Domestic Duty limit and EU Rules

An interesting senario …

Driver is under EU regs from the start of the shift but has to drop the truck off at the dealers for service/repair near the end of the shift

The dealer lends the driver a van of 3.5 tonnes MAM so he can go to base which is abut 30 mins away

When the driver drops off the truck he has so far completed a shift of 9 hours driving and 3 hours other work making a total of 12 hours working time with a total shift timme of 13.5 hours so far

If he has a 9+ driving day under EU regs he can drive a LGV back to the yard because he will have both driving and work time left to use

Does the van come under domestic regs?
If yes, can he drive the van back to the yard?

If yes for domestic regs which would also be a yes for the driving time then what about the duty/work time ? - are we saying that he cannot do any domestic work because he has already done 12 hours work time ?

I can see why VOSA are tending to ignore this issue because it does not make sense
