New to forums and new to BMW.
I recently bought my first BMW - an 08 plate 318 se diesel touring (in June) and have started to get a rattle on cold start up. I sent it back to the (non BMW) dealer who has since told me that this is a timing chain problem? . Aparently BWM were aware of a fault on this model and developed a new modified sprocket that the chain runs around. This aprarently causes excessive ware. The problem is that it is out of warranty and not purchased through a BMW dealer. I am told that to replace the chain involves taking the whole engine out ........can anyone help / provide any pointers or advice? is anyone esle aware that BMW know about this problem with the timing chain?
