Morning all, I've got an annoying rattle / rumble noise from the car when the RPM is just above idle speed and 900rpm. I've looked at what i think would be the obvious things to check; like is the engine cover fitted correctly, are the under trays secure, anything obviously loose but I cant get to the bottom of it. My local garage has also checked suspension / steering components / brakes to make sure theres no safety issues. Has anyone come across this type of thing before. If so, what solved it for you? Any help appreciated, I cant abide squeaks and rattles when driving. They do my head in!!
