Thread: Multiple Suspnsion Warning Lights

Typically a weak compressor is indicated when the amber light occurs a little while after driving off. Once the vehicle is up to height the reservoir is replenished but if the reservoir pressure doesn't increase quickly enough, a fault is registered. However if a selected height can't be maintained then the warning light will go red.

Thanks Greame, thats why I am wondering if I have a different problem or a mixed problem.

Thanks i have the same problem , light does not always come on.
I have the old compressor so it looks like a new one is needed - only had the car 3 months and it is 08 wil 85k on it ..
Has any one rebuilt one using kits out of the uk ??
Need LCA's as well but knew that when we got it .

Same for me, 09 with 80,000k's and original old style compressor. I did my LCAs at about 60k.

Possibly points to the dryer unit needing attention - rebuild kit. Would be interesting to understand the logged faults, they'll probably point you to a low pressure state (as Graeme has said).

I was faced with the compressor question shortly after the AMK compressor was released (noisy, slow, no dash faults but occasional logged fault) - as my Hitachi had already had the dryer serviced once and something else done to it (which I forget) earlier, I decided to bite the bullet and move to the AMK (my Hitachi was 6-7 years old at that time and the vehicle had done around 120,000km).

The AMK is a big improvement, smoother, quieter and quicker than I ever remember the Hitachi being (could be rose colour glasses, who knows). I've had the AMK in for about 18 months and it's going great.

I think I will also just bite the bullet and get the new compressor. I do quite a bit of touring and don't want to be let down in the middle of nowhere.

Also get the s/w update that sets a lower reservoir pressure. It stops the compressor from having to work so hard even though it may run more often.

Yep, when mine was changed it worked fine, but a review of logs indicated exhaust valve faults (occasional) so off to the dealer for a SW update ($66, 15 minutes). IIDTool is now capable of doing this SW update with the latest firmware version.
