I have the X164 Chassis and wanted to look at replacing the Airmatic Air pump. No one thus far have been able to tell me and if they have fitted the X166 Air pump to the X164. The reason is price. in some parts its nearly 200 buck more for the x164 as a pose for the x166. Looking at the parts the shapes is the same, the electrical plug connectors are the same so can they be interchangeable and am i missing anything? Thank you! X164 Airmatic Pump.
Looking at the price points for each I am not finding the $200 delta you’re talking about. They’re about $125 for chinesium on Amazon or $375 for an arnott pump with a lifetime warranty, regardless of application.
but do let us know if you get any malfunction messages.

Yeah, if the brackets are different they can probably just be swapped from one compressor to the other. It is possible the connectors are different, either physically or the orientation of the wires inside. In other words, the DC might be flipped on either or both of the connectors.
I doubt the compressor is capable of making the system throw codes, short of simply not pumping correctly. It has just two circuits, one power for the pump and the other the vent valve. All the system does is send voltage. It may monitor the current flow, like it does with various bulbs. But that seems to be a stretch, though I try to never underestimate MB's stretching capability.
To the OP: Whatever you install, I would make sure you get one of the OEM manufacturer pumps, that is, AMK (for the x164 at least). We don't have a lot of data points, but at least: no confirmation of a Chinesium pump lasting, confirmation of Chinesium pumps failing ridiculously early, and OEM pumps lasting ridiculous lengths of time. If you get an Arnott pump and it is Chinesium, I would recommend also getting a generic Chinese one to have as a backup while you wait for the replacements from Arnott to arrive.
As noted above, you're looking at different manufacturer's of the air pump so you're not comparing correctly. For example, the Bilstein, through RockAuto (also carries Arnott) is about $400 for both the X164 and X166 - a $200 air pump is probably going to a one-time use pump
Thank you Dennis for the info. I still haven’t found anyone who's actually done it. Successfully fitting an x166 air pump to the 164 regardless of make or brand of airmatic pump and I am hoping someone here has done that. X fingers of course.
Seller "partscontainer" on Ebay has the AMK A1991 for $377. That is the same pump as the Bilstein.
Arnott used to put their sticker on the A1991 but then they transitioned to Chinese pumps. I installed one; didn't last 20k miles. "single use" lol is not far off the mark
partscontainer also sells the old Arnott, but they shipped me the new one instead, and when I complained they just argued argued argued. However, it was no problem shipping it back, and they shipped me the apparently genuine A1991 no problem.
But... I think it's sort of a moot point, isn't it? If the same (quality) brand is the same price regardless of platform, wouldn't you just buy the one for the X164?
OP it's your time, so it's yours to spend as you wish. Max already answered the question; any price difference you are seeing is because you're looking at two different tiers of pump, not some anomaly between the two chassis.
Of course, if you find a x166 AMK pump for $200 less, why not try it? Just make damn sure you get shipped a real AMK, without the precious Made in China sticker on it.
You've gotten a lot of replies because we love discussing Airmatic here. Ain't that right, fellas?
Seriously, it's a fun system to play with when you get it under control. I think I even mentioned changing brackets because there appears to be one pump, many different mounting configurations.
P.S. My two Bilstein rear air springs showed up from Rock Auto. Sure 'nuff, they're marked 13.5 bar. Plan is, I'll check the rear Arnotts for leaks, and when they start throwing stoner spit, I'll pull, swap in the Bilsteins, and sell the new Arnotts I receive in return.
