Wifi and bluetooth not working - stuck at 'initializing'

[Natuglen]

My 2015 90D is unable to connect to wifi or bluetooth. Is stuck in "initializing".

After driving for some time the MCU shows "Bluetooth Not Functioning Correctly. Needs service" I have made an appointment but its more than a month away. The only advice from Tesla so far was to reboot the MCU and delete the car from the phone....well, it doesnt even get to the point where it can show wifi or bluetooth devices.

Have tried rebooting cluster and MCU without improvement. Is my MCU going bad?

I had the same issue with my P85D recently. A scroll wheel reboot and repairing the phone solved the issue.

Likely emmc wearing out. Consolidated eMMC Thread (MCU repair) here's a post you can look at with more details. @LuckyLuke can help you with a mail repair.

Ah yes and so the prediction came true and the MCU did not boot this morning. To add to the frustration, the sunroof was open at the time. While not an issue while parked in the garage, I surely do not want to leave it like that at Tesla.

Any ideas how one can close the sunroof with the MCU dead the Tesla app thereby not working?

K, the emmc is dead for sure... You can try a reboot to see if mcu comes back one more time.. The chances to recover emmc for 3rd party drops though, however if you do get the mcu back up you can close the roof ASAP. You can also go to SC to get new MCU anytime, they can always restore you.
Also since you MCU failed completely now, you lost BT and WIFI because the driver file got corrupted, which will result in BT and WIFI never completing initialization.

You have a 2015? Keep an eye on your MCU/eMMC.

I do. I’m sure it’s due to go at some point.

Any other things to keep an eye out for?

Please look at the first post in my signature. We can help upgrade to a longer lasting eMMC. In case you dont see it, Consolidated eMMC Thread (MCU repair) will also direct you there.
