I tested the auto-leveling yesterday. disconnected the arm from the suspension from the sensor and when I move the sensor arm manually I can hear the pump trying to work. it sounds like a stepping motor, like rotating one revolution and stopping than another one etc... and the car rear doesn't move at all. what should I investigate first, faulty sensor or the pump? how do I test each of them?

i'd bet my money on the pump (

This is more of a question for Jaime/Kevin/Jimbob than a real answer but...

Is the self leveling active all the time the car is running or is it intended to just run briefly at the start of a journey?

[Lazydocker]

Mine runs periodically throughout any journey... I know this because I have a slight air leak from one of the shocks and it has to keep cutting in to level the rear with all the stuff in my boot

today I tested it more carefully and found out that what I was hearing is the headlights adjusting. I don't hear a pump. when i move the sensor arm with the headlights switched on, they move up and down, i.e - the sensor is good. so is it possible that I don't have the rear-end leveling system?

my omega is pretty much as good as it gets, I mean - dec 2002, 2 zone aircon, seat heating, 2,5 bmw, 5-speed auto, xenon, etc... should I expect it to have the leveling system and how do I find out if it does?

thanks

.... and how do I find out if it does?

thanks

Self levelling shockers have an air line connection to them.

I got the car second hand. is it possible that the previous owner changed the shockers with non-leveling ones? and if so I guess the pump must be disconnected so it doesn't pump all the time. I'll check for the air lines, but where is the air pump located?

[feeutfo]

Front wing behind the bumper under the air box. Look up from under the bumper you will see it behind the fog light, check its plugged in.

Or check fuse 27, and that there are two black relays at the top of the drivers fuse panel.

If all present, then pump may have seized if the shocks are non sl from continuous running.

Take one of the rear wheels off and have a proper look at the shock to see if it is a S/L type..easy to confirm as will have a small air line running from about 2 inchs down fron the top..

If all seems to be correct next step would be to confirm if air is being passed from pump to shock.Check fuse as advised by Chris and if that is present and not blown suspect pump is seized up.Worth removing and checking to see if anything is obstructing its operation ,if not next step would be to source a new/replacement pump.Could all start running up some money by now.
