Nightmare on horn failure and MOT failure

[djm17]

Those who saw the earlier post about my clk horn and steering wheel might be interested to know that MB have still not sorted the problem. They say they have checked;
all the feeds and fuses
relays
earths
contacts for corrosion
ignition circuit
ESC circuit
Instrument circuit
They have replaced the;
airbag
spiral contact disc (outer and inner)
horns
They are now going to check all the codes and the wiring and ring me on Monday.

Any ideas?
