Bad Seating

Are you saying the seat goes back, but stops 3" short of where it used to? If that's the case, it might be that the seat module has lost it's memory (different from the 'memory' settings). Just a thought.

...have you asked this of your service department?

Yeah... that's just that it lost it's memory - that upgrade has nothing to do with the seat, but could reset your saved settings. Happened to me too.

Due to a faulty air con drain valve, the seats to come out very wet carpets. The control that modulates the seat setting for the back rest and base , now cuts off short.

On a 100mile round trip I was adjusting the seat every few minutes trying to get comfortable. Used to fit like a glove. The dealer has had one go. Going back in tomorrow.
