Is my car running Windows ?

Driving along happily - no problems - then : BAM ! Instant Limp Mode. Car just died.
- Tranny indicator on the instrument cluster is inverted
- Oil Low warning light flashes
- Check Engine Light Flashes
- Battery Low warning
Accelerator disabled. No power. Had to pull-over.
Ignition off, back on again, drive away, no problems.
Of course Oil & Battery are perfect.
So I did a dump via VAG-COM. No special ECU faults. But the TCU has a fault indicating it lost data connection to ECU.
I'm used to this kind of crap from Microsoft - not from Bosch. Did someone install a Browser update without my permission ?

Sounds like the ECU lost power somehow but the TCU did not. I'd VAG the other control units (ABS, cluster, etc) for clues and break out the Bentley wiring diagram.

I would try unplugging the instrument cluster and plugging it back in first as a no brainer, no troubleshooting required go/no go
