Have your vehicle tested with ACL Diagnostic Center
The Diagnostic Center service gives you access to a wide range of tests carried out by professional mechanics. For example, you can have your vehicle tested before a technical inspection, or have your car diagnosed before you leave on holiday. It’s also a popular service for reassuring buyers and sellers of used vehicles.

Tyre and Lighting Campaign
In partnership with Sécurité Routière, ACL is organising a major prevention campaign to check your vehicle’s tyres and lights.

During the winter months, certain climatic factors can make driving more difficult. Falling temperatures, slippery roads… ACL is here to help you ensure that your car is ready for the cold season.
For a month, from mid-October to mid-November, our experts will offer you an assessment in various areas. We check the age, profile and general wear and tear of your tyres to ensure that they are ready for ice, leaves and snow.
The condition of your lights is also crucial. It is important that you can see and be seen during the winter months. ACL will check the functionality of your bulbs (dipped beam, fog lights, parking lights, etc.). Headlight lenses and reflectors will also be inspected.
Finally, battery performance can also be affected when the temperature drops below ten degrees, as the cold slows down the chemical reaction that supplies power to your vehicle’s electrical components. That’s why the experts at ACL also recommend a battery check to ensure you have the best chance of a smooth winter on the road.
Check our events calendar regularly to keep up to date with these and other events.
