Strange Lights and Noises in my A4 TDI

Hi, Just got a new A4 Avant 170TDI and I have noticed 3 minor things and would like to hear from anyone else

1. At motorway speeds the Aircon is very noisey through the vents and seems to be speed related!! The only way to quieten it down is to switch off Auto A/C or switch on Recirculation which would indicate that the vents are being turbo charged from outside at motorway speeds!! ???

and 2. a couple of unusual stalls on first starts on cold days and today the glowplug light stayed on with the engine running just flashing on and off...then later on restarting ...light stayed off???:confused:

and 3.. Can you overide the locking settings so that when I unlock the car with the remote ..All the doors open and the wife and children are not left in the rain while I try a number of double presses on the remote....

Otherwise great car..in red to buck the silver trend....but did everyone switch to red this year!!!

Cheers

Mark
