a. luck of oil VW 503 01
b. Windnoise from the sunroof
C. Service in 1500km

a. Finally the specific oil for the S3 VW 503 01 is availiable here in Greece and costs about 20$ per litre.

b. Audi's final decision is to check the computer that controls the roof and trim it accordingly because the roofs mechanism has a margin in the movement of about 1.5mm + or - controled by this computer. I wlll revert with the developments cause the car is now in the process of installing ICE. (Pioneer 99R Deck,Boston Accoustics 6" mid, RF Power 4" and tweeters, two 15" subs Rockford Fosgate DVC, 800 W Rockford Fosgate Power Amplifier, 12-disk cd-changer with vocal control, etc...)
c. As far as the premature first oil change(at 1500 klm) is concerned i ve been convinced that it is not needed.However, after discussing it with Audi's dealer I ve decided to reduce the period of the oil services from 15000klm to 10000klm to cover the demanding needs of a car used on Greek roads/climate!...
