Well finally got my car going, 90k on the clock, suspension is rigid. Not much articulation. Fluid a oil is at the bottom of the dip stick and the front end seems to be out of alignment but I can't really tell if its because the suspension isn't raising all the way.

Any ideas on where to start?

The car will ride pretty hard with bad accumulators, but that won't have anything to do with the height. I would top the fluid off and see where that gets you. Do you get a light on the dash for the active suspension?

No light on the dash. I just ordered the oil to top it off. Ya I figured that bad accumulators would just speed up the rebound and make it rough. Pump wined slightly at startup but that's it

The switch for normal and high height on the center console does not adjust the height at all either. Not sure if that tells you anything more though.

Normally when you turn the switch, there is a green light on the dash which says "HEIGHT" will come on when you turn it from N to H. That could be because of the fluid.

I might check the trouble codes.. Do a search for checking the active suspension codes, and report back if you find anything. Note that code 55 is "all is normal".. IF you have any codes, that would be a good place to start, plus it only takes about 5 mins to do.

No codes, but I know the car isn't raising all the way. It's way out of alignment running that low.

I ordered accumulators but will that affect the height?

Or do I have a weak pump or something?

Do these have any height adjustments that can fall out of spec? It's not out of alignment it's just setting so low camber is off signicantly wearing the inside of the tire.
