Interesting for KB1 owners that may not know! New battery fitted , lost auto windows memory seats and so on, reset all that and stumbled across comments (google ) about resetting the ECU fly by wire , turn ignition on to position 2 , accelerator down to floor 30 secs ignition off but leaving key in . Apparently this erases all learnings that car and gearbox had about drive by style - maybe my imagination but the car is super responsive now and seems to shift better - no complaints before but DEF seems better !! Try it . For 30 seconds effort seems a good thing to do ! Any one else tried this ? Is it my imagination ? Thought I’d share .
