2010 RRS 3.0 TDV6 Suspension

The inconsistent height reductions suggests an air-spring leak but could still be a leaking valve in the valve block allowing pressure back into the main supply line, which is blocked by the exhaust valve. The valve blocks aren't particularly expensive especially compared with new air-springs or assemblies so in the absence of finding a leak in the air-spring, perhaps replace the valve block. If it doesn't cure the lowering then you have a spare front valve block which can be used in the rear, albeit with faster raising than usual due to the larger orifice in the front valve block than the rear catering for more front weight.

Thanks Graeme, I'm going to 'see how it goes' over the next few months as its minor at this stage. If the valve block is changed do you need to recalibrate the suspension?

No calibration required for a change in valve block. Indeed calibration is not required if the air-spring assemblies are replaced.

Feeling your pain woody. Got quoted 2k for a new pump on my 2012 with only 60kms on it.

Mine just seems to be having issue lowering to access. Few fault codes apparently point to slow to re fill and exhaust valve problem. So like you I'm just going to leave it in normal mode and live with it for a while as I had to replace rotors and pads today and control arms soon.

My rangie experience starting to hurt.

Iv been told to only replace with an AMK compressor, you can get them for around $1200, if you are willing to DIY you could save some dollars there, apparently it's not too hard. I'll be doing my own when it's time. They are expensive, but what a weapon of a machine they are!!

Be sure to update the suspension ecu with the software for the AMK.
