A fresh MOT doesn’t mean your car is in perfect health. 👀

An MOT checks whether your car meets the minimum legal safety and environmental requirements at the time of the test.

You can still pass with advisories for worn tyres, brakes, suspension and other components that may soon need replacing.

An MOT is a test. It doesn’t service, maintain or repair your car.

If your MOT or car service is due in Cardiff, get in touch with A1 Diagnostics.
