The BMW 328d, a diesel-powered variant of the popular 3 Series, offered a compelling blend of performance and fuel efficiency. For those seeking a used BMW with excellent mileage and a sporty driving experience, the 328d is an appealing option. However, like any vehicle, some model years are more reliable and desirable than others. This guide will explore the best 328d years to consider and which ones to avoid, providing valuable insights for potential buyers.

BMW 328d Model Years: A Quick Overview

Model Year Notable Features & Potential Issues Reliability Score (Out of 5)
2014 First year of production. Potential for early production issues. Known for good fuel economy and strong torque. EGR cooler issues were common. 3.5
2015 Minor improvements over 2014. Continued good fuel economy and torque. EGR cooler issues remained a concern. Some reports of timing chain issues surfaced. 3.7
2016 Further refinements and improvements. Still retained the excellent fuel economy and performance. EGR cooler issues persisted but with potentially improved parts. 4.0
2017 Considered by many to be the most reliable year. BMW addressed many of the earlier issues. Still provided the same great fuel economy and performance. Fewer reported EGR cooler problems. 4.3
2018 Last year of production for the 328d. Very similar to the 2017 model. Continued reliability improvements. EGR cooler issues were less prevalent. Potentially higher prices due to being the final model year. 4.2

Detailed Explanations

2014: As the inaugural year for the 328d, the 2014 models introduced the N47 diesel engine to the 3 Series lineup in the US market. While lauded for its impressive fuel economy and strong low-end torque, early production examples were susceptible to various issues, most notably the EGR cooler failures. The EGR (Exhaust Gas Recirculation) cooler is responsible for reducing NOx emissions, and its failure could lead to coolant leaks and potential engine damage. Other potential concerns included minor software glitches and trim imperfections typical of a first-year model.

2015: The 2015 model year saw some refinements to the 328d, but it largely retained the same characteristics as the 2014 version. The fuel economy and performance remained excellent, making it a desirable option for those prioritizing efficiency. However, the EGR cooler issues persisted, and reports of timing chain problems began to surface. The timing chain is a critical engine component, and its failure can result in catastrophic engine damage, making it an expensive repair. Potential buyers should carefully inspect the service history for any signs of timing chain issues.

2016: BMW continued to improve the 328d with the 2016 model year. While the core engine and drivetrain remained largely unchanged, further refinements were implemented to address some of the earlier issues. The EGR cooler problems, although still present, were potentially mitigated by improved parts. This year represents a step up in reliability compared to the 2014 and 2015 models. It's still recommended to check the EGR cooler's condition as part of a pre-purchase inspection.

2017: The 2017 BMW 328d is widely considered the most reliable year for this model. BMW had addressed many of the initial teething problems that plagued the earlier model years. It offered the same attractive combination of excellent fuel economy and satisfying performance. Reports of EGR cooler failures were significantly reduced, and the overall build quality seemed to be improved. This model year represents the sweet spot in terms of reliability and value for many buyers.

2018: As the final year of production for the 328d, the 2018 model is very similar to the 2017 version. It benefits from the accumulated improvements made over the production run, resulting in continued reliability enhancements. EGR cooler issues were even less prevalent in this final year. However, due to its status as the last model year, 2018 328ds may command a slightly higher price on the used market. If you find one in good condition and with a clean service history, it's an excellent choice.
