So light came on and has stayed on for 2 days now. Car otherwise behaving normally and charges fine. The only issue I had was the auxiliary climate control has been inconsistently working when manually switching it on from the app (using timer seemed ok). Also, a week or two ago there was a "charge fault" message on the app screen, yet nothing was indicated on the car gauges until the recent CE light. I drive almost always in electric mode (original tank at 7/8).
I also have a Porsche Cayenne e-hybrid. One time I hooked it up to a public charger which seemed to be out of order. The Cayenne did not like that and threw a check engine light immediately. However it did go out on it's own after a couple days. Not sure if this is a similar situation. Coincidentally, I had also just used a (working) public charger prior to getting this check engine light.
Will take to the dealer soon to check out and will update here. Hopefully it is something simple and easily diagnosed.
