Hi Lads, My 2011 F10 520D A, has developed a noise. When I start it cold I hear a sound, a bit like a loose chain but not sure. It goes out of it after a few seconds, As if the tesioner was lazy. But then when I drive for the first few miles, usualy until the engine heats up there is a rattle from the engine, Like a labouring sound as if the wrong gear were selected in a manual box. Theres 128k KM on the clock , Oil was changed about 2 weeks ago but the noise has been there for a couple of months now. Does this sound like the timing chain fault with the N47 engine, Has anyone here experienced this problem? I took out an extended warranty policy when I bought it 13 onths agok. Im not too sure if the chain repar is covered though, Im trying to research it before I go and tackle the dealer {non BMW} about it.
Thanks.
