Long time, no see...

2016 S5 here, with keyless entry.

The last week, my keyless entry will unlock the doors, but neither door will lock by touching the sensor on the door. I can lock fine with the key fob though. Both keys are identical. VCDS shows nothing which looks related (there are a couple of unrelated codes, but nothing to do with electrics).

The only other "oddity" is over the last few days whilst it has been cold, the alarm LED has stopped flashing after a couple of days and the doors have not closed properly - like the lock in the door is stopping the engagement with the body catch. This has only happened when the car has been cold and left for a few days (don't drive it Fri-Mon).

Possibly battery related (but car starts fine when I use it - no hesitancy or anything else)?

Anyone with any ideas?

Thanks
