Are BMW N47 engines still susceptible to timing chain failure?
I've read all about the dreaded timing chain failure on 320d/520d BMWs with N47 engines manufactured between 2007 and 2011. I wanted to know if models after March 2011 (when they supposedly changed the engine) have fixed this problem?
Also on this model, is the timing chain still at the back of the engine or the front?

Still at the back of the engine. Have not heard of any post 2011 failure. But the main reason for the failures was BMW's longlife servicing. Any oil will get contaminated by 20,000 miles and start to block oilways. Every engine needs an oil and filter change at least every 10,000 miles or every 12 months whichever comes first.
