Understanding MOT defects and advisories

Date: 25th February 2019

It can be stressful and frustrating if your car fails the MOT or there are a number of defects and advisories, particularly if your car seemed to be in good order prior to the test. Often, the MOT will disclose safety issues that don't necessarily affect the day to day driving and therefore may have gone unnoticed.

Since May 2018, the way that defects are noted during an MOT test changed. Defects found during the MOT test are now categorised as either dangerous, major, minor or advisory.

The category the MOT tester gives each item will depend on the type of problem and how serious it is. Dangerous and major defects are considered to be detrimental to the vehicle’s safety, put other road users at risk or have an impact on the environment, these defects will result in an instant fail and must be repaired immediately. Minor defects are considered to have no significant effect on the safety of the vehicle but should be repaired as soon as possible, and advisories are things that should be monitored and are likely to require attention in the near future.


At BP Rolls MOT & Service Centre we know that customers are often sceptical about defects and advisories, so we have taken steps to improve the transparency of reporting. As well as talking you through any issues we discover, we also use Citnow to enable our Technicians to share a video with you, so you can see exactly what they see while your car is in the workshop. We hope that using this technology will help us to build trusting relationships with our customers and give you a better understanding of the condition of your car, empowering you to make an informed decision about any repairs.


We understand that vehicle repairs can be costly, and when they come out of the blue can be tricky to budget for, but we want you to be reassured that our brand promise is to always communicate clearly exactly what we believe is required to maintain the safety and reliability of your vehicle, but we will never advise you to do anything that is unnecessary or try and sell you parts that you don’t need. Ultimately the choice is yours so we want to make sure that you have enough information in order to decide, so please do not hesitate to ask questions or request a further explanation if there is anything you are not clear on. We are here to help.


If your vehicle has failed its MOT test, and you need guidance on repairing defects, you are welcome to speak to one of our customer advisors or qualified
technicians for advice. Just call 01264 335801.
