How do I fix the ABS system on my Vauxhall Astra?

My ABS light is constantly on and I'm not sure what to do. Is this a simple fix or should I take it to a mechanic?

Firstly, try checking the ABS sensors and cleaning them if they are dirty or covered in debris. If that doesn't work, it could be a faulty ABS module which would require a mechanic's attention.

Another possible cause could be low brake fluid levels. Check the reservoir and top up if necessary. If the light continues to stay on, it's best to have a professional check it out.

In some cases, the issue could be with the ABS fuse. Check the fuse box and replace any blown fuses. However, if the issue persists, it could be a more complex problem that requires expert diagnosis.
