How much does a BMW 2 Series F74 engine replacement cost in the UK?

A reconditioned F74 engine typically costs £1,500–£7,000 supply only, depending on the engine -the B38 three-cylinder sits at £1,500–£3,500, the B48 in the 228 is £2,800–£5,000, and the high-output B48 in the M235 xDrive is £4,000–£7,000. Fitting adds £650–£1,500. Use our calculator for a personalised figure.

Which BMW 2 Series F74 engine is the most reliable?

The B-series engine family (B38, B48, B47) has proven reliability across the BMW range since 2014 -all are chain-driven with accessible front-mounted chains, avoiding the N-series rear-chain issues. The B48 in the 228 is the sweet spot, while the B58 six-cylinder is not offered in the F74. As a new model, long-term F74-specific data is limited, but the engine family is well-proven.

What are the common problems with the BMW 2 Series F74?

As a new model (launched 2025), long-term failure data is limited. Based on the established B-series engine family, the B38 three-cylinder can suffer from engine mount wear. The 48V mild-hybrid system (on 220, 223 xDrive, and 220d models) is relatively new -early issues may include battery degradation or software integration problems. The B47 diesel requires regular motorway runs to prevent DPF clogging.

Is the BMW 2 Series F74 reliable?

The F74 uses BMW's proven modular B-series engine family -the B38, B48, and B47 have been in production since 2014–2015 and have established reliability records. The B48 in the M235 xDrive is a high-output variant but shares its architecture with lower-output B48 engines. As a new model, the F74's specific reliability profile is still emerging, but the engine family is well-regarded.

Which BMW 2 Series F74 engine should I avoid?

We don't say 'avoid' outright -all F74 engines are from the proven B-series family. For buyers who prioritise efficiency, the B38 three-cylinder is the best choice. For performance buyers, the B48 in the M235 xDrive offers 300+ bhp. The B47 diesel is the right choice for high-mileage buyers, though it requires regular motorway driving for DPF health.

How do I know if my F74 engine needs replacing?

As a new model, major failures are unlikely in the early years. Watch for check engine lights, loss of power, misfires, or unusual noises. On B38 models, excessive vibration may indicate mount wear. On 48V MHEV models, reduced assistance or warning lights may indicate system issues. On diesel models, DPF warning lights indicate regeneration issues. Use our diagnostic calculator for a personalised assessment.

Is it worth replacing a BMW 2 Series F74 engine, or should I scrap the car?

As a new model with values above £30,000, a £3,000–£7,000 engine replacement is 10–23% of the car's value -well within our 70% BMW threshold. Replacement is financially viable. Extended warranty cover is strongly recommended, especially for 48V mild-hybrid system components.

How long do BMW 2 Series F74 engines last?

The B-series engine family (B38, B48, B47) has proven capable of 150,000+ miles with proper servicing. The B48 and B47 are chain-driven with accessible front-mounted chains, avoiding the N-series rear-chain issues. The B38 three-cylinder is also robust. As a new model, F74-specific longevity data is not yet available, but the engine family is well-proven across the BMW and Mini ranges.

How do I find my BMW 2 Series F74 engine code?

Listed on the VIN plate and vehicle documentation; the engine code is also stamped on the cylinder block. Common F74 codes include B38A15P (220), B38A15M1 (218), B48A20O2 (228 xDrive), B48A20H/B48R (M235 xDrive), B48A20P (223 xDrive), and B47C20B (218d, 220d).

Overview

BMW 2 Series F74 — Overview

The BMW 2 Series F74 is the second generation of the Gran Coupé four-door saloon, unveiled in October 2024. Built on a carried-over platform with a 2,670 mm wheelbase, the F74 is 20 mm longer (4,546 mm) and 25 mm taller than its predecessor. Manufactured at BMW's Leipzig plant, the F74 adopts BMW's latest design language with slim headlamps, an illuminated kidney grille option, and a '2' emblem on the Hofmeister kink.

Under the bonnet, the F74 exclusively uses BMW's modular B-series engine family — B38 three-cylinder petrol, B48 four-cylinder petrol, and B47 four-cylinder diesel — all paired with a seven-speed dual-clutch transmission. BMW has dropped the 'i' suffix from petrol model names.

Best & Worst Engines

Thin-Data Summary

Thin-Data Fallback mode — one paragraph: The F74's most compelling engine is the B48 in the M235 xDrive — 300–317 bhp from a turbocharged 2.0-litre four-cylinder, making it one of the most powerful four-cylinder engines BMW has ever produced. The B48 in the 228 offers 241 bhp and 400 Nm — the sweet spot of the range for buyers who want performance without the M235's premium. The B38 three-cylinder in the 220 is the most efficient petrol option, with 170 PS and 48V mild-hybrid assistance delivering up to 53.5 mpg. The B47 diesel in the 220d (163 PS) is the choice for high-mileage buyers. All F74 engines are from BMW's proven modular B-series family — the B48 and B38 have established reliability records across the BMW range, though the F74 is too new for long-term failure data to exist.

The F74 rule

As a new model, long-term ownership cost data is limited. The B-series engine family (B38, B48, B47) has proven reliability across the BMW range since 2014 -the B48 and B47 are chain-driven with accessible front-mounted chains, avoiding the N-series rear-chain issues. Early F74 buyers should expect routine maintenance costs comparable to the F40 1 Series and F44 2 Series.

Common Problems

B38

Engine Mount Wear (three-cylinder models)

Affected models:

F74 218, 220 (B38 three-cylinder).

Typical failure mileage:

50,000–80,000 miles.

Root cause:

The three-cylinder B38 engine is inherently less balanced than four- or six-cylinder units. This can lead to premature wear of the engine mounts, resulting in increased vibration and noise in the cabin. This is a well-documented characteristic of three-cylinder B38 engines across the BMW and Mini ranges.

Dealer

Specialist

N/A

Our Recommendation

This is a minor but common issue on three-cylinder B38 models -a £200–£400 mount replacement restores the car's refinement and is one of the cheapest fixes on the range. The B38 engine itself is robust and chain-driven.

Compare B38 engine mount replacement quotes for your F74

48V

Mild-Hybrid System Integration (MHEV models)

Affected models:

F74 220, 223 xDrive, 220d (48V mild-hybrid equipped models).

Typical failure mileage:

Unknown -new technology.

Root cause:

The 48V mild-hybrid system (integrated starter-generator, 48V battery) is relatively new across the BMW range. Early issues may include battery degradation, software integration problems, or starter-generator failures. The system provides up to 20 PS of electric assistance.

Our Recommendation

As a new system, long-term reliability data is limited. Ensure the 48V system is covered under warranty and have it inspected at major services. The mild-hybrid system provides efficiency benefits but adds complexity.

Compare F74 48V mild-hybrid system checks

B47

Diesel DPF Clogging (urban use)

Affected models:

F74 218d, 220d (B47 diesel).

Typical failure mileage:

60,000–100,000 miles (urban driving).

Root cause:

Like all modern diesel engines, the B47's diesel particulate filter (DPF) can clog with soot if the car is predominantly used for short urban journeys where the DPF regeneration cycle cannot complete. The B47 is otherwise a robust and proven engine.

Our Recommendation

If you're buying a diesel F74 for urban use, ensure regular motorway runs to allow passive DPF regeneration. A £300–£600 DPF clean is far cheaper than the £1,000–£2,000 replacement that follows if ignored. The B47 is otherwise a dependable engine.
