Yes a common problem AND a common topic here on the forums... to quote myself:

If you want to read more about it there are a few threads about that here and a really good one over on Rentech.com Horn Problem, Horn problem

other threads here on 986forum:

Please HELP! Horn going off on its own

My Car Honks When I Brake!!!

Horn doesnt stop Honkin...

Didn't read the articles kabel is refering to but, a really down an dirty method to remedy the situation that will last forever is to simply blob 3M silicone form a gasket where the bushings used to be on both sides.

Lightly put the screws and the horn pad bracket back in. Shim it out the thickness of the original bushing (if you still have a decent one, about 2-3mm?). Let it cure over nite and presto. It will be stiffer but at least you won't be getting flipped off by the guy stopped in front of you any more. You might want to put some car wax on the back of the bracket so it dosn't stick to the frame if you want to take it apart

Mote: if its to stiff and you waxed the right surfaces, you can take it apart again and shave the thickness of the gasket stuff with a new utility knife blade,,. God I hope I didn't repeat Kabels links

You did, but whatever. I need to go back and do that again, guess I didn't put quite enough on the first time.

"My horn blows without my help" brings back a lot of memories. This was my first repair. Cost me $200 at the stealership. I didn't learn about the rig-fix until much later in Boxster ownership.

Now I have a 3 spoke and that doesn't happen to these wheels from what I hear (or don't hear).
