I did the same. The last updates I had were.....Ford Power-Up 4.2.1 –
Background updatesFord Power-Up 23-PU2001-PR-FX – SYNC update to improve
large file handling I haven't had any further notification of updates
and my Sync is working OK.
Mine is still on 4.2.1, so I'm not having any problems and the problem
PU updates haven't yet been released for my car.I've switched off auto
updates, in case 4.2.2 or 4.2.4 are released for my MY so I can choose
when or if to upload to the car.
I had mine checked as charging fault alarm showed up, then disappeared
the following day, but I booked it in and they changed the Sync module
as well as doing a service.
