What is the Vauxhall parts catalog called?
“Vauxhall EPC” is a useful search phrase, but it is not a precise name for one uninterrupted factory dataset. Stellantis’s own Service Box terms distinguish the spare-parts catalog for new Opel/Vauxhall vehicles from Opel/Vauxhall Legacy information. The split follows the move from General Motors to PSA architecture, and it matters more than the date on the number plate.
The Vauxhall and Opel badges usually lead to the same vehicle family. UK right-hand-drive parts can still differ: steering and pedal hardware, dashboard sections, wiper mechanisms and some lamps deserve a VIN-level check.
How to tell which parts system to use
Look up the VIN before choosing a catalog era. A Corsa E and a Corsa F share the name but belong to different engineering families. The Mokka name also spans a substantial platform change. Registration year is not a safe shortcut near a model changeover.
Once the record is open, confirm model series, engine, transmission and drive side. Find the assembly group, read its callout and applicability note, then check the service reference and any replacement. If a supplier offers a Peugeot number for a newer Vauxhall, confirm the cross-fit in the vehicle record rather than rejecting or accepting it because of the badge.
A familiar van with several possible builds
Vivaro is a particularly good reason to start with the VIN. A commercial vehicle can change parts with wheelbase, roof, payload and engine. Those differences may not show in a photograph of a filter housing or suspension arm. The catalog record gives the build conditions that a broad “Vivaro parts” search cannot.
On body and cabin parts, inspect drive side and equipment as carefully as the engine. A correct-looking panel for a left-hand-drive Opel can still be wrong for a UK Vauxhall.
Using the result at the counter
Copy the full number and tell the supplier the vehicle model and VIN, especially if the number has been superseded. Compare the part on the bench before fitting it.

Common Vauxhall nameplates
These nameplates help you find the right vehicle family. Confirm the exact model, market and production period against the active catalog before quoting a part:
| Model | Production years |
|---|---|
| Vauxhall Corsa | — |
| Vauxhall Astra | — |
| Vauxhall Mokka | — |
| Vauxhall Vivaro | — |
A Vauxhall parts-desk check: Corsa E or Corsa F?
A request for Corsa parts needs the generation before the catalog scope. Stellantis distinguishes newer Opel/Vauxhall information from Legacy information, and UK driving-side details still matter.
Identify the generation from the vehicle
Resolve the VIN and verify the returned series, engine and transmission. A registration year near a model change is an unreliable substitute.
Confirm the information scope
Check whether the application belongs to the newer Service Box scope or Legacy information. Do not assume a Corsa name establishes one uninterrupted parts dataset.
Read right-hand-drive conditions
For steering, pedals, dashboard or wipers, check driving side and equipment. An Opel reference from another market needs application confirmation for the UK vehicle.
Follow the selected line to the current reference
Match the diagram position and conditions, then copy the full number, quantity and any replacement. A Peugeot-style number can be a candidate for a newer vehicle, but the VIN must confirm it.
This is a selection checklist, not a recorded Corsa parts match. If the generation or catalog scope is unresolved, clarify it before taking the order.
Frequently asked questions
Is Vauxhall EPC the same as Opel EPC?
Vauxhall and Opel often describe the same vehicle family under different badges. The correct parts scope still depends on generation, and right-hand-drive Vauxhall parts can differ from left-hand-drive Opel parts.
Does Service Box cover every Vauxhall?
Stellantis separates newer PSA-derived Opel/Vauxhall vehicles from Opel/Vauxhall Legacy information. Check the specific VIN and generation before assuming coverage.
Why does a newer Vauxhall sometimes have a Peugeot-style number?
Newer PSA-derived vehicles can share platforms and components with Peugeot and Citroën. A shared number may be valid, but verify it against the Vauxhall VIN.
What should I check on a UK Vauxhall?
Confirm the VIN, model generation, engine, drive side, diagram callout and any supersession. Steering, pedals, dashboard and wiper parts deserve special attention.
