79 Sorting out the suspension
Suspension of my XM (engine 3.0 24 ventils, 5 years old) has been too hard since few weeks. If switch
is in position "Automatic suspension", then front suspension is hard, rear is correct. Nobody knows,
what to dowith it. Has anybody had a similar problems?
====
You can do several things to solve the problem:
1) You could open the switch and clean it.
2) you could reset the hydractive computer by disconnecting the battery for 10 minutes.
3) Change the LHM fluid and do this every 40000 kms!!!!
4) Bleed the system 3 times
5) Check the front height corrector
6) Spray WD-40 or similar on each connector that is part of the hydractive system.
7) If these do not work, buy a new XM. Todays 3.0i-24v is a better car.
Opto-sensor
Try all the sensors for Hydractive mode, because if there is a fault condition the car will lock itself into
sports mode - this isn't indicated anywhere on the car unless you want to rig test gear up to the solenoid!
The worst is the opto-sensor on the anti roll bar... being under thecar, it gets a lot of dirt and stuff
nearby...
