NZ-Merc

Hi,
My 2008 W204 the car horn is not very loud and out of all my various car it has the weakest sounding horn, has anyone else experienced this or repaired it.

Looks like possibly the front bumper has to be removed to access the horns, it would be good to know in advance which horn mainly fails so I can order one.
I have a 1980s BMW E30, I would be really happy if my Mercedes sounded like that.

Thanks in advance
Dave.

you are due for a new horn if all the contacts are not clean for correct voltage
