2001 C320 Intake Manifold/MAF issue

Hello,

2001 C320 132K Miles


While cleaning, MAF to address P0170/P0173 I noticed the plastic connector below the MAF housing was loose and could be wiggled easily. I am assuming that plastic piece connects to the metal intake manifold.

I suspect air/vacuum is being lost at that connection.

I am looking for a diagram of intake parts, specifically part numbers for the connector and any grommets between the MAF and the intake Manifold.
There’s not much room between the MAF and the firewall so I can’t see the connection. I suspect I’m have to remove the intake manifold to inspect further.

Will add pics in the AM with light!
