Hello again,
1974 240d.
I'm trying to diagnose a run away engine - idle problem.
I tested the diaphragm and realized no vacuum was present so I removed the housing to check the diaphragm.
Upon doing so, I noticed two small tears in the diaphragm.
Has anyone else has ventured into doing this. I did a search and came up with the same issue, but no one addressed how to specifically remove the diaphragm.
My problem is I am currently unable to get the diaphragm out of it's current position. Does anyone know if I had to remove the housing where the diaphragm sits or does it just pull out of it's current seated position?.
I attached a photo of the diaphragm with the housing removed and where I am at. This is a photo I removed from another thread related to my problem. The photo is nice and clear.
So looking at the photo do I have to remove the screws to release the diaphragm or does it just pull out, any insight?
Looking at a copy of the manual dealing with this subject, see address below...

Reading bullets 2 and 3, it sort of indicates that you remove the first housing which I did and then remove the "larger housing."
Would that be the larger housing that is seen in the photo with the straight edge screws? I do not want to remove that larger/secondary housing and all of a sudden I have parts falling all over the place.
Thanks in advance,
Dwayne
