confusion over maf identification

hi all

the car is a 1.8t 4x4 on a 02 plate arx engine.

i need to change the maf sensor as the present one is a bit erratic. the part number on the housing is 0 280 218 060 but if i put this into search engines it doesnt appear to be correct for my car.

eurocarparts, micks garage, misterauto, gsf  etc etc all quote 0 280 218 063 as being correct for this engine.any tech gurus out there?.

the car runs well except for the hiccups at high rpm which a lot of owners seem to experience .

i have worked my way through the usual suspects eg all breathers replaced with samco hose  plugs (genuine) coil packs (beru). throttle body clean. inlet  gaskets etc etc but cant get rid of this hiccup.i have no eml light on and it has been on vagcom with nothing seemingly amiss.

maf sensor next then n75 valve then give up and live with it.
