I'm here in Chicago, and I have an appointment with a BMW dealership here. They seem confident that they can get this done for me. I'll let you guys know what happens on Monday. Fingers crossed!

If you need it done, I have a shop that can do it for you without a hitch.

I thank all who have assisted me in this project and you know who you are. But, I have to give the blue ribbon to Killcrap. That Mofo knows what he is doing.LOL without him I would have been unable to determine the new SA code to recode the computer for no warning. AFter receiving the new code I was fully equipped with twinspoppa's GT1 v4.3(Thanks you for letting me use your beautiful machine). The whole process took about 20 minutes and all was well after the recoding. The steps were very straight forward and easier than installing swaybars and well worth the dyas of effort to sort things out before it all went down. My advice is to contact Killcrap for your new SA code since every X5 is different and then get yourself to a gt1 and follow this easy procedure:
Select CODERIUNG/ZCSFA
Select E53
Select Recode
Select IKE
input VIN/Milage if prompted.
When asked to change SA, do so with the new code.

Then do the same with EWS
and recode the ZKE/GM module, and the LCM module.

*This procedure has been brought to you from the expertise of KILLCRAP
Thanks dude!!!!!!

Laurel BMW in Westmont, IL (suburban Chicago) succeeded in the reprogramming procedure. Their lead tech is apparently quite sharp.

Killcrap also says that Perillo BMW in the City of Chicago is also capable of getting the job done.

So the total cost to have the rear self leveling retrofitted with coil springs was $735. $400 for parts, $205 for an indy to install, and $135 for the dealership to reprogram.

FWIW, not all BMW dealerships are created equal. The dealership near my home in Springfield, MO had the X5 for a full week and finally threw in the towel (thankfully at no charge to me). Laurel BMW had my car for a full day, since they had to wait for a "service order" from BMW headquarters in order to do the job. Killcrap could probably corroborate if that is standard procedure or not.

the technican had to request the ZCS code from BMW North America. "service order" is the incorrect name. On E53, the car has ZCS coding. The newer cars have "vehicle order" which is much simplier to modify. The vehicleorder/zcs is loaded the same way. But requires a IBAC code from BMW to import this code, the older systems such as CIP/Progman and DisV44 can load the vehicle order without this IBAC code. If you would of came downtown at Perillo, they wouldnt need to ask BMW NA for this code, as they have the capability to generate the modified ZCS code. You would of been done in less than 5 mintues. While your coffee was still being made.

Why didnt you ask Laurel about it before you left?
