I looked again for the Klima and found 3 large [6 inches long] relays that include the 4matic and 2 others I could not read without removing[they are fixed in front of one another] Also the MAS to the left and the OVP to the right.

There is a small metallic relay behind the OVP that I could not see markings on.

I got the idea [after searching for the Klima yesterday] From another Benz forum that I do not have the Klima because I have the MAS[I don't know what that stands for]
