What's causing my diesel Focus to rattle so much?
I own a Ford Focus from 2008, with the 1.6 diesel engine. A while back I started hearing some strange noises from the engine. These noises are similar to what you hear on a car with a faulty DMF, a rattle which starts from low revs. However, I do not think the rattle is DMF related because I am not experiencing variations at idle. Can you offer any help to locate the problem?

Well if it was the DMF you should be able to hear a change in the noise/rattle when you depress and then release the clutch pedal. So is the engine running okay at idle and through up as you accelerate, because it may be a misfire at low revs that is causing vibrations.
You may want to check all pipes/connections in the engine bay and also check that the exhaust system has not come loose/rattling.
