Just back from dealer (again), definitely no transport blocks in there. He showed me, looked right up to the bump stop and all around - nothing there!
It's obviously just me, but really can't feel any different in the DCC modes. He did say that 'sometimes' DCC can not work if the wheels are mis-aligned, but they wouldn't recommenced checking that until 2500 miles+ due to things settling down etc.
He also said that over time (car has only done 250 miles so far), I'll likely feel an important in the different modes as things start to settle down/soften etc. Everything is obviously brand new at the moment.
