The BMW 1 Series is a compact executive hatchback that brings the hallmark BMW driving experience into a more urban-friendly package. First launched in 2004 (E87), the 1 Series became BMW’s entry-level model, popular among younger drivers and city commuters. Over the years, it evolved through the F20 generation (2011–2019) and into the current F40 lineup introduced in 2019, offering more interior space, improved tech, and front-wheel drive variants. With sporty trims like the M135i and fuel-efficient diesels like the 116d, the 1 Series combines performance and practicality in a sleek design – making it one of the UK’s best-selling premium hatchbacks.
Whether you need a replacement due to timing chain issues, overheating, or general wear and tear, Engine Finders makes it easy to locate the right 1 Series engine, fast.
BMW’s 1 Series engines range from compact 3-cylinder petrol to performance-tuned turbocharged 4-cylinders. Whether you're driving an early E87 or a newer F40 M Sport, we can help you find the exact engine code match.

When your engine fails, BMW 1 Series engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here’s how experts ensure optimal results.
Specialists first scan your BMW engine’s computer for faults, then strip the unit completely. Every part is logged, measured, and inspected for wear or damage.
All parts (blocks, heads, manifolds) are cleaned in ultrasonic baths. Critical parts like cylinder heads are pressure- or dye-tested to ensure no cracks or failures remain.
Crankshafts, camshafts, and engine blocks are machined to original tolerances. Cylinders are bored, and heads are surfaced so the rebuilt engine meets factory specs.
All internal parts (pistons, rings, bearings, seals, timing chains/belts, etc.) are replaced with new OEM (or upgraded) components. High-wear parts like oil pumps and water pumps are typically new as well.
The engine is reassembled in clean-room conditions. Once built, it’s run on a test bench to check oil pressure, temperature regulation, and performance. Final tuning and calibration ensure it runs like a genuine BMW engine.
Each rebuilt engine is delivered complete and ready to fit. Suppliers provide reports on all work done, plus the engine’s warranty – so your BMW 1 Series feels “as good as new” when the replacement engine is fitted.
