Technical control: checkpoint and possible failures

Do every 2 years technical control is a must and essential intervention for your vehicle. Indeed, if you are traveling with vehicle without technical control indeed you risk Finesor even immobilization of the car. Therefore, it is important that you follow your service manual to ensure that your technical inspection is validated the first time.

?? What are technical control checkpoints?

Le technical control has at least 133 checkpoints grouped around 9 main functions:

• Visibility (windshield, mirrors, fogging system, wipers, etc.);
• Troubles (fluid leak, muffler, exhaust, smoke, etc.);
• Vehicle identification (license plate, serial number on the chassis, etc.);
• Lanterns, reflective devices and electrical equipment (battery, light control, opacity of optics, etc.);
• Axles, wheels, tires and suspension (wheels, shock absorbers, wheel bearings, tire condition, etc.);

?? How much does it cost to pass technical control?

Le price technical control not regulated by law, which means that every garage owner is free to apply the rate they want. Count on average between 50 and 75 € for a gasoline vehicle and between 50 and 85 € for a diesel car.

On the other hand, technical control is more expensive for an electric vehicle: count between 90 and 120 €... Do not forget to return your registration card, because the garage will ask you to provide it to confirm your technical control.

Now you know everything about technical control! Keep in mind that the best way to go directly to the MOT without a return visit is to regularly and properly service your car. Indeed, car maintenance should be carried out continuously, and not just before technical control.
