The OBD port on the older Passat is located next to the handbrake, beneath a small rectangular cover. The Passat is a mid-size sedan designed by Volkswagen AG in Germany, classified as a B-segment vehicle in Volkswagen's lineup. Since its debut in 1973, the Volkswagen Passat has dominated the global automotive market for over 40 years with its high safety standards, classic design, and top-tier manufacturing quality, selling over 30 million units worldwide. Below are the specific details of the 2021 Passat: Exterior: The Passat primarily features adjustments to the bumper, adopting the same style as the Passat New Energy version. Interior: As a mid-cycle refresh, the 2021 Passat comes standard with a range of safety features, including front dual airbags, front side airbags, front and rear head airbags, EPB, auto hold, ESP, and more, ensuring vehicle safety. Powertrain: The Passat continues to offer three powertrain options: 1.4T and two variants of 2.0T (high and low power). The 1.4T version delivers 110kW (150Ps) and 250N·m of torque, paired with a 7-speed dry dual-clutch transmission. The 2.0T low-power version produces 137kW (186Ps) and 320N·m of torque, while the high-power version outputs 162kW (220Ps) and 350N·m of torque. Both 2.0T variants are matched with a 7-speed wet dual-clutch transmission.
My old Passat B5 has been running for almost twenty years, and I know the diagnostic port location like the back of my hand. Remember to lift that plastic cover under the steering wheel? It's right in the area facing your left knee, slightly above the accelerator pedal. You'll need to bend down and reach in to find it – usually a 16-pin black box tucked away in a tricky spot. Back when getting the car inspected, I'd always see mechanics plugging their scanners there. Later when I bought an OBD reader to check fault codes myself, I became quite familiar with inserting and removing it. For later B5 models, it might be hidden behind the ashtray or along the lower edge of the center console. That port collects dust easily since it's so deeply recessed, so remember to blow the pins clean before plugging in.
I had a hard time finding the diagnostic port on my 2002 Passat. I crouched in the driver's seat and felt around for a while before locating it on the left side of the steering column, tucked in the gap between the dashboard and the steering column. It's not very noticeable because of the metal bracket blocking it, and you need to turn off the ignition before feeling for it. The connector is a trapezoidal blue-black one, with nine pins on the top row and seven pins on the bottom row. During the last maintenance, I saw the mechanic plugging a tablet here to reset the service light. The interface has a hanging wire that just reaches the gear shift position. The electrical connectors on older cars tend to loosen, so it's best to wiggle the connector left and right before testing.
