qube 3570 Report post Posted February 11, 2021 I have a friend looking at a 2012 X1 20d, N47b20 engine. Quick google shows timing chain failure.. eek! Is it really that bad or an internet myth? Any common/potential issues with this model? Ideally would like the facelift 2L petrol with the N20 engine but they seem to be very rare.. Quote Share this post Link to post Share on other sites
Spudooli 18 Report post Posted February 11, 2021 I only know a single person that had an N47 in their X3 and their timing chain broke. So that makes a 100% failure rate that I know of. If that stat is any use to you? 1 Quote Share this post Link to post Share on other sites
