Day-time running light

Hello everyone, I’ve tried the search function, but I didn’t find what I’m looking for. The following is what I plan to do: I connected the day running light (TFL) to the fog lights (NL) in my Passat 3BG in the light switch. These lights now glow as TFL. Now please no discussions if this is allowed or not. I can also use the passing light. But in the Passat it works. Now I wanted to do this in the TTR: Light switch taken out, goes quite simply, T FL is plugged in and snapped to NL. Result: it’s not possible Now my question: does this have to be unlocked at the TTR? For example with VAG-Com? Many greetings and already thanks for the answers, deauville
