I was thinking the same thing!! I liked having the Air Ride when I first got the X, but never got a chance to use it after the engine rebuild... Now the trans EGS module program issue that is still keeping the X down... I'll calibrate everything after I check all the height sensors... I think one of them might be off a little...

I needed to move the X around outside since my garage is occupied with a larger project (that is now getting tossed due to the weather)... SOOOO, I did the swap prior to getting the coding working... Now that the coding is going, I triggered something in the Air Ride module using INPA when I was trying to get the EGS into SPORT mode so it would talk to the TCM...

I think I'll swap back... And with new front bags too... Maybe all four if the rear aren't too expensive... The front need to be new regardless...

As for the air suspension, if only you had a good diagnostic tool like a snap on or autel maxisys but those are pricey. First thing I always do is hook it up to the scanner check the codes and then force the compressor to run to see if it works. If it doesn't it's burned and you need a new compressor, if it does then you know the compressor works and you have some other issue. Could be lucky and just do a reset of the system or it could possibly be the module. If it does run check for leaks in the hoses, bags, and the aluminum air storage container. Fortunately the rear bags are cheap, aftermarket from eBay starting at around 55 bucks or so. I would go with arnott rather than genuine Bmw. The front ones are more pricey. Anyways good luck with that and let us know with any questions, I've fixed a lot of X5 air suspensions both 2 axle and single axle. They are by far ALOT easier than benz suspension.

Yes!! All great points... I did a complete tear down of the motor with new bearings and block conditioning... Heads were completely torn down and rebuilt with all new seals and gaskets... I even made my own bench-mounted valve spring compressor for this motor... It was pretty, sitting on the engine stand, right before it was to get installed... Looked like new, out of the box...

I got INPA, NCS Expert, and WinKFS to work in attempts to get my EGS trans module programmed (still working on that)... I got all this Air Ride working AFTER I did the coil swap.... I must have reset the Air Ride while I talking to the other modules in the vehicle... I have heard great things about Arnott... I did plan on going that route and will probably do all four corners...

Well, that is two in favor of swapping back... Three, if you count me too... So, I think I will swap back, but keep the parts on hand in event I need to keep it on the road in a hurry...

Thanks all!!! Gotta update my photobucket!! Out of room for more pictures...

Cheers for now!!
