Coupling Allocation
WARNING: This page is about a different car, the 2018 Volkswagen Jetta, 2017 Volkswagen Jetta, 2016 Volkswagen Jetta, and 2015 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The connectors for fuel, vacuum and ventilation lines are marked with colors. There is either a colored dot on the connector or the release button is the corresponding color.
The connector couplings must >>audibly<< engage when locking.
Pull on the connector coupling to make sure it is secure.
