Auto door locking

[CarbonGTD]

I have the door locks set to lock at (around 10mph?) when pulling away (I have a 2020 Mk 7.5 GTI PP).  This has worked faultlessly until recently - now it is working as it should around 80% of the time - the rest of the time the locks sound in the usual way but the red glow lamp for the door locks (on driver's door) doesn't illuminate, and as I'm driving along the locks are 'activating' themselves on and off at random.  Has anyone else had this happen?  Does it sound like a possible water ingress issue impacting he electrics do you think?

Had it on my drivers side not locking sometimes and it needed a new Solenoid. Because it wasn't locking the Module in the rear N/S passenger door would randomly click and the lamp also did not illuminate.

Great, thanks for your reply Finglonga - sounds very similar - I will get it booked in to be looked at (as still under warranty)
