Frequently asked questions
Which Bmw X3 engine is the most reliable?
3.0d (M57) (X3 (E83)) — Maint. Sensitive verdict. The 3.0d straight-six (M57) is the engine to have — strong, smooth and one of BMW's most robust diesels, with a front timing chain that doesn't share the N47's failure reputation. It's good for very high mileage. Watch the usual diesel-six items: swirl flaps (delete/inspect), EGR cooler, the occasional turbo or injector at high mileage, and it's thirstier and pricier to service than the 2.0d. A documented M57 is a genuinely durable powertrain.
Which Bmw X3 engines should you avoid?
