Hi Jon.

Glad to hear you like new "new" BX, but it's sounds like you've got a problem here.

The rear LHM leak, it's highly unlikely to be an O ring. We'd need you to be a bit more precise where it's coming from.

Secondly, you don't need to bleed the LHM, the suspension system is self bleeding as it recirculates through the system, only the brakes would need bleeding in more or less conventional manner. Your problem here sounds like the struts are a bit dry, but if the car rides OK I wouldn't worry about it.

To change the wheels, put the suspension up on the highest setting.

Now just the usual safety warning. DON'T GO LOOKING UNDER THE CAR FOR LEAKS OR ANYTHING ELSE FOR THAT MATTER UNLESS THE CAR IS SUPPORTED ON AXLE STANDS OR SIMILAR.

THEY CAN AND DO DROP :shock: SOMETIMES WITHOUT WARNING.

The black rubber thing you describe, I think is the rear suspension gaiter, if it's leaking from the bottom end (nearest front of car) it may be split and need a new one, or it might not be just fitted correctly.
Check the metal bar that crosses underneath it, is not bent upwards as this can cut the rubber gaiter when the suspension is at the bottom.

No need to put the suspension on anything higher than normal setting, even if you were towing a caravan. The system should level itself no matter what you've got in the boot. The higher settings are really only used for getting over very uneven ground and changing wheels.

Ken speaks truth - I'd add that the ride quality will suffer in anything but normal mode. It'll bounce a bit in intermediate, and a LOT in high!

I always rive hydraulic Citroens in normal mode, but we have a lot of those annoying speed humps in the middle of the lane round here, so I tend to use intermediate to negotiate those. You shouldn't ever drive about in High.

I had to drive in high for quite a few miles when those floods hit Sheffield last year, only way i could get out of the deep water. I did lower it on occassion when the water level dropped & the bouncing was making me feel a bit queesey.

It doesnt do any damage to the car does it?

The manual says not to do it because everything's running at full pressure. I guess the combination of full pressure and bounciness makes something more likely to go pop.

Then again, given the choice of driving in High or sucking water into the engine, I think you made the right choice!

When you put the suspension on high you are basically subjecting parts of the suspension to the full force available from the regulator.

Max height means that the height corrector is open. This in turn means that full regulator pressure is delivered to the struts and spheres. The struts extend fully and then the thing tries to compress the gas in the spheres. It can obviously do this for a while as the LHM level will continue to drop for a while.
