Is your power steering full? Ever change the fluid? Wife's x5 moaned like crazy when it was cold outside. Fluid was low problem solved when I topped it off.

The gas pedal is almost identical to the old school volume knob of a stereo receiver. I think there are two parallel potentiometers for when one fails. If one fails and has an area of low or high resistance it will act just like you are saying "flat spot". It shouldn't be terribly expensive or difficult. I'm betting you can put an ohm meter on to verify

Check the O ring on the reservoir as well. Mine was groaning as well. Opened it up and it had low fluid. also had a fine mist of fluid all over the housing. checked the o ring - hard as a rock. New o ring, no leak and no more groaning.

Same exact experience for me. Weird how the mist just somehow saturates the area with a film and you can't find a point source for it. But yes, simple replacement of the reservoir cap o-ring fixed it for me too.

BTW - tip for those cases where you've got a non-sealing seal and can't immediately replace with new ... sometimes one side of the gasket is harder than the other, so just flipping it over and reinstalling it will improve or even fix things for a while.
