Does it need foglights with Led headlights?
It may not need them and I'm sure that some GTI owners may not use them, but they've been part of the 'face' of the Golf GTI since the mk2*, so seems strange if they've been dropped now. Some owners will use them in appropriate driving conditions (I would).
Like p3asa has said, it's quite possible that the early mk7.5 GTI's are the official dealer demos and, for whatever reason, they were built with no front fog lights. Time will tell when customer orders are delivered in the next few weeks.............l dare say that most forthcoming owners who have ordered a mk7.5 GTI and are awaiting delivery will expect their cars to have front fogs.
*some mark 2 GTI's had them so I'm assuming they were introduced during the mk2's life. The mk4's fog lights were integrated into the headlamp units so it wasn't obvious that it had them, but it still had them.
