Any Ford Techs on Here?

Have issues with 2 Fords and local Ford dealers are booked 1.5month in advance an we don't have time to spend on them so if any Ford experianced people can say if any common issue?

First one is a 19 plate transit 2.0d. Headlights are ocscasionally flashing on and off even with van locked and keys far away causing battery to be flat on return to vehicle or in morning. No Fault codes anywhere, suspect BCM at fault?

Second 19 plate focus auto (newer style with turn dial rather than stick) driving along then jumps into neutral, coast to a stop switch of, goes into park and wont restart or wind over. Fault codes in most ecus all CAN related. Looking like TCM faulty?

Obviously can't diagnose without looking at them, scoping lines etc but does anybody works in Ford an has seen these symptoms before??
