Thanks for your reply. How do I find out whether they had applied to
DVLA within the 14 days and that they were not supplied the information.
If I wrote to them, would they really tell me?

I think you want to write to them within 14 days anyway, and mention
that your vehicle was not there/ you were not driving/ you didnt' do a U
turn(whatever that is)/ U turns are not illegal/ they didn't issue the
notice within 28 days (although their website only refers to parking,
not moving traffic PCNs).
