Climate Control Lights Flashing

[jason.oneill4]

Hi Folks,
This happened today in the Cali (2016 T6 54km on the clock/full service history/loved and cherished ) -> The lights on the climate control panel started flashing and the temp display read 88.8 (when van switched off).
It’s a warning of some kind presumably?
Any ideas what it’s for?

The van is with the AA for a replacement to an ABS sensor that failed. They were running diagnostics. They reset the computer and the issue (flashing lights) went. They said it was a
software thing…
Thank you.
