    Angry First Post - 2010 VW Touareg TDI Bluetooth issues

    ok I am going to try to put as much information as possible

    I purchased a 2010 VW Touareg Canadian version tdi..it came with Bluetooth (9w3 unit with the delta radio (no nav)) and was working fine...i decided to have a buddy install the aftermarket nav android radio

    He had this great idea of using the stock mic, so he pulled my stock radio out, pulled the 2 mic wires from the green harness and connected them to a mini plug to us with the android unit..this did not work

    I decided I did not like the android unit after using it and went back to stock...now my Bluetooth works except they cannot hear me from the speakers and voice control no longer works

    Here is what I have done

    1) checked the coding on the radio and Bluetooth unit (which I didn't need to)
    2) disconnected the Bluetooth unit from under the passenger seat to reset it
    3) disconnected the amp in the trunk to reset it
    4) I have reset the main battery to reset everything
    5) I replaced the mic with a brand new oem one
    6) I have purchased a new 9w7 unit and tried that
    7) Took it to VW and their testing (after ($118 CDN)) is that the Bluetooth unit is bad and a 9w7 will not work in my car (I have full red cluster) so another 9w3 will be needed
    8) I have purchased a used working 9w3 out of the same year and tried that
    9) tried different phones to see if it was my samsung s7


    All these did not work, no voice controls and no audio(call sound) from the speakers but they can hear me and everything else is working...radio work fine, its only the Bluetooth call sound

    I checked the coding on the new 9w3 and its 4077

    no errors on the Bluetooth unit, sound system or radio

    running out of options on what to check and fix

    any help is greatly appreciated.

    i have purchased VCDS and can provide scans and whatever else is needed

    not sure what else to look at now

    thank you

    Let's start with an Auto-Scan.

    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.

    This can be closed, I was able to spend sometime and find out the issue

    the dealer told me the unit was gone, so I bought a used one and it did the same thing

    I traced all the cables and under the passenger seat (at the harness) there was one wire that was slightly cut where it attaches to the pin..hardly noticeable as I had to trace the cables with a trace tool to find out, fixed and now everything works.
