Airmatic compressor

Is A 211 320 03 04 the same as A 211 320 03 04 80?
From what I can tell the -80 suffix is a remanufactured unit, although the first one is noted as may be sold as reconditioned.
Are there other differences?
Sounds like WABCO is OEM.
FCP Euro is all sold out.

Yes.
No.
I installed a new WABCO sourced from Arnott.

Thanks, Birdwell.
I thought it was interesting there's a note in the service notes to also replace the compressor relay, part A 002 542 23 19. Seems a bit overkill, but then again we are MB owners.
May your bird be well.
