Haha, James Bond could make good use of the Audi's 'hidden extra's':
The 'Window Clip' Gadget - Bond uses his hand to manually force the door window down to escape from the baddies as his car is sandwiched by baddies and the door cannot be opened due to a low wall - he would have used the electric windows manually but this would have taken up precious time.
The 'Indicator Confusion' Gadget - Bond is trying the dodge the baddies in an urban setting with many traffic light's / junctions. He (being a good british citizen) accidently presses his indicator to let people know that he will be taking the next left - fortunately, the Audi has a hazard switch that bypasses his accidental attempt, he makes his turn and the baddies plough straight on.
The 'PCV mini oil-slick' Gadget - Again, this is a miniture version of the original oil-slick that the DB5 produced, only due to the environmentalists / Green Party, a limit has been placed on how much oil should be used to create a slick. Also - the slick is activated automatically - Bond has no control whatsoever when this will activate, he will only find out after he sees the car that was chasing him has now skidded, overturned and created a mahoosive fireball.
The 'Coilpack Flamer' Gadget - Again, whilst being chased, Bond's Audi is accelerating hard, he is 3 car lengths ahead when all power is lost, the EML light appears on the instruments display, Bond seems aggrevated by this, then all of a sudden, the unburnt fuel escapes from the exhaust, ignites spontaneously and the ball of fire kills the baddies (again).
Disclaimer - All the above 'gadgets' are available in all Audi's, no VCDS activation required. There may be more gadgets - these are the only ones I am aware of at present. Please feel free to add any gadgets I may have missed.
