If a check injection warning light comes on Renault Megane 1.5 diesel and its not the coils is it likely to be an injector fault and If so should it pass an MOT?

If the check injection warning light comes on in a Renault Megane 1.5 diesel and the coils are confirmed to be functioning, it is indeed possible that there is an injector fault. This issue can affect the engine's performance and emissions, potentially leading to a failure in the MOT if it results in excessive smoke or other emissions violations. However, if the vehicle still meets the required emissions standards despite the injector issue, it may still pass the MOT. It's advisable to have the vehicle diagnosed to ensure compliance and safe operation.
