On starting my 2018 SQ5 lots of warning lights stay on and the system runs through various electrical function warnings.
On driving off certain functions are unavailable and a variety of lights remain on.
It sounds like a serious fault but before I head to the dealer is there anything I can try, such as disconnect/reconnecting the battery ?

Check the battery voltage. Modern electronics hate low battery's

New battery is the usual answer.

What voltage are you getting before starting and while runing?

That's a bit low. Try giving it a good overnight charge, see if is any better.
2018 battery should still be good without knowing how many miles it's done.
If you're doing lots of short journey's this time of year with seats on and climate running it will soon drag the battery down.

Thanks for the advice.

Charged all night but has made no difference so I think a garage visit is now required.
