Hello there, I was wondering if someone could help me by showing me how I can code the Turn Signals to be active while CH/LH lights are active.
Thanks a million in advance!

David: Hi again! What type of lamps are fitted to the turn-signal assemblies on this car? Also, which turn-signal (front, or rear, or both)? If the car has incandescent lamps, then I would caution against this tweak. As some have found to their cost, the lamp holder on MQB platform cars (like your mk7) has what engineers call a "50% Duty Cycle" rating. This means that the lamp base is electrically rated for the lamp to be switched-ON only 50% of the time (which is what happens when the turn-signal operates -it flashes ON/OFF). In effect, the lamp base relies on the OFF period in the turn-signal to cool-down for each ON/OFF flash! However, when the turn-signal lamp is used for another purpose (like CH/LH), this cool-off period doesn't happen. Again in engineer speak, the turn-signal is forced to operate in 100% Duty Cycle mode. Alas, the result is that the lamp base over-heats and it can char and eventually fail!! Of course in CH/LH mode, the amount of overheating depends on the period of operation of the lighting function.
So, with my caution above as context, if you still want to proceed, - you need to add the following Leuchte-commands to the appropriate Leuchte-sets:
For the front turn-signal lamps - Leuchte 0 BLK VL B36 and Leuchte1BLK VRB20
- Lichtfunktion G > Coming Home oder Leaving Home aktiv
- Dimmwert GH >127 (see note below)
Note: change 127 to 100 if incandescent lamp
