Robin, if you are having a lot of LHM spraying from the Activa Roll Corrector leakage return pipe (small clear plastic pipe) when you move the roll corrector than this is a sign one of the rams has a very heavy internal leak.

Which hose to which ram was broken and how did you fix it? This may have caused the problem.

To test the ram by pumping they have to be removed. Easy for the front, not so easy at the rear.

one of the hose that control the front ram, not return. I went to a firm that fix hydralic hoses.
I have looked on the return från activa ram when it stands on the ground and there it was no return.

But should it be a high return from the regulator?

But should it be a high return from the regulator?

From the Roll regulator (corrector) no, there should not be. There should only be a small flow when the corrector is moving and none when static.

The ram leakage return only flows when the ram is being compressed and will not flow at all when the ram is expanding or static.

The activa ram are leaking between - + side, I tested to plug one of the hose to the ram and it worked
Now I must get a new front activa ram or repair mine if possible?

Sadly they cannot be repaired Robin, that's the only failure that cannot be repaired on them. It is usually caused by damage to the piston rod and you can often see scores and scratches on it. This is often caused by the concertina gaiter being damaged and allowing road dirt and dust in. It acts as an abrasive on the piston rod.

You're best looking for a used replacement. Don't worry if you get a replacement with a leaking return collar - they can be repaired fairly easily. New rams from Citroen are very expensive

Here's how to repair a ram with a leaking return collar: Repairing Leaky Rams. Sadly this won't help yours but it may be useful if a replacement you find is leaking from the return collar.

I have a young front ram spare if you are looking for one, may be tricky to sort postage mind you.

okey!
Price?

Update!
I replaced the ram with used one.
But same symptom :/
It are working if a plug one of the hose at the front ram. But maybe the tube/pipe goes to the rear activa ram and that are the failure?

Anyone that has a good drawing on activa system?

Up!
