Ok so the car is now seemingly had a more permanent fix. The squeaking noise is gone.
Apparently VW replaced the gaitors and top suspension strut bearings with replacement parts.
I will update with as many technical details I can after I get the report by mail from VW.
Another interesting thing was that they serviced the car as they had it in, with an oil change as per the instructions in the car's computer. It seems odd to me to do an oil change after only 8 000 km / 10 months, but I suspect it may have to do with my regular short distances driven, oil not heating up too often and therefore collecting water..?
