ABS sensor failure

So it seems these things happen in threes! The ABS sensor light came on the dash for the second time in my ownership. This means parts of the ABS system is not working and so the system is deactivated. Typically it is an ABS sensor on one of the wheel hubs that has failed and needs replacing. While the light is on, the ABS system will not be functioning, so be aware that you are likely to lock up the wheels under heavy braking especially in wet conditions.

Replacing an ABS sensor is quite a straightforward job and can save you money on garage bills if you choose to do it yourself. All you need are some basic tools, and ideally a sturdy vice clamped to a bench or similar.

To diagnose which ABS sensor is at fault and how to replace it, I’ve written a guide here to talk you through the process.
