I would take it to a BMW dealer. Even though it is far out of warranty, the car is not that old and this kind of thing shouldn't happen. Ask if BMW will cover part of the cost out of good will and questionable design. I disagree with those who say a timing chain needs servicing. If so, why doesn't BMW offer any guidance on it. I also disagree that the guide is plastic in most modern cars. It wasn't on a Nissan VQ. As far as I'm concerned, it should last the life of the car.
