My 2020 mk7 jetta doesn't even have those reflectors. But there's a rectangle hole on the bottom where that release bolt is for the door panel. Will these fit on the bottom in that hole?
Not sure on that, sorry. Do you have lights already in bottom of doors? If so it is super easy to swap them out. If not, search VW forums like vwvortex for articles. I'm sure it's been done.
Rosstech cable for VCDS or probably can do it with OBDEleven also but I am not sure. I have a rosstech cable using the vcds software. It is a must have for Audi/VW owners
