Horn changing tone

On my 2015 f10 550i, when its a nice hot day (NY) 90's my horn will change a note, and sounds like a 1915 model T ford. Then few hrs later or a drive on the highway, its back to normal. I will address this, on my next oil change visit, but does anyone having similar issue?

The horn on the F10 is actually a dual-horn with a hi/lo tone. It sounds like one of your horns may be failing. Not uncommon...I experienced the same and had the horn replaced.

Same thing happened on my '11 535i when I first took delivery. Both horns were replaced under warranty. It's a shame that these kinds of parts are made ao cheaply that they no longer perform their simple function. Have not had the issue with my '14.

I have also experienced this! I'll hit the horn to beep at someone and then a wimpy beep comes out, embarrassing lol. Doesn't happen too often though.

I was going to note the same. It sounds like one of the horns may be faulty. It happens. I experienced this on my Panamera shortly after I got it.

FYI, although the dealer replaced my horn without incident, I still find the fully functioning stock horn to be a bit weak. So, I went with the Stebel Nautilus electropneumatic horn which I've used on my motorcycles. It's small and compact, affordable, and easy enough to install, yet packs a bit more punch without overdoing it and sounding like it doesn't belong on the car. Best part is that I find the tone of this horn to sounds similar to that of other European cars, which suits the F10 much nicer than the stock horn.

The Stebel website includes an audio clip to hear it: http://www.stebel.it/stebel/products...CTROPNEUMATICS

You can also find plenty of example clips on YouTube if you search for Stebel Nautilus.

Happy modding!

I had this happen to me once a couple weeks ago - but a few days later noticed it was back to normal.

The best sounding stock horn I've had was the one in my old E36 - powerful and authoritative.

Munich really needs to address what looks to be a common failure and should know that as BMW drivers, the horn is a core part of the driving experience.
