Frequently asked questions
Which Bmw 2 Series engine is the most reliable?
218i / 220i / 230i (B38 / B48 turbo) — Maint. Sensitive verdict. The modular turbo petrols — the 1.5 three-cylinder B38 (218i) and the 2.0 four-cylinder B48 (220i/230i, shared across the 1/3-Series, X1 and Mini) — are a genuine step up in robustness from the older N-series: timing chains run at the front (not the failure-prone rear of the N47), and they're smooth and strong. Cautions are direct-injection intake carbon over time, occasional VANOS/PCV and turbo coolant attention, and oil/cooling discipline. The B48 in particular is a well-regarded modern engine; a serviced car is dependable. The F45 Active Tourer is BMW's first transverse front-driver — different platform, same good engines.
