A used part can cost a fraction of a new one, and for many repairs it’s a smart choice. Before you pay, check seven things: the part number, the exact fitment, the condition, the donor car, the warranty, whether the part needs coding, and how it will be delivered. Getting these right saves you from a part that looks right but doesn’t fit or won’t work.
When used parts make sense, and when they don’t
Used original-equipment parts are a good fit for body panels, lights, interior trim, mirrors, electrical modules, engines, gearboxes and many mechanical parts. These parts usually last well beyond the life of the car they came from.
For wear items like brake pads, discs, filters, belts and wiper blades, new is usually the better buy.
1. Match the part number
The most reliable check is the part number on your old part. BMW numbers are usually 11 digits, Audi and VW use codes like 8K0 807 113 F, and Mercedes-Benz numbers start with A. Our guide How to Find the Right Part Number for Your European Car shows where to look.
2. Confirm the exact fitment
If you can’t match a number, check the details that change parts within a model:
- Build year and facelift: many European models change parts mid-production
- Engine and gearbox code: essential for engines, gearboxes and engine parts
- Left or right side: as you sit in the driver’s seat
- Options: halogen or xenon lights, parking sensors, heated mirrors, premium audio
If in doubt, give the seller your VIN or rego and ask them to check.
3. Look closely at the condition
Ask for clear photos of the actual part, not a stock image. Check mounting tabs, clips and brackets, which are easily broken. Check electrical connectors for corrosion or damaged pins, and lenses and panels for cracks, chips or scratches. Ask what grade the part is and what any marks are.
4. Know where it came from
A good dismantler can tell you the donor vehicle: its year, model, engine and, where recorded, the kilometres. That helps you confirm fitment and judge wear, especially for engines and gearboxes.
5. Check the warranty
Find out how long the warranty lasts and what it covers. Most used-part warranties cover the part itself, not the labour to fit or remove it. At European Specialist Parts, used parts come with a 90-day parts warranty from the invoice date, and extended warranty is available on request.
6. Ask whether it needs coding
Many modern European cars use electronic modules that must be coded or programmed to your car. These include engine computers, body control modules, key and immobiliser modules, instrument clusters and some lights. A used module may work only after a workshop with the right equipment codes it. Factor that cost in, and check with your mechanic before you buy.
7. Plan delivery and returns
Small parts can travel by post. Engines, gearboxes, doors and bumpers need freight and good packaging. Confirm the delivery cost, how the part will be packed, and what happens if it arrives damaged or doesn’t match the listing. You can also collect from our yard in Pakenham to save on freight.
