Volkswagen ID.3 (2020) — Where is the OBD-II port?

Below the dashboard, driver area

Look into the driver footwell below the steering wheel. Locate diagnostic connection U31, item 8 in the diagram, to the left of the steering column above the footrest area. Check the cited manual and exact vehicle configuration.

Orientation sketch of the indicated area. Check the exact position and access in the source documentation.

How to find it

  1. Check the generation and year range above. Dashboard design and location can vary by market and version.
  2. Below the dashboard, driver area. Source landmarks: footrest.
  3. Use a torch to identify the socket. Do not dismantle the dashboard to search for it.
  4. Identify the trapezoidal 16-position socket. Switch the ignition off before connecting an adapter, then follow the scanner instructions.

Looking for a sensor?

Sensor positions depend on the engine code. For DPF, EGR, MAF or MAP components, use documentation for the exact engine. We do not infer location from model alone.

Manuals and documentation

Sensor orientation guides · MAF, MAP, EGR and DPF

General orientation only, NOT verified locations for a specific vehicle. Exact identification requires engine code, year and technical documentation.

MAF · Mass airflow sensor

Usually on the intake duct after the air filter and before the turbo or throttle, if fitted.

P0100P0101

MAP · Manifold pressure sensor

Usually on the intake manifold or charge-air pipe. A separate boost pressure sensor may also be fitted.

P0106P0299

EGR · Exhaust gas recirculation valve

Near the exhaust-to-intake recirculation path; some engines have EGR coolers and multiple circuits.

P0401P0402

DPF · DPF differential pressure sensor

Often in the engine bay or underbody, connected by two small pressure lines across the particulate filter. Exact placement depends on engine.

P2453P2002

Do not disconnect sensors, DPF lines or hot components to identify them. Codes are diagnostic examples, not proof of a fault.
