Is the procedure different for removing the air suspension compressor from a W12 D3? The procedures I found online say to drop the belly pan and remove the 3 10mm bolts and remove the compressor. I can't even see my compressor from underneath and there is a secondary air injection pump for the engine where the compressor should be. I need to do a piston ring replacement on the pump, can anybody post the procedures for me please? Thanks a lot.

Thanks for that! That appears to be for the V8 models. From what I can tell the W12 uses two secondary air injection pumps that are in the way and must be removed first, but Mitchell repair data says to remove the front bumper and headlight as well, I am hoping that's not necessary for the W12 pump
