It all depends on what was wrong with the original system to start with? If the bags, sensors and compressor are good then I would keep it on air suspension. Did you reset the system for testing before you converted up coils?

While in you're in that engine, replace the valve stem seals, it would suck if you got running good only to find out you have clouds of smoke coming out the exhaust. 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.

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...




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!!

!ouch: Excuse my ignorance, I had no idea that this was a 15 page thread since March! :imnew: Hahahahaha, nevertheless glad to hear that yours is running smoothly again, I have a little project brewing up on an 06 4.4 myself, some valve stem seals and 2 axle air suspension work. Hopefully it won't be too tedious and I look forward with working all of you in the future :D.

William, when you say you accidently reset the air suspension...did the compressor kick in or was it disconnected at this point? I wouldn't spend money on new bags (especially the front ones) before testing the whole system as it is first. This is the reason why so many of us have converted to coils...we made the "calculation" :)

Great work!!! Great pics.
When you remove th engine, you had the headers on, then install it without. Curious why? Was it easier that way?
When you put it back, did you lower in almost into position, put on the headers, fit the headers bolts to the exhaust pipe holes ?then lower it the rest of the way?
Thanks
