Great answer David25, I've got some LEDs in work and there is an option in VCDS to code the footlights to LED, I'll give it a whirl and report back 
No problem.
Do you have the actual Audi light units? I'd like to know if they fit directly onto the existing connector
OR do you need a convertor cable (repair cable) as documented in the R8 light conversion above?
Also, if it works but the light is RED, disconnect it quickly as it will overheat and reverse the connector.
