428i timing chain
My N20 is at 78000 miles and no timing chain issues. My mechanic says wait until the idiot light goes on. Supposedly you can look into the oil filler and see the chain and the plastic guide-and tell if it's wearing-if you know how to identify that-I don't. He also said if there is a start-up chatter that goes away once warm-that's a telltale sign of a loose timing chain. I read to do the change preemptively, but he warned me away from that due to the expense. My 428i sport line is a manual as well, so I'm just going to wait. Hope for no catastrophe!!!!
