How to read MOT advisory notes: what each one actually means

MOT advisory notes are important indicators of your vehicle’s condition, highlighting areas that may require attention but are not critical for passing the test. Understanding these notes can help you prioritise repairs and maintain your vehicle’s safety and performance.

What are MOT advisory notes?

MOT advisory notes are comments made by the tester during the MOT inspection, indicating parts of the vehicle that are not currently failing but may need attention in the near future. These notes are designed to inform you of potential issues that could affect the vehicle’s safety, performance, or compliance with regulations.

While advisory notes do not prevent your vehicle from passing the MOT, they serve as a warning to address these issues to avoid future problems or failures. Keeping an eye on these advisories can help you maintain your vehicle in good condition and potentially save money on repairs down the line.

Common advisory phrases explained

One of the most common phrases you may encounter in an MOT advisory note is “bushes deteriorated.” This refers to the rubber or polyurethane components that connect various parts of the suspension system. Deterioration can lead to increased wear on other suspension components and affect handling.

While it may not require immediate action, it is advisable to monitor the condition of the bushes and consider replacing them if they show significant wear. Ignoring this advisory could lead to more expensive repairs if other suspension components are damaged as a result.

Understanding brake disc advisories

Another frequent advisory you might see is “discs pitted.” This indicates that the brake discs have developed surface imperfections, such as corrosion or scoring. While this may not immediately affect braking performance, it can lead to reduced effectiveness over time and increased wear on brake pads.

It is important to keep an eye on the condition of your brake discs. If they become excessively pitted, it may be necessary to replace them to ensure optimal braking performance. Regular checks can help you avoid a situation where your brakes fail to perform when you need them most.

Tyre wear advisories

Advisories related to tyre condition, such as “tyre worn close to limit,” are crucial for safety. This phrase means that the tread depth on the tyre is approaching the legal limit of 1.6mm. Tyres with insufficient tread can significantly affect grip, especially in wet conditions, increasing the risk of accidents.

If you receive this advisory, it is essential to replace the affected tyres promptly. Driving on worn tyres not only compromises safety but can also lead to penalties if caught by law enforcement. Regularly checking tyre tread depth can help you stay safe on the road.

Exhaust system advisories

Advisories regarding the exhaust system, such as “exhaust emissions high,” indicate that the vehicle’s exhaust may not be functioning optimally. This could mean that the vehicle is producing more emissions than allowed, which can lead to environmental concerns and potential fines.

While this advisory may not require immediate action, it is wise to have the exhaust system checked. A poorly functioning exhaust can also affect engine performance and fuel efficiency. Addressing this issue sooner rather than later can help you avoid more significant problems down the line.

General maintenance advisories

Other common advisory notes may include phrases like “oil leak” or “light bulbs dim.” These notes indicate that while the vehicle is still operational, there are issues that could affect its performance or safety. An oil leak, for example, can lead to engine damage if not addressed, while dim light bulbs can reduce visibility at night.

It is advisable to take these advisories seriously and schedule repairs as needed. Regular maintenance can help you avoid more costly repairs in the future and ensure your vehicle remains safe and reliable on the road. Keeping a close eye on these notes can contribute to the longevity of your vehicle.
