What is an electronic car diagnostic?

It’s connecting a specialised computer to your car’s ECU to read error codes and real-time data. Modern cars have sensors that detect problems and store the information. At our Dénia garage we read and interpret it with professional equipment.

Why is the engine warning light on?

It can be caused by many things: from a faulty oxygen sensor to serious engine problems. Don’t ignore it. Sometimes it’s minor, but other times it indicates a fault that could damage the engine if you keep driving. Come to our Dénia garage for a quick diagnostic.

How much does a car diagnostic cost in Dénia?

Electronic diagnostics at our Dénia garage are competitively priced. If you decide to have the repair done with us, we deduct the diagnostic cost. So you only pay for the solution, not for finding the problem. Call us for details.

How long does a car diagnostic take?

A basic diagnostic takes 30-45 minutes. If the problem is complex and requires further testing, it may take longer. We’ll let you know the estimated time at our Dénia garage.

Can you clear the engine warning light?

Yes, we can clear it, but if the underlying problem remains, it will come back on. The important thing is to find the root cause and fix it. Clearing the light without repairing serves no purpose. At Motorplus Dénia, we diagnose and repair.

Do you work with all car makes?

Yes, our diagnostic equipment in Dénia is multi-brand and works with all European, Asian and American makes. From Volkswagen to Toyota, Ford to BMW.
