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.

DO you know which fuse and fuse box, there are 4 fuse box's on my 2017 e300 w213

and what is key chime?

thanks!!! :-)

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.

Massimo Here

It must be the speaker, checked all the fuses in all 4 locations!

also my door chime and left key in car chime is gone also!

so you have a pic of where that speaker is? :-)

ua549

Turn indicators click.

Massimo Here

no, I think its the speaker, you have a pic of where and what it looks like? :-)

W205C43PFL

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.

No OBD codes!

Another model from another side, but you can extrapolate

...

Massimo Here

oh yes! thank you!!

Has to be speaker all fuses are good!! checked them all! :-)

Massimo Here

audible warning disabled? where would I turn that back on? thanks :-)

W205C43PFL

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

Massimo Here

thanks, but I already tuned that on!

Massimo Here

thanks but never messed with that!

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.

What is that from?

Massimo Here

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?? :-(

here's a photo I took....
