D4 MY11 Air Compressor Failed

Thanks for that Graeme , will give it a go. Looking at Trif's pictures of new and old compressor looks like the new one doesn't sit as low. I suppose that's good news. Now how to get mine to fail while under warranty!!

A "how to" to install the new type of compressor

RRSPORT.CO.UK • View topic - How To - AMK Suspension Compressor Replacement

Its good to know that the new pump can be fitted without upgrading the software.

For those interested there is some guy selling / auctioning refurbed D3/4 compressors on fleaBay. No association with them just trying to help out. I think the auction starts at $90 with a buy it now of 200 inc postage.

Graeme,
Did what you said and there was air coming out of the dryer although it didn't seem much.So does that mean that the pump is ok and the reason for the failure of the compressor must have been the breakdown of the beads in the dryer?

If the airflow can be stopped using your finger then there's obviously insufficient pressure. My current one produces virtually no pressure but because it produces enough pressure with the tyre pump attached to the inlet to avoid any faults, I expect its a worn-out valve rather than a worn-out piston/rings. I didn't bother to check its replacable exhaust valve because when I replaced my 1st compressor's exhaust valve it still failed to produce enough pressure. AFAIK there is no replacement kit for the inlet valve.

The new compressor model is noisier but more robust by the look of it.

Always get great service from the team at Berwick LR. Just thought that was what to expect from all LR service departments.
not the same but recently had a warning message of “suspension Failue”. Appended after I jacked the rear of the car to change right side tire - low pressure warning. No problem found with the tyre so put it back on. Low pressure warning continued and the Suspension Failure appeared. Car down on the stops. No adjustment available. Left the car for a couple of days and jacked it up again. Dash adjustment now available and message ‘gone’. Pressure warning changed to ‘Check all pressures”. On checking all pressures OK. Pressure warning disappeared. Electronics issue? Hoping it’s not a sign of more to come.
