Do you use the gas pedal when starting?

The owners manual specifically says NOT to press the accelerator while starting the engine.
Picked my Winning Blue up yesterday, owners manual is still very fresh in my mind.

Not so in any EFI car - let alone a drive-by-wire throttle. The throttle controls the amount of AIR drawn by the engine and then the ECU works out how much fuel to put in depending on throttle position, load, etc.
When you are starting, the ECU obviously knows that - so I should think it ignores the throttle position totally for the first few revs. If it's like other cars it will also map differently when the engine is cold and won't let you give it full beans until it's warm anyway.
In some cars depressing the throttle whilst starting actually CUTS the injectors toallow you to crank and deal with a flooded engine.
Re the economy flame war - I had 290 out of the last tank and that INCLUDES touching 110mph once or twice. Hardly granny driving. The trick is not to change up too early, it's counterproductive.
I do miss the 75mpg I got out of the TDI on motorway journeys though.
Rough starting - mine was dicky for the first couple of hundred miles - it gets better as a) you run it in and b) the ECU learns.
BTW not only should you give the pump time to prime when in "on" position - you should also let the engine build some oil pressure before moving off by idling for 10 seconds or so. Specificially says so in the manual for the 8 but is true for all cars.
I open door, get in, turn key, count to 5, start, then close door, put seatbelt on, turn radio on, etc.

yes if you have flooded your 8 one of the steps in de-flooding is to hold the pedal to the floor while you crank for a few seconds. doing this cuts the fuel off allowing you to sweep the unburned fuel out of the rotors.

do this.. turn the car to accessory. You'll be able to hear the fuel pump clicking on. once the pump has pressurized, start the car. It should start right up.
