Where is the OBD interface located in the Octavia?

The OBD interface in the Octavia is located in the fuse box under the steering wheel. Here is some information about OBD: 1. OBD stands for "On-Board Diagnostics." The more advanced OBD-II was developed in the mid-1990s. The Society of Automotive Engineers (SAE) established a set of standard specifications, requiring automotive manufacturers to provide a unified diagnostic mode according to the OBD-II standard. By the late 1990s, vehicles entering the North American market were equipped with OBD according to the new standard. 2. The key difference between OBD-II and previous on-board diagnostic systems is its strict focus on emissions. Its primary function is to monitor vehicle emissions by tracking the performance of the powertrain and emission control systems. When a fault occurs in the powertrain or emission control system, potentially causing carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), or fuel evaporation pollution levels to exceed set standards, the malfunction indicator lamp (MIL) will illuminate as a warning.
I drive an Octavia myself and have plenty of experience locating the OBD port. It's on the driver's side left – just bend down to look below the steering wheel, above the accelerator pedal towards the inner side. You'll find the 16-pin connector after opening that black plastic cover, which usually gets hidden by the lower edge of the dashboard. This port isn't just for reading fault codes; you can also connect HUD displays or tire pressure monitoring devices. A reminder: always turn off the engine and disconnect power before operation – last time I triggered error codes by not paying attention. The position is quite well-designed, easily reachable when installing devices yourself, but don't let cables dangle loosely to interfere with brake pedals.
The OBD port location on the Octavia is very fixed. You can easily find it by looking down near the driver's seat, right below the steering wheel close to the knee area. If you carefully observe the bottom of the dashboard, there's a small flip cover with a clip - opening it reveals the standard 16-pin port. I frequently use this port for diagnostics during repairs, and its position is more convenient than many other vehicles. It works perfectly for connecting diagnostic tools or OBD dash cams, but avoid leaving devices plugged in for extended periods to prevent battery drain. Note that the surrounding space is limited, so be cautious when plugging/unplugging devices to avoid scratching your hands.
