Hi All,

I have quite a specific question and I wonder if you can help. I am after understanding if Mercedes do a part for a back seal that's part of the Air Mass Flow Sensor unit (See the picture and line highlighted in red

). My car's seal has broken as the rubber came out and in process of the mechanic trying to fit it back in it broke.

My question is:
1. What is the name of this part if one exists?
2. Do Mercedes / or other vendor sell this? or do you have to replace the entire unit

I doubt if that is available separately from the dealer. You can buy the whole unit Fairly cheap on Ebay.
