Notable Problems with the N47
The main problem with the N47 engine is the timing chain failure. It was observed that the timing chain was overused, which led to wear and tear and eventually chain damage. In addition, repairing this chain failure proved to be very costly. In some cases, the engine had to be replaced completely.
This chain problem is one of the main reasons why BMW had to release a better engine version, the B47.
Other problems that were observed include:
Carbon buildup: The engine is prone to the buildup of carbon in the intake systems, which affects the engine's performance.
Turbocharger failures: The turbocharger in some models failed, especially when the mileage was high.
