been here at my local indy for a few day's but we can not solve this problem
started out with a lower rear right, so wanted to have it calibrated.
car moved his ass up in the air and wouldnt come down.
after some juggeling with the software ( dont know what computer he is using) front came up and one blew up almost in my face..... replaced both front supensions and he had an other indy with another computer comming in.
car went down on his belly and never raised again...
all lights on the dash (4 leds from suspension) are flashing and saying air suspension default.
compressor is good.
no fault codes show up.

anyone got an idea? cars on the side;

I know that on my car the compressor would not start until I had done the steering recalibration.... Turn all the way left then all the way right. Previously..

yeah, I know. did that. Called the stealership and it might have to do something with a fault code from the trasfer box. Don''t know why but that is what they said. indy is gonna look into it tonight, otherwise it's off to the Stealership tomorrow... cars on the side;

I had a guy come in two weeks ago. A local garage had used a lesser diagnostic system in trying to calibrate the RLM. This caused the front LH airspring to explode. We connected with T4 and did the calibration routine several times to get it right.

What size rims are fitted to the vehicle?

Read my thread - http://www.fullfatrr.com/forum/topic18252.html

20" rims. My left front also exploded. Replaced both front springs and after that they tried 3 differend computers on it but nothing worked. now its at the dealer who can also not log into the EAS ECU. so they say it needs to be replaced. Personally I don't think that is the cause but we will see tomorrow. cars on the side;

@rs2000custom Read your post, with one of the computers they used the did get the backside back down. So I dont know if that is the same issue but will keep it in mind. cars on the side;

The 20" should calibrate fine with T4. It tends to be a problem because T4 will only calibrate on the standard sizes.

Tell them to use the Range Rover CD with their T4 - CD DJLO20. I expect they haven't broken out the T4 unit for a while.

they have some red unit, witch connects with a wireless device. cars on the side;

Probably a Snap-On Modus or something. You'd be better taking it to a dealership to do properly with T4. I've only experience with the Utrecht dealership, but they were pretty good at this sort of thing.

It is at the dealership right now. that was the comp ( or something alike) my indy was using. cars on the side;

Dealer can also not access my EAS ECU. so it will be replaced 2morrow cars on the side;

Um, rim size shouldn't make any difference as long as the correct sized tyres are fitted, distance between hub centre and ground should be the same. Will of course depend on what measurements you take when calibrating

I did a chart:
