Long Beep noise 99/C280
 

Hi All,

1. I’m trying to locate a long beep noise from passenger side, it comes on at random with the environmental unit on or off. It’s not the parking break being left on because it’s not a beeping, just a long high pitch beeeeeeep that come on and off at random.

2. There is a part that it could be coming from but not sure, it’s located on the upper right corner of the passenger foot well see pictures attached. And what is this part anyways.

Thanks in advance,

It looks like a hands free speaker for cell/car phone. Do you have a mobile phone?

Not original? I’m guessing?
 

1. So my guess is everyone with or knows this car year/model 1999/C280 US specs that this is an add-on not original or an option?

2. It’s my cousin's car he did say it has a phone in it, will try to find out more, him and the car is across town…and oh he is not the original owner
