I even tried putting drive mode in ECO and still all V8.
Sounds great! Actually mine never goes into 4 cylinder mode but as expected I have an M7 and never in ECO!

Cylinder deactivation working again. Saw it going to V4 when I took my foot off the throttle for a few seconds while in sport mode
It may have been working fine earlier today but I was not driving in a manner or there were a number of variables present that kept it from going into V4.

I'd be happy about it and drive on...

That would be my guess.
