Horn Replacement
I searched but could not find one. There is a youtube video on this but it requires me to remove the front bumper. Does anyone know of a DIY horn replacement without removing the front bumper?
Can I access the horns thru the LED DRL grill or is there a way to remove the lower grill to access the horns located inside the bumper.
Thank you.

I did both of mine without removing the bumper. This is on a pre-facelift vehicle, but I doubt it's much different. The passenger side one is easy through the fog light/led strip opening. The driver one is an absolute nightmare to get to though. I ended up removing the front wheel/ fender liner and moving the washer fluid reservoir out of the way to get to it. It's doable, but not fun.

I removed my DRL's and found that I can access both horns. I want to replace them with Bosch Super Tones but they are too big for the right side. I will most likely relocate the horns behind the grill.

I did this on w204 ; 2008(pre-faceift; sport/AMG package).
Everything can be done through holes on bumper.
Remove plastic around foglights(3 x torx), and you can see/reach horns on both sides. Its a little bit tricky how to reach the screw and small hands are advantage.....but it is possible. On R side you can access also from motor(from above) side.
Remove horns together with carrier/holder & remember which is L and which is R & orientation of horns. Replace horn(s) with new one.
USE ORIGINAL HOLDERS and Horn must be in the same orientation as original one !
I replace horns with BOSCH EC-9 EVO (set of 2-different tones:420+510Hz) = 47€)-which are the same as original, just orientation of plastic shell/"snail"(& consequently position of conections) is different,but this is not big deal as wires are long enough(U will know what Iam talking about when you will replace first one...
)
Good luck.
