Chart of relays
Is there a chart of the relays in the W212 somewhere? I'm thinking I had a stuck relay related to my Airmatic system. I swapped it with another one in the trunk, and the issue with the Airmatic system went away, but I'm curious what I just swapped it with. The fuse chart shows the locations of the relays, but they're not identified.

Thanks, is there any additional information on what A, B, and G control? I haven't heard the term 'terminal relay' or 'circuit relay' before.

Edit: I guess they might be related to position 1 or 2: http://www.bosch-automotive-traditio...eichnungen.pdf
