Terms of use

OBDwiki is a guide, not a mechanic. It helps you understand fault codes and points you towards the most likely cause and the cheapest test to rule it in or out. It doesn't replace a qualified mechanic's own diagnosis of the vehicle in front of them, and it never gives you steps for a job we've marked as garage-only. See the Safety notice.

We measure the accuracy of the write-ups we publish and aim for at least 98% correct, but we don't guarantee any individual answer is right for your car. Use your own judgement, and stop if anything feels wrong.

The tools on OBDwiki are free to use today. No account is required for anything that currently works.

The company operating OBDwiki, its registered details and the governing law of these terms will be added here once they're finalised.

These terms may change as the site grows. This page always shows the version that applies right now.
