Common Reasons For National Car Test (NCT) Failure And How To Pass It
March 17, 2023
If you own a car in Ireland, you’re probably familiar with the National Car Test (NCT), a mandatory vehicle inspection that all cars over four years old must undergo. The NCT is designed to ensure that vehicles are roadworthy and safe to drive. If your car fails the NCT, you’ll need to make repairs and have it retested before you can legally drive it on the road again. In this article, we’ll look at some common reasons for NCT failure and provide tips on how to pass it.
Lights and signals
One of the most common reasons for NCT failure is a problem with lights or signals. This can include burnt out bulbs, malfunctioning headlights or taillights, and issues with indicators or brake lights. To avoid this issue, it’s a good idea to regularly check your lights and signals and replace any burnt out bulbs as soon as possible.
Suspension and steering
Issues with suspension and steering are another common cause of NCT failure. This can include worn out shock absorbers, damaged ball joints, and problems with the power steering system. To prevent this, it’s important to have your car’s suspension and steering components checked regularly by a qualified mechanic.
The brakes on your car are one of the most important safety features, so it’s no surprise that problems with brakes can lead to NCT failure. This can include worn brake pads or discs, damaged brake lines, or problems with the brake booster or master cylinder. To keep your brakes in good condition, it’s important to have them checked regularly and to replace any worn or damaged components.
Another common reason for NCT failure is high emissions. This can be caused by a variety of factors, including a faulty oxygen sensor, a clogged catalytic converter, or a malfunctioning fuel injection system. To keep your car’s emissions under control, it’s important to have it regularly serviced and to address any issues as soon as they arise.
Finally, issues with tyres can also cause NCT failure. This can include worn tyres, tyres that are the wrong size, or tyres that are not properly inflated. To avoid this, it’s important to regularly check your tyres and replace them when they become worn or damaged. It’s also important to make sure that your tyres are the correct size and are inflated to the correct pressure.
Tips for passing the NCT:
Regularly maintain your car and have it serviced by a qualified mechanic.
Check your lights, signals, suspension, steering, brakes, and tyres regularly.
Replace any worn or damaged components as soon as possible.
Make sure that your car’s emissions are within acceptable levels.
If you’re unsure about any aspect of your car’s condition, have it checked by a professional before the NCT.
Be prepared for the NCT by reviewing the NCT manual and ensuring that your car meets all the requirements.
If your car does fail the NCT, don’t panic. Take note of the issues and have them fixed by a qualified mechanic before retesting.
