D4 EAS useless if ya use it

Hi have a D4 noticed if you raise car from access to offroad, then lower and try to raise again it took up to 2mins for front to reach height again or more if compressor overheated.
Dealer tried recalibration, no good ,tried new compressor ,no good Big Cry
Tried 3 other cars in showroom all the same, they contacted LRA, they said if 3 do it that is what they do now.
Was wondering if others have noticed if this is how it is, because it makes the car useless in offroad especially in the sand with the 40k\h speed height limit as if it goes down you're bogged before it will come back up.
Had a D3 before you could up & down a few times before it slowed (comp o\heat), so whats different ?
It really makes the car unfit for advertised use offroad and not at all a good improvement.
Cheers Ken

I just went from normal to off-road 3 times over a period of about 3 minutes a cycle, taking measurements and sensor voltage readings and moving the vehicle forwards and backwards a little during height changes. All was well, that is, until I lowered to access mode then tried to go back to off-road. I couldn't hear the compressor running so I suppose it was not, althought I haven't heard it before anyway. The compressor cover was quite cool with no external evidence of any heat being generated inside.
I suspect there's a problem.

Doesn't behave that differently from the D3 as far as I can tell. Up and down a couple of times, and then it slows down. I would regard it as operating as I would expect. I often leave the car in access height when parked, and it always goes straight up to normal height; the first D3 I had would give the "raising slowly" message frequently in the early days before the compressor fix.

Thanks Winger, I cannot see how LRAust, don't think its fault, they recalibrated and changed compressor, with no luck then found some others the same and decided thats how it must be. seems wrong answer.
Thanks again Ken
