Creaking / squeaking window seals R56

[Alex from NM]

anyone had any problems with the above? I have a mystery squeak. Even had the whole rear panels stripped out and dynamated (see below) but still can't find it. I'm convinced now its coming from the rear window seals, which as far as I know are immovable :ragin:. Was going to try some Gummi Pflege in them to see if it would soften them up but just wondered if anyone else had had similar issues.
