My W210 was in the repair shop and the fuse/sam enclosure was disturbed now there is a multitude of faults concerning the control stalk i.e. intermittent wipers intermittant reversed right to left indicators headlight flash seems to turn of the whole stalk. I suspect the sam module wiring has been stressed and the board cracked. The vehicle is unusable and I do not know were to start to get it fixed. Can anyone help ?
