At 202k, I’d imagine it’s become a tad loose. I’ll hear cars go past, as if a window is open.
There’s a subtle whistle noise when on the motorway. It doesn’t take much force to push the glass up to hear the outside.
If you have slack in the linkage, the only thing you can do is replace it, there isn't any adjustment. You shouldn't be able to push it up when it is closed unless the screws attaching the glass to the mechanism are loose. Slide the covers off either side and check the screws.
