Audi A4 cornering foglights

Hello,

Has anybody activated the VCDS option for cornering lights for an Audi A4?

I believe this activates on of the foglights when a turn signal is activated at night.

Has anybody had an success with the system?

Thanks

I've set it but i can't say it seemed to make much difference, the fog bulbs don't seem to be at full brightness but not been out in the dark to check it again since.
