Coding to lower the ride height of rear airbags

[Asudevil]

I just saw in an old post where someone mentioned for those of us that have 3rd row seating in our E70's, which have airbags in the rear, that there is coding that can be done to lower the rear end of the X5. Since I just installed a new set of 20' 469m takeoff wheels and tires from a new F15, I'm EXTREMELY tempted to lower the rear end of my wife's 09' 4.8i just a tasteful amount in order to help close up the large gap left between the tire and the wheel well.

Can anyone please point me in the right direction on how to go about having this done? What all is involved by doing this? Is it a fairly expensive & complicated process? Does it change the ride quality very much? And also, does it increase wear and tear on any parts associated with the rear suspension? I'd prefer to not be forced into having to replace the airbags or any other parts shortly after making this mod.

If anyone here has done this, can I please see any pictures you may have to give me an idea of the outcome? I've also attached a picture of my wife's E70 after the wheels where installed to give you and idea of the gap I'm attempting to eliminate. Thanks in advance for any help!

I think it's a bad call to lower the rear of the X5 without touching the front. Your headlights will be blinding airplanes!
Best to get a lowering kit from H&R or similar. This way you drop both front and rear.
If you insist on dropping the rear only then visit Home Page and they will have what you're after for about $80.

You can adjust the headlights. Even when you lower the entire car you still have to raise the headlight a tad to illuminate the same area as it did before.

True you can adjust the headlights but that requires coding as well.
Best to use the links. You can adjust them to your liking. If you're not happy with the look just remove them and return to stock.

There are adjusting screws to adjust horizontally & vertically. It also doesn't require buying anything.

Whether you can adjust them or not, easy or not, getting back to the OP would you really want your X5 sitting lowered in the rear without adjusting the front?

I think he is looking to lower it like an inch so that it looks same as the front. I dont think he wants to slam the rear and leave the front stock. Not sure about coding, never heard of it.

I think if you read his post that is exactly what he wanted to do.

Thanks for all the awesome input guys. Yeah, I'm literally only wanting to lower the rear by maybe an inch or so to give it more of a leveled out look. What I have pictured in my head will be FAR from slammed. Just want a level look while most importantly, maintaining as close to a factory ride as possible.

Maybe fiddle with the sensor at rear suspension. Adjust linkage or use spacer under mounting point....
