Ordering the correct used automotive part saves time, money and frustration. Even when two cars look the same, parts can differ by engine, production date, equipment level or market. At Partoria we make it easier by letting you search by OEM number and compare detailed photos, but a few simple checks before you order give you the highest chance of a perfect fit.
Here’s a practical checklist to verify compatibility.
1. Match the Full OEM Number
The OEM number is the most reliable way to confirm a part is the same as the one on your car.
-
Compare the complete number, including any letters, spaces or suffixes (for example 5Q0 615 301 AA is not the same as 5Q0 615 301).
-
If the listing shows a superseded number, check whether it officially replaces your original number.
-
Search the OEM number on Partoria and compare the results with the number on your existing part or from your VIN lookup.
If the numbers match exactly, the part is almost always compatible.
2. Confirm Vehicle Details
A matching model name is not enough. Always check:
-
Exact year / production date (mid-year changes are common)
-
Engine code or size
-
Transmission type (manual / automatic / DSG etc.)
-
Left-hand or right-hand drive
-
Body style or trim level if it affects the part (for example headlights, mirrors, interior trim)
-
Any special equipment (adaptive suspension, certain sensors, specific headlight types, etc.)
The more of these details that match the donor vehicle listed in the description, the safer the purchase.
3. Compare Photos Carefully
Photos are one of the biggest advantages when buying used parts. Use them to verify:
-
Overall shape and mounting points
-
Connectors, plugs and wiring (number of pins, shape and colour)
-
Brackets, sensors or additional components that should be included
-
Any visible differences in design
-
Condition of the part (wear, damage, corrosion)
Take clear photos of your original part and compare them side by side with the listing. If something looks different, ask for more photos before ordering.
4. Check What Is Included
Used parts sometimes come with extra pieces or may be missing small components:
-
Does the listing include sensors, brackets, covers or plugs that your car needs?
-
Are any items listed as not included?
-
For electronic parts (ECUs, modules, steering racks), confirm whether coding or programming is required.
Reading the full description and looking at every photo helps avoid surprises.
5. Additional Safety Checks
-
Left vs right: Many parts (mirrors, headlights, control arms, locks) are side-specific. Confirm the correct side.
-
Superseded numbers: Manufacturers sometimes replace an old number with a new one. Both can be valid, but verify the supersession chain if possible.
-
Condition notes: Look for honest descriptions of wear, previous repairs or missing small parts.
-
VIN confirmation: If you are unsure, use your VIN with a dealer or online catalog to double-check the correct OEM number for your specific car.
