Stephen I just came in to chime in brother - your pump should be ok but yes I would repair proactively - it throws "accumulator filling pressure remains constant error" when its ready to rebuild but again you are proactive like me so just do it for $50 -

Yes you needed to erase codes, use the zero point function, and calibration routine if necessary - personally for raising/lowering the vehicle via DIS I always use zero point function as its so much easier to do it that way than trying to "trick" the calibration routine - as I would call it the "old way" -

How are you liking the slightly lowered height now? I've been meaning to lower mine about an inch as well, but I want to have the rear suspension refreshed before I do so, my -3 degrees camber on the right rear will turn into -4 if I lower it lol
