Filtering referenced nodes where logged in user is a member
Ok Organic Groups. I got a long way with the following recipe. Unfortunately I could not set up an identical environment to yours. 

1 Add a Contextual filter on "OG membership: Group ID".

2 When the filter is not available Provide default value "The OG groups of the logged in user ". Leave the concatenator as "+".

3 Under More check "Allow multiple values"
