Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
The engine code is essential for ordering parts, diagnosing issues, and verifying compatibility. It is not the same as the VIN or chassis number. This guide shows exactly where to find it - by model and engine type - using official BMW Group and DVLA sources
A unique identifier stamped on the engine block or cover used for parts and service.
The vehicle identification number that holds encoded vehicle and engine information.
The chassis or frame number used for registration and legal identification.
Locate the engine code on a white label attached to the front timing cover, near the camshaft housing. It reads 'N14B16A' for the 1.6L TwinPower Turbo variant.
The engine code is located on a white label attached to the camshaft cover, near the oil filler cap. It reads 'B38A15A' or 'B38B15A' for the 1.5L TwinPower Turbo variant.
Open the bonnet and look at the front left of the engine (driver side). The code is on a white label near the timing cover. Confirm 'B48A20A' for the 2.0L TwinPower Turbo petrol variant.
The electric motor code is located on a label near the motor housing. It reads '5HE01' for the 135 kW permanent magnet synchronous motor used in the Cooper SE.
Engine code locations per BMW Group ELSA Document A15001 – Vehicle Identification. V5C field definitions from DVLA Guide to Vehicle Registration. VIN structure compliant with EU Regulation (EC) No 715/2007, Article 7. Note: MINI uses BMW Group VIN structure; engine code positions reference BMW engine families.
A technical breakdown of MINI's core engine systems including TwinPower Turbo, Valvetronic, timing architectures and BMW Group modular design with documented reliability impacts. All data sourced from BMW Group Technical Documentation, BMW Group ELSA and EU Regulation (EC) No 715/2007
MINI's TwinPower Turbo system combines turbocharging, direct fuel injection, and Valvetronic for optimal power-to-efficiency ratio across the N-series and B-series engine families.
High-pressure turbocharging with intercooling, direct injection at 200 bar, and Valvetronic variable valve lift work together to deliver strong low-end torque with reduced fuel consumption and emissions.
N14B16A (2007)
First MINI turbo; timing chain issues
N18B16A (2011)
Revised tensioner, improved reliability
B38A15A (2014)
Modular 3-cylinder, improved efficiency
B48A20A (2017)
Modular 4-cylinder, JCW performance
Carbon buildup on intake valves
Direct injection only; requires walnut blasting service
HPFP wear (N14)
High-pressure fuel pump failure symptoms: lean misfire, P0171
Timing chain tensioner (N14/N18)
Early tensioner design; updated part via TSB 18-4321
Water pump leaks
Plastic impeller degradation; common at 80k+ miles

MINI vehicles are assembled at three primary facilities within the BMW Group network, with engines sourced from BMW Group engine plants.
MINI produces approximately 280,000–320,000 vehicles per year. Note the steady decline in Diesel production due to Euro 6d and WLTP regulations, while Electric integration rises.
Note: Diesel production has declined steadily due to Euro 6d and WLTP regulations (Regulation (EC) No 715/2007). Electric vehicle integration rising.
Strategic integration within BMW Group since 2000. B-series/N-series engine families are shared across MINI, BMW, and other Group brands, utilising common engineering and production workflows.

The most common questions about engine codes, what they mean, how to find them and how this database works
Confirm the full engine designation using vehicle-specific manufacturer records and the engine marking. An engine serial number, a registration record and a marketed power badge are not automatically the same identifier. Match the VIN/build data and the installed engine before selecting parts or a replacement.
No. A factory-application reference and a replacement-interchange decision are different. Match the full engine designation, vehicle build data, emissions equipment, controls and relevant supplier/OEM information.
No. Records have different review states. Read the correction notice, source scope and application limits on the individual record. Missing technical fields must not be inferred from similar engine codes.
