Fact is cars are nailed hard from day 1 and also when the dealership test drives the car before the handover. They do recommend 1500 kms before running the car at full regime, tbh it doesn't hurt to follow the recommendations, mostly to get used to your new car. My dealership confirmed that cars are run in way before you get to drive it for the first time.
How to keep the Revs down on an S tronic .... Drive select 'comfort' , kick down whenever you feel the need, all the snap crackle and pops but changes up at c 4500. Doubles the mpg too ;-/ works for now, roll on 1000.
