Help! Horn going off on R32

[ausgolfer]

Well driving to work this morning. I know pity me working today. 3 blocks from home. Going around a round about, horn starts going off solidly. After lots of embarrassment and trying to fix/fiddle I had to pull the grill and disconnect the horns(ouch contortionist hands!).
Any ideas on what the cause could be?

I dunno how close it might be, but I had similar with my alarm going off in my driveway when it wasn't being driven (broken). Traced it back to battery going flat. Happened about a month ago, battery died on me on saturday (autobarns actually had the right one for $140 fyi).

Maybe something like that or stuck horn relay?

Your alarm went off because it has a battery of its own. I've seen this happen before

The horn would have nothing to do with the flat battery. Its probably a relay
