A.I.R. system = PCV valve??? '01 W220
'01 S500. it seems these cars don't have a PCV valve, but some kind of air pump system called A.I.R. -- is this true? it also appears that there's an A.I.R. pump "check valve" -- would this be analogous to the PCV valve?? does anyone know how to replace it?
thanks!
thanks!
