Hi all
Not sure if some one can send me to somewhere to find out what the
Model Numbers for a part number are.

Like a VW part number 025 109 612A. The 025 is Vanagon Exhaust Valve.
Now if it is a 043 109 612A What VW is This Exhaust Valve for?
Now if it is a 1H0 109 612A What VW is This Exhaust Valve for?

Is there a Prefix showing ALL Prefixes?
I've not been able to find one.
I have parts with 022,025,026,027 and a ton of others.
Any help would be great. Or just a link to all.

Thanks. You can email me direct if you don't want to post this to the list.
Thanks
