If I recall I used a small ratchet to turn the torx bits.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Temporarily pull the fuse.
If you brake with a hard downshift does the horn honk? If so g's are the cause. Either the switch is gone or there is a short.
I apologize for laughing at your misfortune.
Fairly common, but requires steering wheel air bag removal and replacement of plate behind steering wheel air bag. Search the forum for horn braking...many have experienced this before and did a write up on it.
no need to remove the steering wheel but you do need to remove the air bag unit in the center of the wheel to gain access to the Air Bag Retaining Frame behind it. My horn was doing the same thing and I replaced the retaining frame which solved the problem. The rubber bushings get old/soft and flex too easily causing the horn contacts to touch over a bump or when slowing down. It's a couple of Torx screws behind the steering wheel to have the air bag unit lift out. It's a little more involved than that but I did it in about an hour. No problems since.
The part number is 993 347 088 01 - at least for my '99 C2
I just did this fix a few weeks ago. Putting in the new (aluminum) horn frame is pretty easy but you do need an extra long torx bit that is the exact size. The torx screws in the back of the steering wheel that need to come out are deep. If I recall I used a small ratchet to turn the torx bits. The screws can be in there fairly tight. The new horn frame set me back $80. There are those that have successfully rebuilt the bushings on the horn frame so that is an alternative to buying a new one.
I took a 2 Pc of rubber hose and put it under the plate. It was meant to be a temp fix. But it's been working fine for 3 years now. So I have left it alone
