Citroen C5 x7 hydraulic leak

[Richard Galway]

This is just above the handbrake module above the rear centre spheres. I'm not 100% if this is the cause it just looks like it. No fluid left in the rear of the car everything got dumped on the ground

Marked here

There is also a return pipe, the one with a piece of rubber, if this one is broken he also sucks the lds tank empty.

I'll have another look tomorrow. Fluid was dripping heavily down from above the handbrake module dead centre

[Richard Galway]

Fluid was coming from above the black box and running down the floor onto the ground

[Richard Galway]

Yep this is definitely the culprit of the leak.The pipe runs from the rear where the centre spheres are located up along the handbrake motor above the fuel tanks along the right side of the car clipped to the inside of the chassis. I've marked it below where it's clipped onto the drivers side of the chassis. I'm not sure if there is a joint above the fuel tank as its out of sight or just one full body length pipe. Would appreciate if someone could post a part number.

The pipe starts here under the boot floor

Sorry to resurrect an old thread but I've posted about a leak on mine and I'm pretty sure it's the same pipe as you've replaced. It runs along the chassis right side and up over the fuel tank and above the handbrake motor. Is the the part below in the illustration? No1 inbthe picture

[KennyW]

Yes, that's the correct pipe. But as Graeme said the Citroen replacement is preformed and made of steel.

Again the most difficult part of fitting is the front from the underbody up the bulkhead to the pump.

The pipework is clipped into the bulkhead and protected by a plastic cover.

Hi. Yes that's the pipe. I'd be amazed if Citroën even still supply it.
I'd have recommend the guy I got my copper pipe from but he was in russia and supplied is a few months before the Ukraine invasion. So... doubt that's an option any more. Shame it's a good solution as it uses specially made pipe ends to adapt. Mine is still all good after 4+ years

[Richard Galway]

I bought 3/16 copper pipe and two union fittings I bubble flared the 4 pipe ends and sorted it in a couple of hours car back on the road thankfully

[Richard Galway]

Fixed the problem with 3/16 copper pipe. I cut the pipe in the rear ran the pipe from the rear up over the rear subframe over the fuel tank and joined the pipe along the chassis. Car working fine no leaks
