Bought a MK4 Golf 1.6 16v last month for the wife. I thought something in the engine bay didn't seem right but i wasn't sure what.
Anyway, changed all the filters bit by bit with the air filter to do tonight. Go to do it & notice there's no airbox.

Have a look in the boot & that sticker says her engine code is 'AZD' if that makes a difference? Surely not though as it should have one?
But when i google "Golf AZD engine", the images on google look the same - no air box.
Yet when pricing up genuine VW parts & i gave VW her registration, they came back with a price for an air filter, so surely it should have one?
