Static on phone calls - 2021 M3 LRAWD

[Soul Surfer]

Hi all,
I have already set up a service call for this, but I thought I would reach out to the community for some insights and experiences.

Here's the spec:

• 2021 Model 3 LR dual motor, probably June build as is was a showroom car
  • Software 2022.12.3.2
• iPhone 12 Pro running iOS 15.4.1

Whenever I am on a call using the infotainment bluetooth, my caller always complains of heavy static. If I switch to the phone's speaker, it becomes crystal clear on their end. From my end, I hear absolutely no static whatsoever. Has anyone had this? Could you share your findings? Thank you.

Not sure if you have tried it - but Bluetooth on my BMW had a similar issue in the past- removing the bluetooth device on both the vehicle and phone, rebooting, then re-adding fixed it. If this doesn't work could be an issue on the hardware side.

I think you’re referring to unpairing the device? I will definitely try that. Thank you.

Unpair but also delete the device if it remains - on BMW's it still remains on the infotainment even when unpaired on the phone. You have to delete it in there. I am just assuming it is something similar on the Tesla.

I think so. It just means that I need to setup the phone key again. No prob. Just annoying

I know this has popped up before, but I’m blanking on the solution.

I might suggest using the scroll wheels to adjust the volume during a call, and see if that helps any.

Thanks for that advice. It seemed to do the trick. In fact I cancelled my mobile service appointment.

1. I deleted the phone from BT as a phone device
2. I deleted the phone as a phone card
3. I re-paired the phone to BT
4. I forgot to add the phone as a phone card and only realized this when I got back to the apartment (first world problems)
5. Went back to the underground garage and added the phone as a phone card.

I had checked it calling my partner and she said it was now clear.

Great! Glad it worked - the write up will surely be appreciated on the forums for future issues.

I’ll try to remember that solution.
