Hi all I’m having some bother with my Q3. It has a 2.1A drain on the battery. By removing fuses I narrowed it down to the climate control unit and then confirmed it by unplugging the unit itself with the fuse refitted giving me a perfect 25mA drain. The climate control unit has 4 plugs on the back so I’ve also narrowed it down to 1 of the 4 plugs by plugging them back in 1x1 until the drain reappeared. The plug in question has 7 wires, 2 of which go to the multifunction control module. Is the multifunction control module Audis terminology for the BCM (body control module)? Has anyone come across an issue like this before? I was hoping the 7 wires on the problem plug would just go to the flap motors making it easy to diagnose but the fact they go to a multifunctional module that probably controls half the car complicates matters.
