Heated rear window ON when off?

[Bingo887]

Hi there

I have a 2014 Berlingo Hdi 1.6 Diesel Multispace.
When I drove it recently on a frosty morning, I noticed that the heated rear window was on and melting ice, even though I had not turned it on and the switch was off.

Does anyone know what might be going on?
Does the Berlingo turn on the heated rear window to create extra heat as part of DFP regens?

Thanks!

See the first post of this thread: https://www.berlingoforum.com/thread-21909.html  In particular note the line, "Next time your ECU decides it needs to regen, it will turn all non-essential electrical loads on".  So yes, it looks likely it was doing a regen.
