I have and have used it on my 09 S5 and a friends 09 A4. I have someone that wants me to use the VAG COM for his S6. I know the winking and basic features should be the same, but he said that During the day, the LED are on, but when the headlights come on, the LED's go out. Is this true? he wanted to have the LED's stay on when the head lights go on. I thought it would be like my S5 where they just aren't on full bright. Can someone confirm this and if so, give me instructions on the VAG COM for S6.
