As some of the members here are mechanics I have a question for them (if possible of course), when switching off the engine of my Td4 MY01 I regularly hear a kind of spinningdown noise which I took on video and can be heard when going to the link below. I narrowed it down as probably being caused by the fact my EGR-valve is put out of service. (Last week I put it to work again and didn't hear that noise during that whole week). My question now is, what can cause this kind of noise pse? Is it indeed EGR related ? (Mine disconnected for years already, my neighbour who owns a Td4 Sport of 2005, also with EGR blocked, has the same spindown noise as I noticed it last week when he came to see me).
Thanks for possible answers and take care.
