.

    Has anybody in the forum given my situation any thought? I am stumped at this point. Can the HEX-NET device even help me at this point?

    Had to go to the dealership for this problem. They were surprised that there were no error codes. They were told by Audi HQ that the issues with the Bluetooth side are rare and that the 5F module that controls the BT will need replacement. That part is (8T0862336F). I will replace the module myself with a new or used and hopefully, the current codes in the module will transfer over if there are problems. Will post more once I get there. If there are any pointers from the forum, please reply. Thx
