I will check the linkage first, thank you.

 

If you have INPA you can test your lights manually. Also it will tell you if anything is wrong

 

That is good; any instruction for that ?

Thanks.

I can open up INPA and write down instructions. When I did it I just played with it until I got to where I needed.

 

I would appreciate if you could provide the instruction.

Thanks.

 

You will have to go into the E60 menu then click on Body. Once on Body look to the right and you should have a selection for adaptive lift control. Click on it and from there you can test your light up and down left to right.

 

Get it, thank you so much.

 

it might be the leveling sensor

 

Do you know how to check sensor ?

Thanks.

 

If you have a reader that reads the output you can check it that way or just physically check by looking under you car
