The new S3 and the new TT are equipped with Daytime Running Lights rather than the extra halogen spotlight in the second unit in the headlights. These consist of a 21w normal longlife bulb and the can be programmed to be on whenever the engine is running, thus providing Daytime Running Lights. These DRLs are now recommended in most countries in Europe as research has shown that they do reduce accidents where people do not see a car. Of the countries I visit with my car they are still only recommended in France and Germany but are required by law in Austria. I understand they will be required by law in all EU countries by 2010 at the latest. It means you can drive with the DRLs on without having to have dipped headlights or any rear lights on during daytime.
Whilst I was with the salesman ordering my car he telephone a contact in Audi Technical who confirmed than my new Sportback would be fitted with the DRL system.
Having had a look at a new A3 that had just been delivered to my dealers this afternoon, I can confirm that they are now coming through with a 21w normal bulb in the inside position on the headlights to provide Daytime Running Lights.
