Car guides: faults, warning lights and maintenance
What is wrong with your car, what each warning light means, what maintenance is due and how to prepare the roadworthiness test or a used-car purchase, with safety first.
The guides are available in Spanish only.
Each guide explains the most likely causes of a fault, in order, with what you will notice in each case, what you can safely check yourself and when to stop driving or go to a workshop. The maintenance, roadworthiness test and buying guides follow the same layout: the most important first.
They are written by AI from Dataiao Engine, our knowledge base, and, before being published, go through a second, stricter review and a check by a member of the team. They are general information: the actual cause depends on your car, so use them to arrive at the workshop knowing where you stand.
We do not give fixed prices: what a repair costs depends on the car, the parts and the workshop. For a figure for your car, use the repair cost estimate; for your specific fault, the AI diagnosis.
