The air suspension just levels it, and there is never any lockout of 7th or 8th gear. Maybe because the engine has so much torque, usually I can pull hills and it just downshifts itself.

I installed a Redarc controller which had a remote button which is all that is visible, so there is no controller hanging underneath the dash in the leg area. The controller can be remote mounted, so I pulled the panel below the steering column and mounted it inside there, drilled 1 hole to mount the control button. I would highly recommend the Redarc to anyone looking for a suggestion. Works flawlessly. Redarc even had the proper harness plugin for it.

My guess is that Audi got around the no-WDH on the gas V-6 (and TDI?) by including air suspension - AWD with rear end support via suspension support, not WDH. Not on my 4-cyl., therefore the low tongue weight. Quite frankly, as an engineer, I think the WDH is a cruel thing to do to any car’s structure. 😀

The Curt Bluetooth has worked fine for me.
