Took a little time to get the supplier(s) of those things grabbed by the short hairs, it would appear. Thanks for info.

I've had the compressor replaced twice under warranty. In looking at the EPC-Net, I see there have been two upgrades in the P/N since my last one.

I wonder if I can get an upgrade done under warranty to the latest iteration? The current one still seems to still be working at 18,500 miles since it was replaced and a total of 43,500 miles on the car.

Just had this done at 48,500 miles. Even though the AirMatic seemed to be working fine, the dealer told me I didn't have the most up to date compressor and relay; so he replaced them under warranty on this Service Campaign.

Hopefully, this ends all future troubles. Warranty is almost done, and that compressor is not inexpensive!

Dutch - Maybe you know the answer to this question: I just had my '08 Gl320 CDI into the shop for door handle replacement and the SA told me there were no outstanding campaigns against the vehicle. My airmatic system has never acted up nor has any shop work ever been done on it. It, like yours, is getting toward the end of the warranty. Is there any way to find out if the this compressor campaign is applicable to my car (outside of asking the dealer again, of course)? I'd hate to let a chance to update the airmatic 'get away'!
Thanks

Here's the applicable Service campaign Info:

I'm pretty sure that you have to bring it in with a "It doesn't seem to be acting right. Please check it out." or some similar complaint to get their attention. That's what I did.

I also had them put the latest transmission flash on it; and this seems to have finally resolved the hard 2->1 downshifts.
