Same horn issue

Hi there I had this same issue just the other night, disconnected the battery and reconnected next day, and it was fine for about 4 hours then it started blasting again in a long continuous sound like someone was holding horn on. I checked my horn buttons and they were fine, has anyone replaced the whole horn button assembly behind airbag on steering wheel and did this help?

If not the horn buttons, then it is probably the hood sensor, check it and make sure it is adjusted high enough.

To all out there with this issue I went an had my hood sensor checked and it was fine, but the Rover mechanic said it was the Horn/Cruise control relay that was causing the issue, it was a $12.00 part that is in the engine fuse box a little square yellow box that just plugs in, he said he has seen a few of these on Disco 1 & II, the relay shorts out.

Hope this helps for those still searching for a fix.
