I have bought a 150k mile, t5 84bhp van on a 14 plate as a project. I know it needs work and I got it cheap. I have only driven it on the test drive and then had it delivered as I want to do work on it before I insure it and use it. When I started it tonight from cold there was a rattle or knocking noise from underneath that goes when I dip the clutch. I have read about clutch and dmf failures so could mine be on its way out? I didnt notice any judder when driving but as I say it was a short drive. It was not like a clutch release bearing noise which is a regular rattle in my expereince but morelike a knocking. Any thoughts?
