Hi if your talking about the green menu I would steer well clear of it unless you are totally at home with the adjustments to be done as if you get it wrong you can FRY the MMI and oh boy is that an expensive hobby.
Hi they all do it not just Audis, when I was running Mondeos that was there favourite trick as well as spreading foam crumbs all over the carpet I used to go down the breakers and find a car that was picked clean and buy the passenger seat foam and use that as it had less wear, I think the new foam is probably your best bet and is easily fitted so that will be it for another 168k by which time I think you will be past caring LOL.
