The vehicle will not start. Not with the "key" or the button starter. Audi service claims its the battery but when the roadside service shows up its not the battery, so now a tow truck has to be called. This can happen at anytime and any place. Audi denies it is a computer issue but yet the vehicle completely shuts down and nothing is available - electronically or more importantly manually. Don't be out late at night or you might be a victim to more than a broken down vehicle. By the way this vehicle is less than one month old.

Lost all coolant due to radiator leak from road hazard damage caused by bad design of front lower grill. It has no protective mesh and clear openings for rocks to protrude. I found this on Audi forum two people now on the vairious boards have thought they lost their water pump, but in fact have had holes punched in their intercooling radiators by errant road debris which strikes the radiator at highway speeds and perforates it. Since the engine and supercharger cooling systems share the same overflow container, but are seperate loops, it's only a matter of time before both systems have lost all coolant liquid, due to the one way valve system, the heating and cooling of the coolant and the shared overflow tank. This is not covered by Audi warranty, and is considered wear and tear. It also removes the car from service until it parts are obtained and it can be repaired, not to mention the cost and frustration. forums.audiworld.com/showthread.php?T=2784308&highlight=nws4guy+mesh&page=22.
