Leaky Xantia

Post by **ekaftan** » 31 Oct 2008, 01:15

Just when I thought I had fixed all the suspension gremlins (I even installed diodes!) all my LHM was dumped today to the ground.

The leak comes from just fron of the rear-left wheel (passenger side for the UK, drivers side for me). Any common leak spots there? Will I be lucky and only have to replace/patch some low pressure return hose?

I lost enough LHM to start losing steering in a 30 minutes drive to my place. Leak started after I had left my parking spot at work so I pressed on after checking that the handbrake did stop the car

Up in that area Ekaftan, you have the Hydractive sphere block and hard/soft electrovalve.

Have a check of the block and especially the electrovalve leakage return pipe. I've a feeling there is a "Y" junction in this area to link a couple of leakage return lines into one. It never fails to amaze me how much LHM a disconnected leakage return line can spill.

The return from the rear hydractive starts off in rubber, then joins onto a hard plastic pipe above the LH side of the rear subframe - this join relies on the friction between a smooth plastic pipe and the rubber hose only to keep it together

. If the valve gets a bit leaky, then the flow can blow the joint apart - and it can lose a lot of LHM quite quickly. Access is poor, but improved by removing the spare wheel and carrier. Fitting the pipe back together is a pig - a pair of long nosed pliers through the hole in the subframe helps. I secured mine by fitting cable ties either side of the joint, and wiring them together

Might not be your trouble, but worth a look as a starting point.

You both were right on the money. It was the juction between the rubber and the plastic hoses from the return pipe of the electrovalve...

Its now supported in a couple of tiewraps.

Tiewraps were not good enough... it started leaking 10 minutes after leaving the house monday. I removed the fuse for the hydractive ECU and it does not leak, will try again next weekend, now replacing the hose from the valve with a longer one and adding a hose clamp...
