Not sure if this is in the correct section.

Right. Last year we had the compressor overhauled (Wabco on a 2003 L322), basically our local mechanic fitted new O rings etc and the compressor was working fine.

Last week one of the front airbags failed and the RR spent a day or two with our mechanic. He fitted the new airbag but the compressor was struggling to lift the car.
He managed to source a replacement (Wabco) compressor from a breakers in Melksham and the car now is great! He said that the old compressor was only reaching 6 bar pressure where the replacement is up around 11 bar.

Now here is my question.

Is this old compressor worth anything?

Is it worth putting up on eBay as long as I stress that it may not be in full working order?

Or is it just scrap?
Any suggestions welcome!

I can put up some photos if necessary.

tested and working ones go for £50 quid, but if its not working at 11 bar, then sell it for parts on ebay, you might get £20 quid for it

I recently refurbished mine with a kit from this lovely fella in Scotland £25, rather than take a chance on a second hand one for £50

Andy you tube video -

the same Wabco compressor is used in many other cars, so someone might buy it for spares

The repair kit will fit all car manufacturers using the same Wabco air suspension compressor including:


Range rover L322 and Discovery 2 and Jaguar XJ8
Mercedes E-Class and Mercedes S-Class (compressor removal guide)
BMW X5
Audi A8/Q7 and Audi Allroad
VW Touareg
Porsche Cayenne

Wow...great info. I'll keep this in mind in case I ever need it. Thanks.

Bagpiping Andy's kit is brilliant! And so ids the 'how to' video....

+1 on Andy's kit, have just done mine last weekend. easy 10 minute job.

I was away for the past two weeks on holiday and had the dreaded air suspension inactive message come up. I cleared it with the GAP IID tool but it would recur. The error message was about not detecting a pressure change (I didn't note it exactly).

Luckily, unlike the P38A, the L322 doesn't drop to the bump stops when that happens so I was able to get the final 300+km home without issue.

Yesterday, I hunted out, amongst my spares, the bagpipingandy www.bagpipingandy.co.uk repair kit I bought back in July 2016 just in case I needed it (can you see the P38A ownership coming out in me?)

Replacing the piston ring was relatively easy. The cylinder bore didn't appear or feel worn but the old piston ring did look a bit sad. (I'll take a photo later.)

Here are a couple of pics which complement Andy's instructions:

Unclipping the wiring connector from the bodywork. Andy doesn't say how to do this but through a bit of experimenting I found one twisted the connector 45 degrees and it popped free of the mounting bracket. (Hmm, my fingernails look a bit grubby.)

my bagpipe overhaul is still going strong three years later - so as long as you get 10 to 11 bar, you will be fine

Good write-up p38arover, i did the same repair a few months ago coupled with a new to me (secondhand) center valve block and it's lifting great....i also got my kit from http://www.bagpipingandy.co.uk/ 2003 RR L322 4.4 ltr Auto Zambezi silver Custom paint

Hello . AM a new guy in this group. Got and L322 M/Y 06, which about a year ago was listing on one side (right hand side) if left unattended for some time. It was through Covid lockdwns I discovered this. So after all these lockdowns cease, I took it to my mechanic.

We made a plan and he recommended to me to overall the compressor, then replace of course the silicon bids in the dryer canister, then and we will see how it goes from there.

So I bought from the UK the overall kit for the compressor and the overall kit for the air dryer. I also bought the Valve Block O-ring repair kit.

When these arrived, I took them and the car to my mechanic. Same day he delivered the car back to me. Car was working fine, lifted a couple of times with no indication of overheating and no warnings whatsoever on the display. Let the car unattended as I was away for a couple of weeks. Came back car was listing again on the right hand side. Contacted the mechanic he said that we probably need to replace also the valve with the Part number RVH500050. I order it and it arrived in two days. Took the car back, and the mechanic delivered it back in 2 days.

Went to pick it up, 300m down the road "Suspension disabled" "Do not exceed 50KPH" messages on the display.

Ever since we get different messages like "Compressor overheat", "vehicle is lifting slowly" "suspension disabled" . Also there was a message for the RH rear height level sensor that the diags were not able to lets say "read" from.

I have read many good comments about the kit for the compressor overall. So I took the car to another mechanic. The second mechanic lowered and lifted the car 2 or 3 times consecutively and we got the same messages a s previously few lines up. He suggested complete compressor replacement...

So now am desperate. Is it the mechanics and they messed things up and they will not tell me the truth or the compressor overall went really bad, or is it something else. However out of all these, the car is not listing any more.

What are your opinions and / or advises lets say ? Honestly I feel like getting another overall kit and this time do it my own just to make sure and isolate whether or not this is a compressor thing !
