I've spent 1½ hours today struggling and swearing trying to get the larger rear seat to release in my 320 Touring. The smaller seat folds flat fine but the release mechanism on the large one has no effect.
With the smaller seat down I removed the metal saddle that covers a tube/bar that appears to connect the 2 seats near the base, and a plastic shroud that covers the tube, but this did not work. I then tried various other ways to get at the mechanism but with no success. I don't want to pay main dealer prices for what should be a straight forward job, but I'm running out of ideas!
Any advice would be much appreciated.
