Dig out your Haynes manual, it has procedures for tsting the 1.8's EFI bits. There is a resistance test for the AFM. You can also push the flap in it open by hand and see if it sticks anywhere; if so then is needs to be replaced.

The AFM hangs off the side of the air cleaner. It's got a quarter-circle "bump out" on the side, and an electrical connector.
