While the driver-side lower dash area is the most common location, there can be slight variations. Sometimes, the port might be positioned slightly higher up, closer to the ignition switch, or even further down towards the pedals. In rarer cases, it may be behind a removable panel to the left of the steering wheel, closer to the door.

Variations Based on Trim Level

While the general location remains consistent, minor differences can exist between Passat trim levels (GL, GLS, GLX). These differences are usually related to the exact positioning or the presence of a cover. Consulting your owner’s manual is always recommended for the precise location in your specific Passat trim.
