Talking 2017 E300- Just notice turn light makes no clicking noise & Blind spot does not beep!

Today my car no longer makes a clicking noise when I put on the turning signal but works!?

and blind spot works, but no longer makes a beeping sound when someone is in my blind spot!?

They must be related?

NO other problems, thanks in advance!

There is a small speaker on the driver side footwell area, that speaker is responsible for system alerts, "Don't forget your key" chime, seatbelt (maybe?), turn signal, blind spot, Anti collision warning, etc. check the fuse to it and check if that speaker isn't blown.

I've never had a blind spot warning beep, only the visual warning. Perhaps there is a setting that controls warning alerts.

Sorry I don't remember which fuse but check the speaker first, there might still be a fuse diagram somewhere in the trunk fuse box area.

That is strange, maybe it was an option to turn the sound on but if your indicators are not clicking as well, then it is that speaker issue.

Sounds good, means your speaker is working properly and you just have audible warning disabled as you mentioned.

I don't have a W213 around me so I can't go and look for you. There is a specific name for this speaker so searching online might not find it but you might be able to see it if you look for it.

There is a good chance that a malfunctioning speaker will throw a DTC. Scan your car.

Good for you of finding it to illustrate unless that is an image you took yourself, I have no chance finding such image online as I remember MB calls it some other name.

That said, OP's turn signal also doesn't click so it is certainly this being the culprit, it wouldn't be a disabled setting.

Sometimes after Instrument Cluster retrofit the wires for this speaker are broken, but mostly on 205FL

OBD won't tell you if you have a non-emissions problem. You need to scan with a Mercedes-specific scanner. XENTRY would be ideal.

I looked all over no speaker! OBD, hood latch, light, but no speaker, on the older ones that's where it was I remember. I took panel off.

anymore clues?? :-(
