thanks for answering.

i was thinking along the lines of that.
Here is the problem. I had my tires exchanges earlier and when they lifted the car they placed rubber blocks between the chassis and the lifting machine in order to lift it.
The front left block was placed under that tank. So 1/4 of the cars weight, probably more, was resting on the tank. They said everything is fine etc, its a part from the chassis they always do it like this (that garage has had my LR4 there a couple times otherwise the closest car the exchanged tires on was a RR sport), i didn't believe that so I started taking pictures like mad.

That has paid out now as the air suspension is no longer functional.
After lots of playing with the up and down buttons it now no longer does anything. Its in access height, the screens and indicators show it is in off road height which is what I selected. The system said it needs to cool down after pressing the up button once. I let it cool down for 2 hours. Tried again. Nothing. It managed to get the back suspension up now and then by maybe 1-2cm.
So they destroyed something the idiots. I told them its not part of the chassis. He was like "oh yeah, its STEEL supposed to be there, no problem at all."

Also when the wheels where fixed again the car was lowered, front suspension went down to normal level once the wheels touched the floor and the weight of the car forced the suspension to how it always is. However the rear did not go down. It was higher then it is in super extended mode. We drove it out, played with the up and down buttons and it eventually lowered itself.
Could that be linked aswell?

1st pic, rear suspension after lowering, front was at normal level (10cm between wheel and wheel cover thing)
2nd pic, placements of blocks.

thank you

I think you may have dodged a bullet there by taking the photos. They clearly have no idea what they are doing if "they always do it like that".

It's certainly not an approved jacking point, and certainly not a part of the chassis. Someone who knows much more about the air suspension system than I do will be along to give you an idea of what it could have damaged.

Yeah I really have. Lets hope they have good insurance They should technically HAVE to pay for the damages.
I was suspicious, so i took photos. Started doing that with everything. The state of rental equipment before etc. I was ripped off twice before. Never happening again!

Exactly, but you know he said its made of STEEL so obviously its all right :P
"Someone will be along to give you an idea of what it could have damaged." what do you mean by this? Someone will write here? Sorry for not understanding.

Thank you for your help

The first thing to do is grab the manual and find the 'Approved" lift/jacking points. That will give you an idea, and it will state any warnings regarding what can happen using non approved methods. I suspect lifting in that manner may have damaged the height sensors which is what is causing the suspension to malfuction. The control is not recieving any data re heights so it is ignoring.

Firstly, I would suggest that you request a moderator move this thread to the D3/D4/RRS forum (by clicking on the red triangular on the right hand side of any post), and then some of the members who know the air suspension system inside out will be more likely to see, read and give advice on the potential damage caused.

I have read those several times. Sadly the warnings in there are very basic.

Interesting thank you. Is that where the sensors are located?
How can you / anybody explain why the systems overheats very quickely, quicker then usual, and that I cant hear the air being pushed into the suspension. Usually you can hear it, its just dead silent now.
Also does the rear suspension not lowering after the car was lowered off the lifting equipment mean anything?? normal for the car or a problem?
Taking the car to the dealer in the next days but I need to tell the shop something, hence why I asked about the tank in the first place.

Thank you for your help

btw: I have requested to move this thread.

If one part of the garage lift went on the air tank - where did the other lifting arm go - under the air compressor?? If so maybe that is why you have issues.
