Same air compressor '05 4.4 and '06 4.8is?

[Clutch]

Hi all - my question is: are the air suspension compressors in a 2005 4.4 (rear only air springs) and my 2006 4.8is (all four corners air springs) the same? A quick visual inspection seems like they are. Mine in the '06 appears to be dead I would like to try and drop in the working '05 as a quick swap before moving on to other solutions as the numerous threads on the air suspension system suggest. Thanks for your comments and info!

4 corner air compressors ARE DIFFERENT PARTS than the rear only air compressors.

Ditto...a simple quick search of the parts database (like realoem.com or bmwfans.info) would reveal that they (EHC {single axle} & EHC II {dual axle}) have 2 different part nbrs...which means there's something different about them.

Thanks very much guys, I appreciate it. It should have dawned on me to check a parts supplier site. With the swap option out, I think I will try the rebuild kit that others have had success with. My compressor seems to be out of spec and is throwing the flag.
