Every vehicle in the UK must pass the Ministry of Transport (MOT) test annually once it reaches three years of age. The MOT test ensures that vehicles meet road safety and environmental standards. Unfortunately, many cars fail their MOT due to preventable issues.
By understanding the common causes of MOT failures, you can take proactive measures, such as pre-MOT checks at A3E Auto, to increase the likelihood of passing the test. Let’s delve into the top reasons vehicles fail and how you can avoid these setbacks.
Faulty Lights and Indicators
Lighting issues are among the leading causes of MOT failures. Defective headlights, brake lights, indicators, and number plate lights can all result in failure. This is primarily due to bulbs burning out or wiring faults.
How to Avoid Lighting-Related Failures
- Regularly inspect all lights for functionality.
- Replace burned-out bulbs promptly.
- Check for signs of dimming or flickering, which may indicate wiring issues.
- Conduct a pre-MOT check at A3E Auto to ensure all lighting systems are in top condition.
Worn-Out Tyres
Tyres are crucial for road safety, and their condition is heavily scrutinized during an MOT. Common issues include tread depth below the legal minimum of 1.6mm, bulges, and visible damage.
Tips to Prevent Tyre-Related MOT Failures
- Measure tyre tread depth regularly with a gauge.
- Inspect tyres for cuts, bulges, or uneven wear patterns.
- Ensure tyre pressure matches the manufacturer’s recommendations.
- Visit A3E Auto for a thorough tyre inspection as part of your pre-MOT service.
Damaged Windscreen and Wipers
Visibility is key to safe driving. A cracked windscreen or faulty wipers can lead to an MOT failure. Chips larger than 10mm in the driver’s view or 40mm in other areas of the windscreen are considered hazardous.
How to Ensure Your Windscreen and Wipers Are MOT-Ready
- Repair chips and cracks on your windscreen promptly.
- Replace worn or torn wiper blades to ensure they clean effectively.
- Check washer fluid levels and top up if needed.
- During a pre-MOT check at A3E Auto, experts can identify and fix potential issues.
Brake System Problems
Faulty brakes are not only an MOT failure point but also a severe safety risk. Common brake issues include worn brake pads, leaking fluid, and imbalanced braking forces.
Steps to Avoid Brake-Related Failures
- Listen for unusual noises such as squealing or grinding, which may indicate worn pads.
- Check for warning lights on the dashboard.
- Regularly test brake responsiveness and pedal firmness.
- Book a comprehensive brake check at A3E Auto before your MOT test.
Exhaust Emissions Issues
Stricter regulations on emissions mean that vehicles with excessive exhaust emissions often fail their MOT. This is particularly common in older cars with deteriorating catalytic converters or diesel particulate filters (DPFs).
How to Keep Emissions in Check
- Use high-quality fuel and consider adding fuel additives to reduce emissions.
- Ensure the catalytic converter and DPF are in good condition.
- Get your vehicle serviced regularly to maintain engine efficiency.
- A3E Auto offers advanced diagnostic tools to ensure your vehicle meets emission standards.
