Air Suspension Calibration

[Dronkailp]

I also wanted to lower the suspension, the same problem as others. During the preparation (check) for calibration, the machine produces a suspension error that disappears only after you have driven for a while. I repeated it three times, the same thing every time. Has anyone figured out what the problem is?

Trying to figure out why I am having an issue with the calibration. Should the “write calibration” button activate the change? My button appears to be non responsive. The suspension doesn’t change after I click it, and the button has no visual change when I hover over / click on it. I can press close, but the write calibration button doesn’t do anything, and my height doesn’t adjust. In order to access this menu again, I need to disconnect and drive the car up to 32mph each time.

But the height remains the same that it was before.

Any help would be appreciated.

Solved the above. The issue was the half mm measurements. Need to just round up or down in order to have it execute.

Still playing around with it, but this is 25mm drop all around, Ride height in Polestar Mode.

Is it possible to edit riding height differently on profiles? Like rise on constant awd and lower on performance mode? Are there any information available for the min/max range of the adjustment without hurting anything?

Hi All, i have a question related with the air suspension settings - on the Volvo repair procedures for the V90, when it comes to replacing the air springs for those with air suspension, it mentions a section where before removing the springs you must deflate them using VIDA.

Is this something that can be done with OrBit as well?

Just bumping this question if anyone knows the answer

Hello,

There is nothing really that needs to be done additionally than clicking on the center menu at the "locking & suspension" section the suspension to service mode.

In the last 2 days I have now done overhaul to my XC90 air compressor(changed the decissant/dryer granules), changed the rear shock absorbers and front air struts. All was done by only clicking the center for service or deactivated mode and done. Obvioisly between each phase I let the car to fill the system again to not have it completely empty. Each unit is filled separately via the block valve so it will only empty that section if you change something and therefore very limited amount of air is running out
With compressor removal it will empty the tanks so that is a bit more air coming oit and when it starts to refill it will take aroind 4 compressor runs before the system is full again.

With the suspension part you just have to bear in mind that once you are done with the work and lowering the car just dont lower it all the way before you start the car and take the tick off from service mode. The system will automatically fill the bellow and then gradually lower completely.

At least mine is now all done and perfectly smooth ride again (I had quite a bit of noise coming from passenger side front). Now I will soon also chang the rear bags and the complete system is then almost new. Here in Sweden it is cheap to buy used parts which have only 100km driven so this is what I am usually doing as then I have OEM pieces.

Hi, thanks for your reply!
I actually attempted to replace the rear (and only) air springs on my V90 but it seems that without being able to deflate them, they're just too extended to be able to remove without having to pull out the whole suspension setup (or at least a huge chunk of it).

I turned the car of and disabled the suspension auto adjustment, before lifting it on the scissor lift. I even considered if there perhaps is a guaranteed way of making the system "think" the air springs should be emptied, but haven't come across any. Bit stuck here not knowing what to do, sadly (Unfortunately for this scenario i'm based in the EU so no access to VIDA subscription either).

Hi, what you have to do is to disconnect the air supply hose from the air bellow top and release the air (slowly). Once that is done then by hands you are able to release the bellow by compressing by hands. For your car you can use the arnott guidance video in youtube.

Thanks, I was concerned there might be some kind of fancy valve or sth that would only work if electronically released, but now that I think about it, that's stupid cause there's only an air pipe going into them

Looks great!  What settings did you go with?  Did you adjust the trim settings?    Does it drop even further when you have the easy entry/exit turned on?
I keep messing with the numbers but my rear is still sitting a little low.   is there way to reset back to the original numbers?

Hello, 

Under the Levelling sensors there are some strange options.
Does anyone know why there are 2 options for SUM function which are identical? 07SUM, front Right, front Left, rear Right, rear Left and then 09SUM, front Right, front Left, rear Right, rear Left? What is the difference between 07 and 09? Mine is set to 09 from factory.
On the same place it also have some VDDM under 06 and 08 - what is the VDDM? 
I have some strange thing happening - when doing calibration then all goes fine and it adjusts everything, but afterwards when park the car and leave it, it raises the right side rear almost 1.5cm higher (even when the car is on a levelled surface.

What I cant figure out is why the system gives Suspenaion failure alarm when performing the calibration on the dashboard, but I guess thats how it is doing it.

Right so thought  I would share my experience with factory air suspension and deleting/coding it out.

I have a 2017 S90 T6 with the factory rear air, steel front and 4C/DCC shocks package.

I have fitted aftermarket air suspension to mine, I had made a set of DCC cancellers to fool the car into thinking it still had factory shocks up front (I reused the rear oem dampers, so left them plugged in).

I first tested this by unplugging the dampers, giving an instant suspension service fault, then plugging in the cancellers in front and leaving rears connected, zero faults like this for about 1 month of daily driving so i knew it was good.

I disconnected the height sensors from the control arms (it has 4, 1 per corner like full air cars) but left them plugged in and locked them to factory level to prevent headlight level errors when airing the car out completely.

This meant the rear was still trying to self level though when the doors were opened or unlocked etc, even though i had the sensors locked within mm of factory heights, leading to compressor running too long as there was no factory bags to fill up so tank would empty through the factory air lines.

So i removed the air compressor fuse, and the car only threw a basic suspension service required fault after a short time driving but otherwise worked great. 

I finally got my Orbit to work and be able to code to the car after some issues, so i thought to try tackle coding out the factory system. This is where it went a lil south for me haha

I started by clearing all DTC's and then changing blocks 58, 59 and 60 to 01, and checked that 237 was set to 01 as well which is was on the factory config

This threw the car into disarray, with the suspension failure fault now logged, headlight range error, as well as ESC temporarily disabled, Handbrake unavailable, TPMS error to boot.

So i tried to reset everything back to OEM to start again, and the SUM is now default and has to be recalibrated. Which i tried to do after putting all the factory components back, it fails at the Level Input stage every time. I need to drive the car a short distance to reset the SUM and get the compressor refilling the tank etc but this is a lil bit hazardous due to the bags being empty. This means ideally I need to track down VIDA to be able to refill the suspension to recalibrate everything, which is a nightmare for me to do locally without an expensive dealer visit. I am hoping that Orbit can have this option added to ECU tools.

So i refitted the aftermarket suspension components and set only block 60 to 01 to code out the level sensors which allowed the other errors to be removed such as the headlight errors, so i know that works and narrows down the fault to the SUM module coding out, there must be something else i am missing on the components side in order for the car to think it is a factory steel suspension car. I have tried setting 60 to a different VDDM 2 sensor mode but also no luck.

so it currently has block 58 and 59 as 02 and 60 as 01, with the only error now on dash being the suspension failure error, which although super annoying I can at least drive around and live with until i find a working solution.

I will attempt to try again but it is my daily so i have to plan accordingly. It doesn't take too long to convert back to factory components luckily.

I am wondering if i could find a steel suspension config from an S90 to compare to my S90 to see exactly where the differences are, locally here in South Africa we dont have any S90's so its not something i can easily do.

So long story short it is not just a case of setting 58,59,60 and 237 to 01 or combinations of different settings
