:-P

C7 A6? Can't say for sure, but ETKA seems to imply it'll be in the left end of the dash, on the cabin side of the firewall if it's like the A4.

Mike, you've got the front left and front right headlamps, you've got a level measurement arm on the left side front and rear control arms, then you have the control module that reads the movement of the level arms and tells the headlamp motors how to move. There's not a separate control module for left and right, as it sounds like you're implying.

For our A4, it's behind/above the glove box.
