aaronl welcome.
A couple things to know about Your active Q. First, the main parts that allow your Active Q to have such a heavenly ride are ACCUATORS and ACCUMULATORs.
The 'actuators' (Infinity term) mean the strut cartridge with attached accumulator. Accumulators are not available separately (big mistake on their part IMHO)
The 'accumulators' are the small (2"x5") black can attached by 3 small cap screws/bolts the the mounting pad at the end of a 1/2" pipe welded to the (shock) body.
Actually there are 10 one is integral with the pump and a different design. One front center on top of the piping is a 'pump output' accumulator and incorporates a pressure switch. The switch opens/closes the solenoids that allow active oil into the pump. Solenoid closed = no pump horsepower consumption. Then there are the front and rear main accumulators. Front main is in front of right front fender well, mounted vertically, about 2"dia x 10" high. Rear main is mounter horizontally in fromt of right trunk well. About same size as front main. Front 'valve' accumulator is mounted on the pressure control valve--which is by the front main accumulator. This small (1"x 4") accumulator mounts horizontally fore-aft on the front side of the valve assembly and is easiest accessed by removing the headlight assembly and coolant overfloe reservoir. Alternative is to disconnect the valve assembly and drop it out (not a big deal really.) Rear vavle unit is mounted onto the rear pressure control valve, points to the rear,--2 styles (interghangeable) one is 1" x 5', the other 1.5" x about 4".
Each strut has an accumulator (2' x 5" approx) attached by 3 small bolts.When recharging your actuators or accumulators the strut units are ESSENTIAl. Mains NECESSARY for any active control. Pump output DESIRABLE for maximum active system performance and to protect pump solenoids from frequent cycling (could wear them out.) Valve units are helpful for maximum performance - they significantly increase frequency response (on washboards) but only then. They also dampen any 'water hammer' noise if that is a problem--that seems to depend on individual cars and piping rigidity.
The total weight of your active componets is a little over 200lbs. Your acitve oil is a mineral based oil so don't let some idiot put transmission fluid in there thinking it doesn't matter. The oil is should be bought only from the dealer or Joe. It comes in pints at $11.00 a can.
I strongly suggest that you get a FSM on your year Q so you can have pics and ideas where the parts are located and how to trouble shoot. Maybe wes can help you there.
The main problems with the active Q's are: 1) Leaking seals which leaks the fluid or oil.2) Flat or dead accumulators which cause a rough ride, but still allow your car to rise and fall. A flat or dead accumulator needs to be recharged with different fluid. 3) Pumps dying or failing4) Letting your active resivoir go dry. Always check on the active oil level.
Texasoil is perhaps the most knowledgable person in this area and he will recharge your accumulators at good rates.
Hope this helps a bit. Enjoy your active Q while you can as they tend to get a little expensive later in life. Kind in mind that you are driving one of the five most complex cars ever made!
