Why does my BMW X3 constantly display an ABS warning light?

I recently purchased a used BMW X3 and noticed that the ABS warning light seems to be always on. What could be causing this issue and how can I fix it?

The ABS warning light can indicate several possible issues, including a faulty ABS sensor or a malfunctioning ABS control module. It is important to have the vehicle properly diagnosed by a certified mechanic to determine the exact cause of the problem.

In some cases, a low battery voltage can trigger the ABS warning light. Try charging or replacing your battery to see if the light turns off.
