Common Weaknesses & Maintenance Notes

However, the N47D20 is not without its weaknesses. The most well-known issue involves the timing chain, located at the rear of the engine, which can stretch or fail prematurely if not serviced correctly—often leading to expensive repairs. Turbocharger wear, EGR valve blockages, and carbon buildup in the intake manifold are other potential concerns, particularly in higher-mileage engines. Additionally, diesel particulate filter (DPF) clogging may occur with frequent short trips or poor-quality diesel. To keep the engine running at peak performance, owners should ensure regular oil changes using BMW-approved 5W-30 fully synthetic oil, maintain proper service intervals, and use high-quality diesel fuel.
