General Irratating Horn Problem
Apart from going round roundabouts the other way.....
..... check the wiring in the wheel console, only 3 screws to drop it. You may have a short somewhere.

I hate getting the horn randomly when driving, it seriously fu*ks up my ability to steer the car. 
the horn wire inside the steering wheel must be getting pulled when the wheel is turned to the right. when you remove the airbag to inspect i suggest you disconnect the battery at least 15 mins prior to disconnecting the airbag, if you dont there is a tiny chance it will go off, especially when you reconnect it.
This seems to be a weakness on Mareas, mine has started sounding when it shouldnt. I took the fuse out when it happened and have run a wire to a spring loaded toggle switch gaffer taped inside the car for now. I had look inside the wheel boss, the wires are fine up to the connector where it vanishes inside the column. Reading the Haynes manual getting the wire out of the column and replacing it looks a bit major . Anyone here done this ?Im thinking I may tidy up the bodge and live with it as dropping the steering column looks like a pain.

just pull the wire further out the steering column so theres more slack, that should sort it. failing that you need to bend the brackets that the airbag attaches to so the airbag sits further away from the wheel.
Thanks Jug, however there is no problem inside the wheel centre boss, I took the 2 allen screws out and looked (scary around that airbag). The horn wires plug into a 3 pin connector and then it all vanishes inside the column, and thats where the problem is. I am sticking with the lash up for now and will come back to it when I have time.
After typing that I went out and took it all aprt again You are right Jug, the problem is in the horn push metalwork, although as I noted you cant just pull the wires through. Rather than bend the bracket out I put a couple of spacer washers in but it did not help. Im going to have another look later, last time I had to put the car back together after about 5 minutes but I have longer today.

No luck, just wasted an hour eventually pulled the earth lead off one half of the horn push and when you connect up the horn away it goes. It does seem to be further down the column. I got some weird results with the meter and this explains it.
This is scary , as it's earth lead off, will the radio and ECU ever work again, and fiddling around with the airbag clockspring. I'm not sure I want to bother actaully.

If anyone is interested this seemed to be the horn clockspring. I fixed it by putting a small microswitch on the steering column shroud to drive the horn relay. I fitted it so it's not a safety hazard in a crash and we shall see if its "secure and accesible" at MoT time.
