The horn contacts are corroded and the horn will not work consistently. It may take 5 or 6 times pushing the horn to get it to activate, or hold it down for a long time and try to move it around to scrape the corrosion off the contacts to get activation. It occurs whether driving or stationary. Many other owners have reported this problem on a Mini cooper forum. My vehicle only has 20,000 miles on it.
