Will a Car Fail MOT with Engine Light On?
The answer to this question is: it depends.
The MOT test is an annual inspection that is required for all cars over three years old in the United Kingdom. The test checks a variety of things, including the car’s emissions, brakes, lights, and tires. If any of these items fail to meet the required standards, the car will fail the MOT.
The engine light is a warning light that is designed to alert the driver to a potential problem with the engine. If the engine light is on, it means that the car’s computer has detected a problem and needs to be checked by a mechanic.
In most cases, a car will fail the MOT if the engine light is on. This is because the engine light is an indication that there is a problem with the car’s emissions system. However, there are some exceptions to this rule.
Exceptions to the Rule
There are a few exceptions to the rule that a car will fail the MOT if the engine light is on. These exceptions include:
- The engine light is on due to a minor fault that does not affect the car’s emissions.
- The engine light has been reset and the car has been driven for a short period of time.
- The car is a diesel vehicle and the engine light is on due to a problem with the particulate filter.
What to Do if Your Engine Light Is On
If the engine light is on, it is important to have the car checked by a mechanic as soon as possible. The mechanic will be able to determine the cause of the problem and recommend the necessary repairs.
If you are planning to take your car for an MOT, it is important to have the engine light checked beforehand. If the engine light is on, it is likely that the car will fail the MOT. By having the engine light checked beforehand, you can avoid the inconvenience and expense of a failed MOT.
