Not seen this one mentioned but here is a tweak that when the main beam is activated (either by the flash or full main beam), the front LED fogs come on as well. I tried this out last night and it works really well. The main beam of the Xenon headlights gives a super strong and focused beam into the distance, and the front fogs very nicely illuminate the area to the front and sides of the car. When dipping for on coming traffic, the fogs just switch off in tandem with the main beam. When travelling at speed on unilluminated country roads, it really does light the whole road up for you.
Remember if you do this on a GTI or GTD, then as we have LED front fogs, don't forget to change the illumination value to 127 not 100 (which is for halogen fogs).Anyway here it is (credit to DV52 over at the vwwatercooled.com.au and vwvortex.com forums).
VCDS Tweak - Fog Light (and High Beam) "Flasher"
From the main screen select 09-Cent. Elect
When the BMC screen opens, select Security Access-16
Enter the magic number 31347
When the main BCM screen returns, select Adaptation-10
Change the settings in adaptation channels shown in the two Tables below to the "New Value":
Note1: The channels in the Tables below are about 80% down the list of channels on the VCDS adaptation screen
Note2: Select the adaptation channels carefully as other channels have similar descriptions
Note3: If LED Fog Lights are installed - change adaptation channel (10) on both left and right fog-lights to "127" (instead of "100")
Note4: Adaptation channels (11) - (i.e. last row in Table) should not need to be changed, but the settings should be checked
