What you bought is a VW part that dealers sell for $60 list! MANY people are selling that part for Mercedes.

A wholesale buyer can buy those parts for $40>

YES they will fit! NO they aren't for MB engines at all..

I have heard of MANY catalyst failures due to that part...

AS they say...let the BUYER beware!
