A little story on my Highland journey today.
Short summary: Complete MCU failure mid-drive
Long Summary: I took my vehicle on a trip from Canberra to Newcastle, stopping once to supercharge on the way up. Brilliant highway car, although I am now more inclined to purchase EAP as I absolutely hate how AP dis-engages when you change lanes. Such a simple thing my old Golf could even do. I also had the joyous experience of an autopilot ban on the way up
(don't ask).
On the way back, I had to stop at Central Coast and Exeter to get the electrons I needed for the journey. It was pouring rain by the time I got to Exeter.. Not a worry, I headed into the servo, got a drink, fired up Netflix for a bit and charged away. When I finished, I stopped charging/unlocked the charge port and got back in and as I was about to pull out, the MCU (touchscreen) went black, a chime sounded and the 'PRND' lights illuminated. I did the 2 button scroll wheel reset, which after 30 secs brought up the 'T' logo, but it was stuck in a constant cycle, rebooting at least 5 times by itself, showing the 'T' logo and flickering a bit before the screen came back to normal. A little confused, thinking my car just had a bug it needed to get rid of with 5 reboots, I proceeded on my way. About 5 minutes later heading down the Hume in the 110km zone, the same thing happened again. Black screen, chime sounded, 'PRND' lights lit up. It cycled through another 5 reboots and finally came good again (total maybe 10 mins without a screen) after I was anxiously driving with no screen and autopilot still on. This happened at least another 4 times on my way home.
Things I noticed when your MCU has a meltdown:
Works:
Autopilot stays on, brakes as normal but doesn't provide auditory feedback.
You can wind the windows down
Doesnt Work:
Indicators don't illuminate or make a noise when pressed
Air con doesn't work/turns itself off
Windscreen wipers are manual only operation
And the most worrying point, you don't know what speed you're going.
I've gone into the service menu but it doesn't explicitly point out what triggered it. The only alerts that occurred during my drive/today are in the below pics. I've scheduled a visit to the service centre next week to hopefully work out what's going on.

Side note: when I crossed the border, it appeared to stop.. my car's clearly not a blues supporter.
