What is the use of that thing?

It damps the mass....
If your talking about the doughnut things on the axles, they are supposed to reduce vibration through the drivetrain.

OK I believed that it has something to do with the air suspension. The one that sense when the chassis is stuck when off roading.

I suggest you have another think then, because they are there to counteract axle wind up as power is applied or taken off. They basically in laymans terms, stop the nose of the diff from flopping up and down like a whippets dick.

I thought that was called the driver - usually cos the car is not going anywhere when the go pedal is pushed :doh:

It's a valid question. The P38 does apparently contain some kind of mechanism whereby it realises it is beached and tells the EAS to extend just a little bit further.
No idea how it knows it's in that situation though.

Maybe it does, but it certainly ain't those big round mass balances that tell it about it. How much further does it extend when your beached in high mode. Presumably until you hear a pop as a bag blows out. Or it pulls the shockers off their mountings. When it can't go any higher it can't go any higher. No matter how stuck it is.

I do not think the EAS has any 'higher' settings than the high mode - so how could it go any further...

The manual says:
1" low
2.6" access
1.6 above standard High
2.75 above standard Extended profile
Extended ride height
This position is achieved if chassis is grounded
leaving wheel or wheels unsupported. Initial ECU
reaction is to lower (deflate) affected springs. After a
timed period the ECU detects no height change, it
therefore reinflates springs to extended profile in an
attempt to regain traction. The position will be held for
10 minutes, after which time the vehicle will
automatically return to standard ride height.
Pressing the down switch will lower vehicle 20 mm to
high profile.
If vehicle speed exceeds 56 km/h (35 mph) the
vehicle will immediately lower to standard ride height.
This speed could be achieved, for example, by
wheelspin.
OK so it is not a sensor. jejeje

No it isn't, it is hard to imagine how a round rubber mounted metal disc could send any sort of a signal to the EAS ECU. Nobody is arguing about EAS trying to gain traction when chassis is grounded. But linking the mass balance to this is like saying the sump plug measures oil level.

What? You mean it doesn't?

No it just stops oil from leaking onto your drive. The copper washer often fitted to sump plugs is there for the sole purpose of falling off into your old oil.
