Good afternoon everyone. Looking for some advice on my 2019 BMW X3 2.0D.

The other day when pulling out of my driveway I noticed a strong smell ⁃ burning rubber or electrical fire type of smell and a couple seconds later I recieved a Power Supply warning message on the console:

stop carefully. Do not continue driving. Failure of safety relevant features.." (See picture)

Note: the check engine light had come in recently which I had taken to a garage and they replaced the transmission fan (l believe). They told me they saw some errors about the NOx sensor but it was not permanent so they told me to drive after they cleared it and see if it came back on ⁃ well it did. All that to say the engine light was on before this happened so T cannot say if this new issue triggered an engine light on of itself.

The smell on its own was quite alarming so I pulled back into the driveway straight away.

I was able to pull diagnostic codes such as permanent error codes (none), info memory codes, and error memory codes apologies for the wording, I am a novice when it comes to auto repair) ⁃ see pictures for reports..

Doing some basics troubleshooting I realized the serpentine pelt seems to stick/slow down/stop after about 45 seconds from starting the engine. I was able to take a video to share

s it something Ican fix on my own? Do you believe it could be a serious issue? Is the car safe to drive to a close garage or should I have it towed?

Any advice/guidance is very much welcome and appreciated.
