Fitment Help

How to know it will fit

Before you buy, there are three ways to confirm a part is right for your vehicle:

1. Your UK registration plate — the fastest way. Send us your reg and the part you are looking at, and we will cross-check against the manufacturer’s data.

2. Your VIN (Vehicle Identification Number) — the most reliable. Your VIN encodes the exact build of your car, including engine code, trim and any mid-cycle variations. You will find it on the V5C logbook, stamped on the chassis (often visible through the windscreen), or on a sticker in the driver’s door jamb.

3. The OE number on the original part — the gold standard. If you can read the part number off the old part, we can match it directly. See below for what an OE number is and where to find it.

If you have got any of these three, we can confirm fitment for you in under an hour during opening hours.

What is an OE number?

An OE (Original Equipment) number is the manufacturer’s unique reference for a specific part. It is usually printed or stamped directly on the part itself — on a label, etched into the casing, or moulded into the plastic.

For example: a BMW oxygen sensor might have 0258006206 printed on it. That is the Bosch part number, which can be cross-referenced to fitments across dozens of BMW, MINI and Rolls-Royce models.

Why OE numbers matter: vehicles within the same model range often use different parts depending on engine, year, trim, or even the production date. The OE number on your old part is the most reliable way to find an exact match — better than reg, better than VIN.

If you can find and photograph the OE number on your old part, send it to us and we will cross-reference it.

Common fitment mistakes (and how to avoid them)

Same model, different engine — A “Focus 1.6” and a “Focus 1.6 TDCi” can use entirely different sensors, pumps and actuators. Always check engine code, not just model.

Pre-facelift vs post-facelift — Many cars get a mid-cycle update that changes electronics, body panels and sensor locations. A 2017 model may use parts from either the pre- or post-facelift run depending on the build month.

LHD vs RHD — Right-hand-drive UK cars sometimes use different parts (notably wiper linkages, headlight units and some sensors) than left-hand-drive equivalents. Always confirm the part is for a UK-spec vehicle.

Year ranges are guides, not guarantees — A “2014–2018” fitment range usually means “most builds in those years”, not “every build”. Mid-cycle changes can shift fitments by a few months.

Aftermarket vs OE replacements — An aftermarket part may fit physically but use slightly different electrical specs. For sensors and electronic parts, OE-grade matching is the safe choice.

Category-specific fitment notes

Ride Height & Level Sensors — These vary by suspension type (air vs steel), trim level (M Sport vs standard) and sometimes by axle. Match by OE number wherever possible.

Oxygen & Lambda Sensors — Pre-cat vs post-cat sensors are different parts. Most modern cars have two or four. Check the connector type (4-wire vs 5-wire is common) and cable length.

Fuel Pressure Sensors — High-pressure (rail) sensors and low-pressure sensors are not interchangeable. Diesel and petrol variants differ. Always match by OE number.

Door Lock Actuators — Driver vs passenger, front vs rear, and central locking versus keyless variants are all distinct. Year and trim matter.

Airbag & Clock Spring — Highly model-specific and often updated mid-cycle. Always match by OE number; an incorrect clock spring can disable steering wheel controls and airbag deployment.

What if it does not fit?

If a part does not fit, get in touch and we will sort it. Our refund policy covers fitment returns: as long as the part is unused, in original packaging and reported within 30 days, you can return it for a refund or exchange.

Despite using the latest manufacturer fitment data, we cannot always guarantee 100% accuracy across every build variation — that is the nature of car parts. But we are a small UK team and we will help you get to the right part.

We would rather check fitment with you than send the wrong part. Reach us however suits you:
