My Scania Stonebridge VDU also showed that my card had expired but with a date after :
DRIVER CARD EXPIRED 8/5
It was like that for weeks, I even got pulled by VOSA/(insert current name) and he said he had not seen that before. The card remained valid until midnight of the 7th, the next day I downloaded the old card and continued with my new one and the expired warning went away.
