A steady ABS warning light on your Octavia IV usually points to a wheel speed sensor, wiring, or encoder ring fault. Here’s what to check first and when it’s safer to stop driving.
What the ABS light is telling you
If your Škoda Octavia IV keeps the ABS warning light on after startup, the ABS module has logged a fault and disabled the system. On this car, the most common culprit is a wheel speed sensor or its magnetic encoder ring, but it can also be a wiring or connector issue, a damaged bearing, low voltage, or an ABS control unit problem. The light staying on continuously — rather than flickering — usually means the fault is current and stored, not intermittent. A proper diagnostic scan of the ABS module is the fastest way to see which wheel is affected and what the signal is doing.
