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 MG Motor 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 label attached to the camshaft cover or timing belt cover. It is typically a white or silver sticker showing '15S4C' for the 1.5L VTi-Tech engine.

The engine code is located on a label near the turbocharger or on the engine block. Look for '15C4E' designation for the 1.5L turbocharged engine producing 169 PS.

Open the bonnet and look at the top of the engine. The code is on a label attached to the camshaft cover or valve cover. Confirm '15S4C' for the 1.5L naturally aspirated engine.

The engine code is cast into the engine block or on a label near the inlet manifold. Look for '18K4F' for the 1.8L turbocharged petrol engine.
Engine code locations per MG Motor Service Documentation. V5C field definitions from DVLA Guide to Vehicle Registration. VIN structure compliant with EU Regulation (EC) No 715/2007, Article 7.
A technical breakdown of MG's core engine systems including VTi-Tech, SGE turbocharged engines, timing architectures and modern design with documented reliability impacts. All data sourced from MG Motor Technical Documentation, SAIC Motor Engineering Reports and EU Regulation (EC) No 715/2007
MG's VTi-Tech (Variable Timing Intelligence) is a naturally aspirated engine family featuring DOHC configuration with variable valve timing for improved efficiency and performance across the rev range.
The VTi-Tech system uses variable camshaft timing on the intake side to optimize valve timing based on engine speed and load, improving low-end torque and high-RPM power while maintaining fuel efficiency.

13S4C (1.3L)
Entry-level variant
15S4C (1.5L)
Main production engine
15S4C updated (2018)
Improved emissions, Euro 6
Timing belt maintenance
Regular replacement required at 60,000 miles
EGR valve clogging
Common in urban driving conditions
Oil consumption
Some units report increased consumption after 80,000 miles

Authoritative data on MG's global engine production, plant operations, and strategic partnerships. All figures sourced from SAIC Motor Annual Reports, Sustainability Reports, and EU industrial compliance records.
MG engines are manufactured at SAIC Motor facilities globally, with key production hubs in China and historical UK operations.



MG produces approximately 350,000+ engines per year. Note the complete phase-out of diesel by 2023 and rapid growth in hybrid and electric powertrains.
Note: Diesel production was discontinued in 2016 due to Euro 6d compliance costs. MG has rapidly expanded EV and hybrid production to meet EU 2035 ICE phase-out targets.
SAIC Motor collaborates with General Motors and other partners for technology sharing and joint development.
SGE (Small Gasoline Engine) co-developed with GM
Manufactured at SAIC facilities for MG and GM brands
SAIC Motor Strategic Partnerships – GM Collaboration
Shift in production reflects EU emissions policy and MG's electrification strategy.
This aligns with Commission Regulation (EU) 2017/1151 (WLTP/RDE) and EU 2035 ICE phase-out roadmap.

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.
