I'm amazed you lasted this long before needing to lube those seals. I had to do that within a matter of months of getting the car. Same with the previous.
So am I Joe, longer than I expected, the seals in the mk6 needed doing after 16 months so I got away with an extra 4 months with the R, lol. I think it's because (and this can actually work against you too) I often wax around the inside of the door (not the seals), which stops the waterfall of rain off the roof but also seems to keep seal creaking at bay for longer, but people have had this actually cause creaking.
