Audi A6 4G C7 – Motion Sensor Trunk Release (Kick Open the Trunk)

Opening the trunk with a kick under the trunk can be very handy especially when your hands are full. Originally, Audi released this for the USA marketet mostly but the sensors on 2012 models weren’t working properly or at all as a matter of fact. They’ve stopped offering them in 2013 and then in 2014 started offering the feature again with better, improved module. Make sure, when retrofitting this to get your parts from a 2014 cars or you will fit a ridiculously bad working motion sensor. Note, that this will work only if you already have power-opening of your trunk working.

Parts Required

Here are the parts you need plus a cable from your motion sensor module to the comfort module in the back of the car.

In addition to the big parts, if you’ve purchased less than a full kit, you will need some clipping 4E0971847 and bolts N10415903. For the cables, you may need:

  • 4E0971847  14pcs
  • 4H0973704
  • 000979034E  2pcs
  • 000979009E

Wiring and Assembly

Both are very simple since if you have all the necessary parts, you will see where the module and antenas should go. Wiring is a bit harder if you’re doing it yourself, but with ETKA you should have no problems.

Coding

There’s no coding, the system should work with unlocked trunk 🙂

  1. Hi, when you say power opening of the trunk, do you mean it needs to have the motorized trunk system, or just able to open the trunk with the button on your key remote?

    1. Sorry, I have the electric trunk factory-fitted so I haven’t researched it. I know it’s kinda difficult mod though since a lot of stuff has to be replaced.

  2. Hello, is posible to specify the exact position for the 2 sensors? One sensor will be on top where the diffuser is clamped on the bumber but the second one will be near the bolts (the ones that lock the bumper in place)?

  3. Do you know where is the location of the comfort module?
    I have the sensor module, the sensors and the wiring loom for the comfort module and i am not sure it is located.

  4. Hi, I want retrofit this gadget to my car. I mount antennas and control module inside my bumper and wires are inside the car. I do everything as you are writing but system do nothing :/ (brown connect to ground, yelow/violet to BCM and red/yellow to + by fuse 5A. Thank you for reply

    1. Can you explain how you mount sensors? I read this retrofit is not possible with allroad becouse of lower cover metal bumper.

  5. Yes, full kessy (doors, start stop engine and trunk). I coded it by vcds but if I save changes and switch off ignition coding dissapear and show info before coding.
