It was the transmission selector switch on the side of the transmission, losing contact inside, confirmed by pulling the switch, actuating it manually, and checking for continuity at the pins. Opening the switch, cleaning and bending the spring contacts for a better connection, and resealing the switch resolved it in my case.

ok thanks for heads up on this re power steering fluid on alternator...volts are 13.9v car started and as read via no.9 in obc...
Just hoping gonna find a mechanic at short notice that doesnt have 2 week waiting list...plus other than the visual inspection for leaks the fluid level can be topped up at least....will scanning tools point to the transmission selector switch if it has a fault?
