eHybrid preheating issue

Bit of an obscure question, I know. But does anyone know exactly how the “preheat the interior” works on Cupra (or indeed, regular SEATs) eHybrid models please?

Specifically, what “triggers” the car to start preheating? Is is the local (car’s own) onboard timer? Or is it some signal sent to the car over 4G via some server over in Cupra HQ, which is linked to my “My Cupra” online account?

I’d expect the interior pre-heating to be switched on when the car’s own internal clock hits the set time (e.g. 07:30 or whatever), and there is no need for the car to talk to some remote server …

But despite my setting the timer very carefully in the Infotainment energy management menu, and despite the car being plugged in to a (working) domestic wall charger, there are some mornings, it just hasn’t triggered the interior preheating, so the car is cold inside when I get in to drive off (and more importantly, it hasn’t preheated the high voltage battery)

It seems pretty random. Most mornings it does work, but some mornings, it doesn’t activate. And I’ve no idea why. I know the car’s firmware (I’m on v.1969) is buggy as hell still, but all the same, it’s really annoying!

Which is why I was wondering if it’s controlled via some sort of remote server, rather than locally.

My previous car was a 7.5 VW Golf GTE, and that occasionally failed to pre-heat, but much less than the Leon does. I know that was a completely different system too (MIB2 vs MIB3).

Does anyone have any insight please?

I can “force” a preheat manually by using the smartphone app, and that works yeah. But it’s easy to forget to do it manually every morning; and besides, I shouldn‘t have to. The function to auto preheat via the car’s own timer is part of the functionality.

Buggy, buggy buggy … sigh … wish that new firmware (1984, is it?) would get released …

If I had to guess, I'd say it's activated by the electronics/software in the car. Because, this is a feature of the car and you don't need a MyCupra account for it to work.

Ahh, good point about being able to use preheating without needing a MyCupra account. I hadn’t thought of that.

Does sound like it’s just a case of the buggy Infotainment software then. Funnily enough it worked perfectly this morning. It’s just so random. Oh well.

Thanks for the reply.
