Ordering parts for a European vehicle is not always as simple as choosing the year, make and model. Two cars that look identical can use different brakes, suspension components, filters or electrical parts because of their build date, engine, drivetrain or factory option package.
This guide explains how Canadian drivers can verify fitment before ordering. A few careful checks can prevent delays, return shipping and the frustration of discovering that a part does not match after the vehicle has been taken apart.
Start with the complete vehicle configuration
Record the year, make, model and trim, but do not stop there. Fitment can also depend on:
- Engine displacement and engine code
- Front-wheel drive, rear-wheel drive or all-wheel drive
- Automatic, manual or dual-clutch transmission
- Production date or chassis-number range
- Sport, performance or heavy-duty packages
- Brake rotor diameter and caliper type
- Body style, wheelbase and suspension option
This is particularly important for BMW, Mercedes-Benz, Audi, Volkswagen, Porsche, Volvo, MINI, Jaguar and Land Rover vehicles, where a single model year may include several configurations.
Use the VIN to narrow the vehicle
The 17-character Vehicle Identification Number is the best starting point when a catalog asks for precise vehicle information. It identifies the manufacturer and vehicle series and can help distinguish engine, body and production details.
You can usually find the VIN at the lower edge of the windshield on the driver's side, on the driver's door-jamb label, on the registration or on the insurance document. Compare the VIN shown on the vehicle with the documents before relying on it.
A VIN lookup is a selection aid, not a substitute for checking the original component. Vehicles can be modified, and previous repairs may have introduced a different compatible assembly.
Compare the OE number on the original part
An OE number is the identifying number assigned by the vehicle manufacturer. When accessible, inspect the component being replaced and record every readable number. Labels may include a manufacturer number, production code, revision code and supplier number, so photographs are useful.
Search using the complete number first. Spaces, dots and dashes may be displayed differently between catalogs, but the underlying sequence should match. A superseded OE number can legitimately lead to a newer replacement; confirm that the catalog explicitly connects the old number with the new one.
Do not assume that two products are interchangeable because their photos look similar. Connector orientation, mounting points, sensor provisions and dimensions can differ even when the overall shape is nearly identical.
Understand Genuine, OE and aftermarket parts
Genuine parts are packaged under the vehicle manufacturer's brand. OE parts are produced by an original-equipment manufacturer and may be sold under that manufacturer's own brand. Aftermarket parts are alternatives produced for the replacement market.
These terms describe product channels, not automatic fitment. A premium component can still be wrong for a particular chassis or production range. Always prioritize the manufacturer part number, vehicle configuration and catalog notes over a broad category label.
Check the restrictions hidden in catalog notes
Fitment notes often contain the deciding information. Watch for phrases such as “from production date,” “up to chassis number,” “for vehicles with sport suspension,” “excluding performance package,” “with electronic wear sensor” or “for 345 mm rotor.”
Measure when the catalog asks for a dimension. Brake rotor diameter, control-arm length, filter height and connector pin count can be more reliable than appearance. If the old component is available, compare mounting points and electrical connectors before installation.
Verify quantity and side
Confirm whether the listing is for one piece, one axle set or a complete kit. Suspension and steering parts may be sold individually as left or right components. Brake pads are commonly packaged as an axle set, while rotors are often sold individually. The product title alone may not make this clear.
Also check whether mounting hardware, seals, sensors or single-use bolts are included. Ordering the correct main component without the required installation parts can still delay the repair.
Canadian ordering considerations
Canadian buyers should confirm the displayed currency, delivery region, taxes, returns process and expected arrival before completing an order. Keep the packaging and do not install a questionable part until fitment has been confirmed; installed or damaged components may not qualify for return.

A final fitment checklist
- Confirm the complete year, make, model, trim, engine and drivetrain.
- Record the VIN and production date.
- Read the OE number from the original component when possible.
- Review every catalog restriction and option note.
- Compare dimensions, mounting points and connectors.
- Confirm quantity, left/right position and included hardware.
- Verify currency, delivery and return conditions before ordering.
If fitment remains uncertain, collect the VIN, OE number, photographs and vehicle configuration before contacting AM42 Euro Parts. Providing those details at the beginning gives the best chance of identifying the correct component without delay.
