Past MOT Advisories: Your Pre-MOT Checklist

The annual MOT test is a cornerstone of vehicle safety and roadworthiness in the UK, ensuring that cars meet minimum environmental and safety standards. While many drivers focus solely on passing or failing, a crucial yet often overlooked aspect of the MOT process lies in the 'advisories' issued during previous tests. These aren't outright failures, but they are warnings from the examiner about components that could become a serious problem in the future. Ignoring them is a common mistake that can lead to costly repairs, unexpected failures, and even compromise your safety. Understanding and proactively addressing your past MOT advisories is not just good practice; it's a smart, cost-effective strategy for vehicle maintenance and ensuring a stress-free next MOT.

What Exactly Are MOT Advisories?

An MOT advisory is a note made by the examiner about a component that is nearing the point of requiring repair or replacement, but isn't yet a significant enough defect to warrant a 'major' or 'dangerous' fail. Think of them as a 'heads-up' or a 'watch list' for your vehicle. They indicate items that are worn, slightly damaged, or showing early signs of deterioration. For example, a tyre that has legal tread depth but is close to the minimum limit might receive an advisory. Similarly, minor corrosion on a brake pipe that isn't yet compromising its integrity could also be noted.

It's important to differentiate advisories from the actual pass/fail criteria. If an item receives an advisory, your vehicle still passes the MOT test. However, the advisory serves as a strong recommendation that these issues should be monitored and, ideally, rectified before they escalate into something more serious. The key is that these are not immediate failures, but rather potential future problems that the examiner deems worthy of your attention.

The Difference Between Advisories, Minor, Major, and Dangerous Faults

Understanding the new MOT fault categories, introduced in May 2018, is vital:

• Advisory: A component that works but shows signs of wear and tear, or is nearing the end of its life. Not a fail.
• Minor Fault: A defect that is not immediately dangerous but could become so. The vehicle passes, but the fault should be rectified soon.
• Major Fault: A defect that could affect the vehicle's safety, impact the environment, or cause other road users to be at risk. This is an MOT fail.
• Dangerous Fault: A defect that poses a direct and immediate risk to road safety or has a serious impact on the environment. This is an MOT fail, and the vehicle should not be driven until repaired.

Advisories are at the bottom of this hierarchy, but they are often the precursor to minor, major, or even dangerous faults if left unaddressed. A proactive approach to advisories can prevent these escalations.

Why Checking Past Advisories is Indispensable

Ignoring previous MOT advisories is akin to ignoring early warning lights on your dashboard. While it might seem convenient at the time, it often leads to bigger headaches and expenses down the line. Here are compelling reasons why reviewing your past advisories is an indispensable part of your pre-MOT routine:

1. Preventing Future MOT Failures

The most straightforward reason is to avoid failing your next MOT. An advisory noted one year, such as 'tyres nearing legal limit' or 'slight play in suspension bush', is highly likely to have progressed by the following year. What was an advisory last time could easily become a 'minor' or 'major' fault this time, resulting in an immediate failure. By addressing these issues beforehand, you significantly increase your chances of a first-time pass.

2. Saving Money in the Long Run

Addressing an advisory while it's still a minor issue is almost always cheaper than waiting for it to become a major fault. For instance, replacing a worn brake pad before it starts grinding against the disc will save you the cost of also replacing a damaged brake disc. Similarly, catching a small exhaust leak early might only require a minor repair, whereas waiting could mean a full exhaust system replacement. Preventative maintenance is key to long-term savings.

3. Enhancing Vehicle Safety

Many advisories relate directly to safety-critical components like brakes, tyres, steering, and suspension. While not an immediate danger, a worn component can compromise your vehicle's handling, braking efficiency, or stability, especially in emergency situations. For example, worn suspension bushes can affect steering precision, and thinning brake discs can increase stopping distances. Addressing these issues ensures your vehicle remains as safe as possible for you, your passengers, and other road users.

4. Understanding Your Vehicle's Health

Regularly reviewing advisories gives you a much clearer picture of your vehicle's overall condition and typical wear patterns. It helps you identify recurring issues or areas that might require more frequent attention. This knowledge empowers you to make informed decisions about maintenance and repair, potentially extending your vehicle's longevity.

5. Avoiding Unexpected Breakdowns

While an advisory isn't a direct cause for breakdown, neglecting components flagged by an advisory increases the likelihood of an unexpected failure. A suspension component that was advised for slight play could eventually fail completely, leaving you stranded. Proactive repairs based on advisories can help you avoid inconvenient and potentially dangerous breakdowns.

How to Access Your Past MOT History

Fortunately, accessing your vehicle's past MOT history, including all advisories, is incredibly easy and free. The UK government provides an online service for this purpose:

You will need your vehicle's registration number (number plate) and its make and model. Simply visit the official Gov.uk website for 'Check the MOT history of a vehicle'. This service will display all past MOT results, including pass/fail status, mileage recorded at the time of the test, and a detailed list of any advisories, minor, major, or dangerous faults noted.

Common MOT Advisory Categories and What They Mean

Advisories can cover a wide range of vehicle components. Understanding the most common ones and their implications will help you prioritise repairs.

1. Tyres

Common Advisories: 'Tyres nearing legal limit', 'Slight cracking to tyre sidewall', 'Tyre worn on edge'.
Implications: Reduced grip, increased stopping distances, higher risk of aquaplaning, potential for blowouts. Tyres are fundamental to safety.
Action: Monitor tread depth regularly. Replace tyres if tread depth approaches 1.6mm across the central three-quarters of the tread and around the entire circumference. Address cracking promptly as it indicates age and material degradation.

2. Brakes

Common Advisories: 'Brake pads wearing thin', 'Brake disc slight corrosion/pitting', 'Brake pipes showing signs of corrosion'.
Implications: Reduced braking efficiency, uneven braking, potential for brake failure.
Action: Have pads and discs inspected by a mechanic. Slight corrosion on discs can sometimes clear with use, but pitting indicates significant wear. Brake pipe corrosion needs professional assessment as it can lead to fluid leaks and total brake failure.

3. Suspension

Common Advisories: 'Slight play in suspension bush', 'Coil spring light corrosion', 'Dampers slightly weeping'.
Implications: Reduced handling, poor ride comfort, uneven tyre wear, compromised stability, especially during cornering or braking.
Action: Bushes can deteriorate, leading to knocking noises and reduced control. Coil spring corrosion can lead to snapping. Weeping dampers (shock absorbers) indicate they are losing fluid and effectiveness, impacting ride and handling. Professional inspection is highly recommended for all suspension issues.

4. Lights

Common Advisories: 'Headlamp slightly out of aim', 'Light lens slightly cracked'.
Implications: Reduced visibility for the driver, dazzling other road users, potential for moisture ingress leading to electrical issues.
Action: Headlamp aim can often be adjusted. A cracked lens should be replaced to prevent water damage to the bulb and wiring.

5. Exhaust System

Common Advisories: 'Exhaust mounting slightly loose', 'Exhaust pipe light corrosion'.
Implications: Increased noise, potential for exhaust fumes to enter the cabin, environmental impact (emissions), increased risk of components falling off.
Action: Loose mountings can often be tightened or replaced. Light corrosion can progress to holes, leading to an MOT fail. Early repair can save the cost of a full exhaust system.

6. Steering

Common Advisories: 'Slight play in steering rack/ball joint'.
Implications: Reduced steering precision, vague steering feel, potential for loss of control.
Action: Any play in steering components should be investigated and rectified by a professional, as it directly impacts your ability to control the vehicle safely.

7. Bodywork and Chassis

Common Advisories: 'Underbody light corrosion', 'Minor damage to bodywork with sharp edge'.
Implications: Structural weakening over time, safety hazard to pedestrians or other vehicles.
Action: Light corrosion can be treated and protected. Sharp edges should be filed down or repaired to prevent injury.

Prioritising and Addressing Advisories

Not all advisories carry the same urgency. While it's ideal to address all of them, some require more immediate attention than others, particularly those affecting safety and performance.

Prioritisation Table:

For high-priority advisories, it is highly recommended to seek professional attention as soon as possible. For medium and low-priority items, you can often monitor them or plan for repairs during your next service.

DIY vs. Professional Mechanic

Some advisories, like a loose exhaust mounting or a simple bulb replacement (not an advisory but a common issue), might be manageable for a competent DIY enthusiast. However, for anything related to brakes, steering, suspension, or complex electrical systems, it is always best to consult a qualified mechanic. These systems are critical for safety, and incorrect repairs can have dire consequences. A professional can accurately diagnose the extent of the issue and ensure repairs are carried out to the correct standards.

Frequently Asked Questions About MOT Advisories

Q1: Do advisories automatically fail me on my next MOT?

A: No, an advisory itself does not mean an automatic fail. However, an advisory indicates an item that is worn or deteriorating. If left unaddressed, it is highly likely that the issue will have progressed by your next MOT and could then be classified as a 'minor', 'major', or 'dangerous' fault, leading to a fail.

Q2: How long do advisories stay on my vehicle's MOT history?

A: Advisories, along with all other MOT results, remain on your vehicle's digital MOT history indefinitely. They are a permanent part of the vehicle's record.

Q3: Can I appeal an MOT advisory?

A: You cannot formally appeal an advisory in the same way you can appeal an MOT failure. Advisories are the examiner's professional opinion on items that require attention. If you strongly disagree, you could seek a second opinion from another garage, but there's no official appeal process for advisories.

Q4: Is it legal to drive a car with MOT advisories?

A: Yes, it is perfectly legal to drive a car with advisories, as long as the vehicle has passed its MOT and does not have any 'major' or 'dangerous' faults. However, for your safety and to prevent future issues, it is strongly recommended to address advisories promptly.

Q5: Should I fix all advisories, even minor ones?

A: While not strictly necessary for an immediate pass, it is always advisable to fix all advisories. Addressing them early is part of good vehicle maintenance, improves safety, and is typically more cost-effective than waiting for the issue to worsen and become a major repair or an MOT failure.

Q6: Will addressing an advisory remove it from my MOT history?

A: No, even if you fix the issue, the advisory will remain on your vehicle's historical MOT record. However, if the item is re-examined at a subsequent MOT and found to be in good condition, it will not receive the same advisory again. The record simply shows what was noted at each specific test.

Conclusion

The MOT advisory system is a valuable tool designed to help vehicle owners maintain their cars safely and efficiently. By taking a few minutes to check your past MOT advisories online, you gain valuable insight into your vehicle's condition, allowing you to be proactive with maintenance. This simple step can prevent unexpected MOT failures, save you money on costly retests and repairs, and most importantly, ensure your vehicle remains safe and reliable on the road. Don't let those little notes turn into big problems; make reviewing your past advisories an essential part of your annual pre-MOT routine.
