I purchased a new 2021 TT RS a month ago, and just now noticed that something is plugged into my OBD II port.
What is this box? It has 4 lights across the bottom, 1st light is lit and has symbol of car below it, 2nd light is lit but I can't decipher symbol below it, third light is flashing and has a signal strength bar symbol below it, and 4th light is unlit and has a bluetooth symbol below it.
Anyone know what this box is and why it is plugged into my OBD II port????
Thanks!
