Xantia front height corrector pipes

[Dommo]

Hello all

Currently half way through repairing my Activa front height corrector, and we've found that one of the 3 pipes is full of muck. It's the pipe on the drivers side of the car, on the opposite side of the other two pipes. I'd like to undo it at the opposite end and blow the muck out if possible.

Does anyone know exactly where this pipe goes? According to servicebox I can only see 2 pipes going into the height corrector, but it appeaers to be a pipe 925mm long, heading to the anti sink valve. Does anyone know if this is the case? The other pipe shown on service box also goes to the anti sink valve, so does anyone know where the illusive 3rd pipe goes to?

Thanks very much. Dom.

Are you sure it's not full of muck Dom?

I say as one of the pipes - the one that drains back as the car lowers down - has a restrictor wire inside it and that would give the impression of being blocked...

You'd be best advised also, if it is a bit mucky, to Hydraflush as if one bit is then many bits will be and all will benefit from a good flushing clean

Interesting, do you know which of the pipes it is with the restrictor?

I have a feeling it was a self inflicted problem when we were struggling to remove the HC, I think it was poking around in the dirt on the HC, doh!

There was certainly a bunch of dirt in the end of the pipe which we've managed to remove using a pin, but we have a feeling there's more stuck inside hence the need to attempt to blow the muck out from the opposite end.

Thanks for looking!

The one you describe as full of muck is the pressure feed to the HC Dom, that's if it is on the side where there's one pipe going in.

Easiest way to flush it is to briefly run the engine to get some pressure up and let nature take it's course as it were. I warn you it'll be a bit messy and have an assistant ready to switch off as soon as job done..

One method to make it a bit cleaner would be to attach a length of plastic pipe to the ends of all the pipes and lead them all into a large catch jar..

Apologies about the slow reply, I've bought a couple of height corrector rebuild kits from citroen classics and have removed both the front height corrector (when this issue occured) and while we were there I had the Activa 'height corrector' off to clean out, both were pretty mucky internally, despite a recent hydraflushing. I can vouch for the fact that muck in the height corrector does not get removed when hydraflush is used, unfortunately...

Anyway - we managed to clean out the pipe in question by using some isopropyl alcohol, a short spray in the pipe and its coming out clean now, phew!

Good stuff Dom Glad you updated this as I hate it when threads are left dangling
