thanks for that just checked car again it is sitting to one side when i set it to lift it will go up a bit then you can see it going back down again and cannot see any leeks

If you recently had it lowered, check the switch as they are pretty fragile and the front one may have come adrift.

If it's going up at all then there must be power to the valve block.

If it's dropping back down again once switched off it may be the valve block. Could be two in one issues in the valve block, solenoid not opening fully to lift and then not closing to hold it up and fluid bypassing.

What colour is the ABC fluid as may need a flush and new 3 micron filter to remove any debris that may be in valve block?

Lot of info in link by Vilus above

it is new never changed fillter it drops even when car running you can see it drop looks like they have broken the sensor as has cable tie on it

"it is new never changed fillter"

I assume you mean fluid is new but never changed filter....


from Vilus linky...

The first action is to change the ABC fluid filter,
