If your Volvo V40's engine won't shut down after removing the key, it could be due to a faulty ignition switch, a stuck relay, or an issue with the engine control module. Check for any electrical short circuits or malfunctioning components that might be keeping the ignition circuit engaged. Additionally, ensure that the key fob isn't malfunctioning or causing the system to stay active. If the problem persists, it's advisable to consult a professional mechanic for a thorough diagnosis.
