Merc update

[anshackles]

Few hundred miles done and nothing too untoward has surfaced.  Fixed the screen washer and the glovebox lid, fettled the driver's seat (which is rather worn) and made it a bit more comfy.  Removed the headlamp wipers (not working correctly) and disconnected the headlamp wash pump, which is I think the control unit sticking on.

still to do: change the oil and filter in the auto box and see if that makes it any smoother, it shifts a bit sharply at the moment.
