Reply With QuoteExtended height only occurs if the vehicle appears to be grounded, ie some wheels are spinning. If wheels are bouncing and loosing traction a lot due to useless shocks then that could be causing the system to think that the vehicle is partly stuck.

I've just finished a four week trip to the tip and back - I'll do a bit of a write up separately if anyone is interested - but I started to suffer some strange behaviours from the air suspension towards the end of the trip.
While on the old coach road the car went into extended offroad height multiple times 1) by itself 2) on relatively tame sections of the track (certainly done far worse without extended height), that we weren't stuck on and were making fairly easy progress. After doing this a few times I plugged in the IID tool, no EAS faults but the compressor was cooking at 130 degrees C.
in regards to 1) - is this normal behaviour for the car to go into extended height by itself and I just haven't been paying attention? I thought the car *offered* extended offroad height but I had to press the brake and hold the raise/up switch for 3 seconds to go into it? At least that's what I thought I'd seen in the past. I've never had the car go into extended height by itself before this trip. The first time was actually when I was floating it across Nolans.
in regards to 2) I'm suspecting, and would love to hear people's thoughts, that my shocks are cooked after the corrugations on the PDR and it was perhaps contributing to some poor traction on later tracks leading the car to think it needed extended height despite making progress.

SubscriberAgreed. I’m wondering if a new set of shocks might fix the problem, but I’m not a mechanic

SubscriberI think your height sensors may need recalibrating before you do anything else, they have been known to lose their reference point over time, and severe corrugations don't help.

Maybe some mounting screws have worked loose.

unlikely to be a sensor problem. I've measure all the corners and they're unchanged. it has no problem raising to off road and lowering to access. The problem was when on a track it frequently went into extended height despite not being grounded or stuck and my thinking is that because the shocks are cooked after the corrugations, it would get a little bit of a bounce causing some wheel slip and tricking the terrain/suspension ECUs into thinking it was stuck or grounded.
is it normal for it to go into extended offroad hight automatically when grounded. I aways thought I had to hold the raise button for 3 seconds in these situations but maybe I haven't been paying attention. usually when I'm in these situations I'm concentrating on not rolling the car and the message flashes up on the dash and dissapears before I have a chance to change my underwear and see it!

Correct,extended off road height has to be selected by the driver,following a message on the dash,and it drops off at around 8 Km/hr from memory.Originally Posted by Macadamia
Can’t help with your issue,but there are loads of creek crossings up there so maybe water has got into something?
Even a plug in the wiring,if so it should eventually dry out hopefully before any corrosion starts.

Extended height is automatic, but once in extended mode super-extended mode is enabled by holding the raise button while pressing the brake pedal for 3 seconds.

Others including myself are calling ‘off road height’,the normal off road height,drops down automatically at around 50Km/hr,initiated by a switch on the center console.
Extended being ‘off road height’extended higher,driver initiated by following dash read out,as Graeme said,hold button down and brake pedal,and drops down automatically at around 8 Km/hr.
I think that is what the OP means.
But maybe not.

Extended mode is an automatic additional height that can occur in any height mode from access to off-road if the vehicle fails to move appropriately while wheels are turning. When extended mode occurs while in off-road height mode, the driver has the option to go to super-extended height. Extended mode raises the vehicle a little from the current height mode rather than to a set height.
