Funny horn sound...

Hello partners! I'd like to ask if the Mickey Mouse car like horn sound is normal in the F3X. Last night I used mine (with a careless biker) and I laughed myself of my BMW's horn sound I have a 2015 F32 435i. After a few tries, the horn stopped working. Some hours later I tried it and worked again (maybe some kind of protection measure of the system, I don't know)... I don't use the horn, so I don't know if that is the right sound

If that sound is not normal, I'll make the dealer to check it in the next service, I think it's not urgent. The car is still under warranty.

I will make a video this afternoon. It sounds like the Stebel Magnum (the second in this video):



Thank you and excellent day...

The clown horn sound is probably due to one of your two horns not working. Here's a link to a service bulletin:

Hi! The same as...? The horn sound has changed? I'm really thinking about it. I don't want the front bumper disassembled or scratches all over the place... You know, dealers are not always as careful as we can expect...

Yeah, it has a two tone sound, one tone died and it sounded really stupid. I have no idea what they did. But nothing visibly wrong.

Wow! I didn't know this. I wondered why the horn was so puny. My late '05 Altima had a much more commanding horn sound.

My F36 sounds like a diesel locomotive giving a warning at a crossing.

Ditto for me with my last car - 2013 335.

Brand new lease, horn worked for a while, then intermittent - sometimes wimpy, sometimes normal. Eventually was always wimpy. Dealer here sucks so didn't bother having the problem addressed.

It just died on me - making high-pitched squawking. Thank you for the TSB!

This is a result of moisture getting into the low frequency horn.

Happened to me as well and after the fix, it's been fine.

i couldnt find a service bulletin for a 2017 440i, so my dealer won't replace it, though it sounds to be very common.

Are you under warranty? Is the horn broken? If that's the case you're entitled to replacement. Warranty covers defects in parts and workmanship. Defective is defective, whether or not a bulletin has been issued.

I was not under warranty, but I bought the car like that. So I gave the sales dept hell and they replaced both horns as a courtesy (since they sold it to me claiming everything was fully expected and functional).
