X5 Air suspension and INPA help required plz
 

Can anyone help me please with an issue that I am having with my Air suspension on the rear of my car?


A few weeks ago I replaced the rear suspension air bags as they were leaking.
After replacing the Air Bags I checked all connections were tight and not leaking.


I put the fuses back in and i noticed that the air pump did not turn on to inflate the air bags.
I then used INPA to activate the air pump to inflate the air bags.


The issue I am having is that the Air Bags are not staying inflated and will deflate. This can be after 24hrs or straight away.


I think, that i may have messed up something using INPA software to inflate the airbags etc.


Has anyone had this experience before or does anyone have sufficient knowledge on using the INPA software that can assist me fix this issue?


Thank you

Make sure you aren't in transport or line mode or it will settle down onto the bump stops.....

Trust me, the Zamboni incident is still talked about on here [emoji1787] and by my wife [emoji28]

Thank you for your reply.
The car is in normal mode, not transport etc.


Zamboni incident ...??? sounds interesting

Do you have single or dual axle air suspension?

Single - Rear suspension


Thank you

Do you have DIS or ISTA to try a ride height calibration?

I have INPA and DIS installed on my old laptop. I have been using the INPA software to raise the suspension BUT, i am not sure what the actually measurements need to be to set the height etc.


My wheels are 19" and i think the height from the bottom of the rim to the arch should be 721 mm....

DIS has all of that internally. All you have to do it follow the procedure to measure the current height and it should audo adjust to the proper ride height. You can try INPA but never had luck with it.https://uploads.tapatalk-cdn.com/202...e1c28f937c.jpg

Using INPA I am able to adjust the height to the correct level. BUT, then over time, could be a few hours of driving the height drops and the pump fails to maintain the selected height.
So, i use INPA again to pump up t the correct height,



Previous to me changing the airbags the height was stable and never needed to be adjusted as the pump maintained the correct height.
