Incorrect range and charging - Can't find any solution online

[TajSingh]

Please help. My 75D is showing incorrect range/charging information on 3 screens since morning:
1) 'Behind the wheel' dashboard shows 116 miles and is stuck there since morning (I've commuted 20 miles) (image attached)
2) Touchsceen dash show nothing and just dashes. (image attached)
3) Mobile app screen shows 87 miles (image attached)

I also got alerts for low battery when I drove this morning and returned this evening.

Car is charging now but don't know which range to trust (perhaps the mobile app)

What's going on? I can't find any answers online. Pl help.

Have you rebooted your MCU and instrument cluster? Start there. Hold down both scroll wheels until center screen goes black, then hold down the two buttons above the scroll wheels until the instrument cluster does the same.

I agree with @ucmndd . When in doubt please reboot your 2 computers first (central display and instrument display).j

And in the meantime, trust the Tesla App, or Teslafi....

Rebooted the two computers and everything is working fine!
Thanks a lot @ucmndd @aerodyne and @Tam!

I didn't know about holding down the two buttons above the scroll wheel. When I hold the scroll wheel buttons it reboots both displays.

I asked an SC tech if I also need to depress the brake when holding the scroll wheel buttons but they said nope, brake or no brake does the same thing

Heresy!!

Should have noted that doing them separately is a “MCU1 only” thing. Cars with MCU2 (so post March 2018) behave as you describe.

I have an mcu1 and just holding down the scroll wheels reboots everything. Never even heard about the buttons above the scroll wheel.

Right. Just pressing scroll-wheels did the job. Didn't have to do press the buttons above the scroll-wheels. I have a 2018Dec modelS.

It's not like reset isn't the first thing everyone does with their cell phones. That's what a Tesla is after all, a cell phone with wheels.
