picked my new toy up on sunday, everything was perfect.
Monday had it parked up at work at the end of the day it started perfectly (i didn't put my foot down, was allowing it to warm up.)
as i got on the motorway i went to put my foot down and the turbo sounded like it was struggling to make boost, this continued, pulled over turned the car off and back on, started boosting perfect.
Same thing happened again this morning!
Im new to an S3 maybe it doesn't like the cold?
