Your MOT isn’t just a yearly formality. It’s the government’s way of making sure your car is safe, road-legal, and environmentally compliant. But every year, thousands of vehicles fail their MOT for surprisingly simple reasons.
If your car has recently failed or you’re preparing for your next test, this guide will help you understand what went wrong and where to find expert MOT failure repair in Aldershot.
Understanding Why Cars Fail MOT Tests
An MOT failure means your car has one or more defects that make it unsafe or non-compliant with DVSA standards. These defects are divided into three categories:
- Dangerous Defects: Serious safety issues such as brake failure or severely worn tyres. The car cannot be driven until repaired.
- Major Defects: Faults that cause a fail but may still allow limited driving to a pre-booked repair.
- Minor Defects: Not severe enough to fail the MOT, but still require attention soon.
Knowing which category your fault falls into helps you act quickly and safely.
Common Reasons Cars Fail MOT Tests
1. Lighting and Electrical Faults
The most frequent MOT failure cause in the UK is faulty lighting. Headlights, brake lights, indicators, and number plate lamps are often overlooked, yet they account for nearly a fifth of all MOT fails. A simple pre-test inspection, walking around your car and checking all bulbs, can prevent an unnecessary fail.
2. Suspension Problems
Aldershot’s local roads, with their speed bumps and uneven surfaces, can take a toll on suspension components. Broken springs, leaking shock absorbers, or worn bushings cause instability and poor handling, leading to MOT failure. Any knocking noises or uneven ride height are early warning signs.
3. Brake System Defects
Worn brake pads, corroded discs, or imbalanced braking systems are major safety concerns. During an MOT, testers measure braking efficiency and pedal response. Even a small leak or sticking caliper can cause a fail. Because braking issues are classed as “major” or “dangerous,” immediate repair is always advised.
4. Tyres and Wheels
Tyres are among the easiest yet most vital parts to check. The legal tread depth is 1.6mm, but many drivers fail because they don’t notice uneven wear, sidewall bulges, or embedded debris. Driving through Hampshire’s varied terrain means tyres wear differently across vehicles, so regular checks are essential. MOT testers also inspect wheel integrity and tyre pressures.
5. Visibility and Windscreen Damage
A clear view of the road is non-negotiable. MOT failures often result from cracked windscreens, worn wipers, or washer jets not functioning. Even stickers or dashboard clutter in the driver’s line of sight can lead to rejection. Before your test, ensure washer fluid is topped up and blades are clean and even.
6. Exhaust and Emissions
With stricter emissions rules, exhaust leaks or a failed catalytic converter can easily trigger a fail. Diesel vehicles, in particular, face tougher checks under smoke-density regulations. If your car’s check-engine light stays on, get diagnostics done before your MOT.
What to Do After an MOT Failure?
When your vehicle fails, you’ll receive a VT30 refusal certificate listing the faults. Here’s what to do next:
- Read the certificate carefully: It tells you exactly why you failed and which parts are unsafe.
- Decide on repair options: Some faults can be repaired immediately on-site. Others might need parts or specialist work.
- Check for retest eligibility: If you leave the car at the same garage and repairs are completed within ten working days, you often get a free partial retest.
- Avoid driving a dangerous vehicle: If marked as “dangerous,” driving it could result in fines or penalty points.
Preventing MOT Failure: Simple Pre-Test Checks
You can avoid most MOT issues with ten minutes of preparation:
- Check all exterior lights and replace any blown bulbs.
- Top up washer fluid and ensure wipers clean without streaking.
- Inspect tyres for tread depth, even wear, and correct pressure.
- Make sure mirrors and number plates are clean and securely fixed.
- Clear the dashboard of warning lights.
These basic checks can save time, money, and frustration on test day.
