Where is the OBD interface located in the Touran?

The OBD interface in the Touran is located behind the plastic cover panel under the steering wheel. Below are specific details about OBD: 1. OBD is the on-board diagnostic system in vehicles. This interface serves as the bridge connecting the computer to the vehicle's diagnostic system. Through specific programs, fault codes can be read from the PCM. Based on the fault code prompts, maintenance personnel can quickly and accurately determine the nature and location of the fault for timely repairs. 2. The location of the OBD interface varies among different vehicle models, and the exact position should be determined according to the vehicle's user manual. 3. The on-board diagnostic system continuously monitors the operating conditions of the engine and the working status of the exhaust after-treatment system. While driving, the vehicle produces exhaust, and the on-board diagnostic system will immediately alert the driver if it detects any condition that could lead to excessive emissions. 4. OBD simultaneously monitors multiple devices and components, including the engine, catalytic converter, particulate filter, oxygen sensor, emission control system, fuel system, EGR, etc.
As a Volkswagen Touran owner, I'm very familiar with this. The OBD port is usually located under the dashboard on the driver's side, near the base of the steering wheel. You can bend down and look at the lower left side of the steering wheel, just above the accelerator pedal, where you'll find that small rectangular port. It's designed there for easy connection of diagnostic equipment, such as reading fault codes or installing OBD devices. I often use it myself to monitor fuel consumption. It's safest to operate when parked—don't fiddle with it while driving to prevent accidents. Some older models might have slightly different positions, but most post-2010 models are the same. If you can't find it, the owner's manual is a great help—it will have specific diagrams for confirmation. Remember, this standard position can be found without any tools—simple and practical.
