I think you've answered your own question...
Ok brains trust, just replaced the clock spring on my D4 due to some intermittent audio control and intermittent horn issues.
All seems good and it was an easy job, however the norm will not work at all now when operated from the steering wheel controls.
I’ve confirmed the 15Amp fuse in the engine bay is fine (tested), and the horn definitely still works (tried locking doors with bonnet up).
Only thing I can think is I did notice one of the connectors was a little loose in its socket. Small black connector with one black and one red wire. Possibly this is for the horn?
Don’t mind pulling the wheel off again tomorrow if this is likely the culprit.

Ok, dismantled again, cleaned all connectors and squirted with a good amount of contact cleaner.
Checked all electrical connectors for positive fit.
Everything works, bar the horn.
Ideas?

Check the connectors at the horns themselves?
Horn works because if you try to lock the disco with bonnet open it still gives the double beep.

I'll do this in the morning, on BBQ duty now.
Still, I would expect a new clock spring to work, my concern is the horn would not operate from the steering wheel consistently before the change over so it may not be a clock spring issue.
Not sure what else it would be though?

I think the horn that beeps when you try to lock an open car is not the same horn(s) that sound when you press the horn buttons on your steering wheel.
I think? the beep horn is inside the second battery box on the drivers side, I moved mine to fit a battery in there.
The HONK horns are likely to be in front of the radiator but I really have no idea on that one.
They definately sound different.
For what it's worth my horn buttons have stopped working intermitantly too, but I haven't done any work in that department.
Ok, thx again all. Found and fixed the issue, although I suspect it may reappear.
Issue was the horn relay, situated in the fuse panel in the engine bay. Didn’t click when horn pressed but fuse was ok. Swapped with the windscreen washer relay which was same type and bingo, horns work.
Placed the horn relay into the relay socket for the windscreen washer and washer also worked, weird. Suspect I have a failing relay and will source a spare in case.
Reassembled the clock spring and steering wheel (got this down pat now ), and tested everything. Will go for a drive later to confirm everything now works correctly.
