same issue on a 2021 auto cx. Has occurred 3 times now, no fault recorded. Each time I did a quick check to see no oil leaks and carried on. It took 2 weeks for the signal to return after the last occasion, I was in France.
Last occasion was on the way to Morgan for a service and they could not see a fault.
Sender has been replaced, cleaned etc and still occurs .
Learnt to ignore it with care.
How hard is it to fit a dipstick!
The oil pressure indication is independent of oil level indication which is just as well
