How to Remove A6 Climate Control

The Audi A6's climate control unit includes the controls for the heater, air conditioner and heated seats, if the A6 is equipped with these features. The climate control is attached to the dash mount by a couple of bolts, which makes removing it straightforward. However, in order to access the bolts, you'll first need to remove the A6's radio. A special set of Audi radio-removal keys is required to do so. You can obtain them from an Audi dealer or from an automotive parts and accessories store.

Things You'll Need

  • Pliers
  • Audi radio-removal keys
  • Socket wrench
  • Turn off the A6's engine. Remove the plastic cover from the battery. Loosen the small nut on the rear edge of the black battery cable with pliers. Pull the cable away to disconnect the battery.

  • Insert the Audi radio-removal keys into the slots. There is one slot beneath the "Volume" knob and one slot beneath the "Tune" knob. Push the keys in firmly.

  • Apply outward pressure to the keys to release the radio mounting clips. Slide the radio forward by pulling on the keys.

  • Move the radio out of the way. If you need more room to access the climate control bolts, unplug the two connections from the rear of the radio and set it aside.

  • Remove the two mounting bolts from the top edge of the climate control unit with a socket wrench. Pull the unit forward and unplug its electrical harness.
