This directory links to engine-reference records and their correction notes. It is not a complete or uniformly verified catalogue. Confirm the exact engine and vehicle before relying on a specification or application.
Records undergoing identity review are clearly marked. Only records with an evidenced manufacturer/vehicle allocation belong in the factory-application list.

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.
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. Use the applicable manufacturer record to locate the engine marking. This directory does not assert one universal VIN decoding position or stamp location. A V5C engine-number field is not, by itself, proof of an exact engine-type designation.
Keep these families separate: modern four-cylinder Ingenium diesel; older 2.2-litre 224DT diesel; 3.0-litre 306DT V6 diesel; Ford-related GTDi petrol; AJ126 supercharged V6; AJ133 V8; and later Ingenium six-cylinder powertrains. The 204DTD record must not be dated to the 1980s. Do not group 306DT into the four-cylinder Ingenium chain discussion. Similar-looking 204PT and PT204 strings require an evidenced alias mapping. Read the individual record’s source and application scope. A technology or service requirement must not be applied to an entire brand because one engine uses it.
Production volumes, plant allocations and partnership applications require a dated manufacturer source. The previous unsourced figures and cross-brand fitment claims have been withdrawn from this hub. A manufacturing relationship does not establish engine interchangeability.
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.
