Dear all,

I'am very new to the VAG Com world to which i need some advice. Situation:
I am planning on buying the new 2009 fibre optic rear lights from vagparts.com for my A3 to which they have advised me that i will need to re-program the car to let it know that i have the fibre optic lights fitted.
Question 1: which cable do i need to buy to fit to my car? (2007 Audi A3)
Question 2: can i re-program the car to let it know i'm running the fibre optic lights just using the shareware version of the software from Ross Tech or will i have to buy the fully licence copy?
Question 3: Does anyone know what the code number is to do this?

I am quite hesitant about doing this as i do not want to wreck my car by accidentally modifying something. Is there anyone in Stoke-On-Trent that has these facilities?

Regards,
