Is the BMW diesel engine reliable?
Bmw 3 liter diesel engines are bulletproof. They are very reliable and have great fuel economy. Problematic bmw engines with a reputation for breaking down some specific engine issues have been observed in the bmw 320d 2. Diesel, 520d 2. Diesel, and x5 330d 3. Diesel variants. The bmw 320d 2. Diesel engines, particularly the n47d20a and n47d20c variants, have been prone to timing chain problems.BMW N63 V8 Engine (Oil & Cooling Problems) BMW’s first turbocharged V8, the N63 engine, promised incredible performance but quickly developed a bad reputation. Owners reported excessive oil consumption, failing injectors and cooling system problems, with many engines requiring major work at relatively low mileage.So 200,000 or 300,000km engines are not unusual. That doesn’t mean all diesels necessarily have sound long-term (or even short-term) reliability, but the good ones generally do.The Diesel Workhorses – M57 and N47 These engines have powered a wide range of BMW models, earning a reputation for longevity and robustness, even in demanding conditions.What are the most typical difficulties with the BMW B47 engine? The most typical problems include clogged EGR valves, blocked DPFs, worn timing chains, and broken turbochargers. Most of them can be avoided with proper maintenance. 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.N47 Reliability: Timing Chain Failures: The most significant issue with the N47 is the timing chain. Many owners have reported premature timing chain failures, which can lead to catastrophic engine damage if not addressed in time. This issue is especially common in engines with higher mileage (over 100,000 miles).If reliability, lower failure risk, and cheaper servicing are priorities, the better choice is the M47 or its later version, the M47N/M47N2. If you care about better performance, quieter operation, and modern technology, you can go for the N47 – but be prepared for possible timing chain failures and high repair costs.
How long do BMW diesels last?
BMWs can reliably hit 200,000 to 300,000 miles with disciplined maintenance, especially models with inline-six or diesel engines like the M54, N52, B58, or M57. Preventive care is the secret weapon. Skipping oil changes, ignoring timing-chain guides (on N20 engines), or postponing gasket fixes will cost far more later. Typically, a vehicle covers about 20,000 km each year, so reaching 100,000 km is quite normal and doesn’t usually mean a drop in performance. On top of that, it is not uncommon to find BMWs past the 100,000 KM range and well into the 200,000 KM range, especially in the older generations like E30s, E36s and E46s.If you’re considering buying one or looking to keep yours on the road for as long as possible, you’ll be happy to know that BMW models are engineered to go the distance. With proper care, many BMWs easily surpass 200,000 miles, and some even push past 300,000. Longevity depends on how well you maintain your vehicle.
