IF you don't have information on how to retrieve the codes for the FX3 system, a good repair shop or a dealer can get them for you. That will tell which shock actuator is not working properly.
In most cases, the nylon gear in the actuator that turns the shock shaft will break and is because the shaft is too hard to turn. Bilstein can rebuild the FXE shocks for much less than the replacement cost and can even provide custom valving for autocross or track use. Call them in San Diego at 800-537-1085. Another possible problem with the actuator is a loss of the signal from the actuator to the CCM, which may indicate a wiring or connector problem. In any event, you will need the codes to find the problem area.
If a shop tells you that the shocks are leaking fluid, and need to be replaced, beware! Bilsteins are designed to have more fluid in them than necessary. A slight oily film (which will attract road dirt) is normal on all Bilsteins. Unless you have dripping oil on the bottom of the shock, don't worry about it.
I have FX3 on my 92 and it's a great system. While the console switch provides the three settings, the system is also speed-sensitive at each of the settings. The shock settings will change as the speed changes. I do some autocrossing and open track events with my 92 and the FX3 systems works great there.
