The N47 engine, used in BMWs from 2007 to 2014, is notorious for timing chain failures due to premature wear, often necessitating a complete engine breakdown as the chain is located at the rear of the engine.M47 vs N47 – Comparison and Conclusions The M47 is an older-generation engine, simpler and more reliable, with a front-mounted timing chain. It is a great choice for those who value reliability and want to avoid costly repairs.The main problems with the N47 timing chain were noted until 2011 although there are still, albeit fewer, reported problems after this. In 2014, BMW replaced the N47 engine with the B47 which uses same chain design but left the poor reputation of the N47 behind.The newer link style of chain is notorious for failing in diesel engines due to soot abrasion. Another thing on the N47/57’s side is rear mounted chain gear.
