We picked up our new GTI yesterday - red 5 dr, 18s, black leather, centre armrest, rear park sensors, winter pack - and loving it so far, great car

Asked dealer about running in, he just said don't go above 75% of max speed, and don't labour engine.
Has anyone had any more specific advice, such as don't go above x rpm for x miles, then y rpm up to y miles etc?
And with the car telling you when it wants its first service, which likely to be a year or so, does anyone change their oil earlier than that?What oils are people using?
cheers
