    Horn won't stop honking!

    Got the car from the dealership yesterday, drove it home just fine. This morning, I get up, go to where I need to go, and when I come back and start the car, it is honking non-stop!

    I tried unplugging the battery, restarting the car, checking everything, nothing! Finally ended up taking the damn horn fuse out to drive home. Have to take it back to the dealership monday...hopefully they'll cover it even though I just ran outta warranty. It wasn't a problem until I took it into the dealer so they should still cover it.

    Any ideas? I think it have been something to do with the trim on the steering wheel they replaced. I think a bad ground or something, maybe the horn relay?

    for reference, car is '07 335i vert with 22.7k miles.

    Def it's because of the steering wheel. When they change steering wheel always something goes wrong, dealer changed the steering wheel and when i started to the car to come home BAAM, airbag went off.

    O_o wow. I've heard of this happening in some 5 series as well, some trim was changed and the dealer did something to relays and/or grounds.

    Yeah, but it happened too fast so i didn't have time to be scared. I wanted to listen a tilick tilick noise which apparently was idle valve noise, so my head was a bit close to the wheel when airbag went off; some say i was really lucky that my neck didn't brake, they told me some scary stories about airbag.

    Here is the steering wheel after the airbag was taken off - anything unusual?

    p.s. the green and black hanging off are the airbag connectors.

    The negative seemed like it was properly grounded...unless I am missing something, most likely the horn relay?

    You took it off yourself? Why not have the dealer handle this?

    Eh, really didn't feel like going to the dealer for a loose ground, plus it takes 10 seconds to pop it off with a flat-head. Taking it in tomorrow since it wasn't the ground.

    Sorry didn't update this, extremely busy week. Got the car back from the dealer, it was a wire stuck under the steering trim. They reinstalled the trim and it was good to go.
