Poor idle. Runs well when warm. S.A.D opens and closes

Hi all. Need some advice on part number for AFM. I have a 1989 1.6 GTI. 

She idles very poorly when cold

 She hunts until warm but then runs well when warmed up. I heve checked the S.A.D and it opens/closes as expected.  It also has power source. All hoses are good,no sign of air leak. The Bosch air flow meter on my car is 

028 0202109. I am starting to think that this may be incorrect part. Can anyone confirm this for me? 

Or is the a way of adjusting said AFM to help poor idle? Any advice would be appreciated. 

Thank you.

Stephen

you want an 056 for a 1.6, you have a 1.9 afm there.

That's that confirmed so. Thanks welshpug. Appreciate the knowledge. Just ordered used correct 1 from Spoox. Couldn't get new 1 from Factors here.

Thanks again.
