I suppose that is possible. The FSM (1985 "Introduction Into Service") doesn't discuss adjustments to the trimming plug, just prints the electrical diagram. I don't have a late edition FSM to check for detailed instructions. Later cars, like my 1987 300D have a similar trimming plug in the engine compartment and it does indeed change idle speed.
