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. :-(
