Angry No Turn Signal Sound on GLB250

My new 2024 GLB250 turn signals do not make an audible sound. A sound app on my iPhone detected a clear clicking when a signal is flashing but it is below the level of audibility. The dealer says that there is no separate flasher relay that can be replaced and no way to adjust the sound level. I don't believe an audible signal is required by law in Canada but this is the first vehicle in over 60 years of driving that has not had a clicking flasher. It is very annoying. Any suggestions?

Mine makes turning signal sound. It is coming from a small speaker below the steering wheel. May be that speaker is defective?

I've noticed the same thing with my 2024 GLB200d in Japan. My previous 2020 A200d turn signals made a clearly audible sound. But, this GLB doesn't. It's there, but only noticeable if I have absolute silence in the car - no road noise, no wind noise, no media. But, it's oh so quiet. I, too, wonder if it's legal.

Is yours also a 2024 facelift model with the MBUX2.0 NTG7 infotainment system? My previous Mercedes with MBUX1.0 NTG6 had clearly audible turn signals. My new one...not so much. :-(

I also have a GLB AMG35, and complained about the same issue (hardly audible sound from turn signals) to the dealer. They told me that I'm not the only one ... but there is no solution. Quite frankly, I find this unbelievable!!

Off topic a bit....years ago I was with one of my fathers friend in his Alpha Romeo and I noticed it had just one light for both blinkers....

I asked him about why there was only one, he said "Yeah, and it does not make that stupid click noise either, the car gives you credit for knowing what is going on" - somehow, that ride stuck with me for all these years (over a blinker!)

I often have my radio FAR to loud to even consider hearing a blinker indicator.

2024 GLC300. Turn signal sound barely noticeable. I'm a geezer and I did not want to be one of the old timers who drove for miles with the blinker on. Thanks to MB I guess I will be acting my age.....

Hi, on motorbike online shop, you can buy a buzzer easy to add with one cable on each turn lamp (right/left) and one on car ground with the possibility to adjust the sound. Perhaps it can be a solution....
