Do any of you have any advice for replacing the compressor for the air suspension on the sportbrake (x250)?

Thanks
Phil

Not seen anyone try that on an XF, but I wonder if it is the same as used on LR and RR vehicles, in which case there are plenty of hints, tips and tricks on their forums. They apparently fail regularly on the likes of Discos and RRSs.

Are they electrically powered or direct off the engine/belt drive?

They're electrically powered, and mounted under the floor where you'd expect a spare wheel to go covered by a foam cover, there are two cables leading to the compressor, think one is for the compressor itself, and one if for a vent valve on the drier which is attached to it, it's suspended under a plastic tray which has the control valve with four pipes fitted on top, two are thin pipes which disappear into the wiring harness, and presumably go the left and right rear air springs, and one that goes to the compressor, and another which goes to a small pressure tank, I'm wondering it it's possible to take the compressor out without disconnecting the control valve so hopefully the car won't sink all the way down but looks like it needs to come straight up and inch or to to clear a bolt.
For that matter will it automatically inflate just by running the engine for a bit as generally only used to here the pump after driving a couple of mins?

Hi PeteA,

Thanks, that's some great info, so looks like you have to disconnect the pipes that lead to the suspension units to get it out. Do you by any chance have the 204-05 section on depressurising and re-pressurising the system?
Also it mentions that new air line connectors must be installed, so any info on those would be handy, as maybe they need a special tool to crimp or remove too.

Looks like the tie down rail that runs along the boot floor, and it's support bracket need to come out too, neat the way they just disappear between steps 5 and 6 :)

Thanks PeteA, ordered one of those a few hours ago :) hoping it will have all the info, just trying to figure out if it's within my capabilities, so I can decide if I should order the bits, working from home at the moment so no desperate rush, and don't fancy risking a trip to the dealers under current circumstances. Looks like they're out of stock with jaguar too!

Hi Phil, I broke a 2012 sportbrake as a donor car and I have the assembly number 4 that you refer to in #5 post, is it the complete assembly you need or just the compressor motor that you need?

Hi Dan,
just the compressor AFAIK, and guess I should replace the relay too ( think it's in the main fusebox), can't think why I wouldn't be able to bolt it on the same plastic plate the old one comes off. Still not sure if I can depressurise and re-pressurise the system or if I'd need dealer diagnostics to do that, and if I'd have to support the car while it's empty or it's ok to let it go all the way down.

The donor car was a non runner so I wasn't able to test it but the system stayed pressurized for maybe six weeks until I removed the unit. It certainly didn't seem like very high pressure, maybe 20psi? and the suspension just sank down to the bumpstops so not real need to support the car. Not sure on re pressurization but it seems a very simple system.

Hi Phil, I don't have the relay, I'll see if I can power up the compressor tomorrow and check out postage rates, a site on ebay did say that the major cause of failure was air leaks on either the pipes or rear suspension struts causing the compressor to fail through overwork. It might be a good idea to check for leaks after replacement.

Thanks, think leaving it parked bar moving it occasionally to rotate the tires for a few weeks has allowed it to seize, car is still at normal height though so don't think there can be any leaks. But I suppose take the relay out for a couple of days afterwards and check it doesn't sink is probably good advice.

Hi Phil, no luck I'm afraid, I connected the assembly to a battery, it struggled briefly and then gave up. Maybe you're right about lack of use allowing it seize. There was still plenty of pressure in the air tank, which I released in case the pump was struggling against the stored pressure.Good Luck

As I said earlier, probably all you need to know about this air compressor will be on the LR/RR forums.

Oh hello what's this, the air suspension compressor can fail? 😮

I'll add it to my list.
