A useful VAG electronic parts catalog should help a workshop move from vehicle identification to the correct catalog group and part reference without turning every parts query into a long manual search. This guide explains the main VAG EPC access styles and when a desktop or web solution makes more sense.
What is a VAG EPC?
EPC means Electronic Parts Catalog. For supported Volkswagen Group vehicles, an EPC organizes parts by brand, model, production information, assemblies and catalog groups. Depending on the system and coverage, VIN information can help narrow the vehicle configuration.
An EPC is a research tool, not a guarantee that every displayed part fits every market version. Before ordering, verify the VIN, production date, PR/equipment information, supersessions and local part availability.
Desktop VAG EPC: EPCWire
EPCWire VAG EPC & Wiring Online System is a Windows desktop application combining VAG ETKA electronic parts information and ELSA wiring information. It is suitable for technicians who want both parts and electrical research inside one dedicated application.
- One-year access
- Up to four VIN searches per day in total
- ETKA electronic parts information
- ELSA online wiring information
- Windows 10 and Windows 11 desktop application
- Use on up to two physical PCs
- No virtual-machine or older-Windows support
- Application email required for activation
EPCWire is not a browser service. Before adding it to the cart, the customer must enter the exact email address that will be used in the application. 1XOBD creates the activation for that address, which is saved with the order. The same activation may be used on two physical Windows 10/11 PCs, while the subscription retains one shared daily limit of four VIN searches.
Browser-based ETKA and ELSA
If you do not want to install a Windows desktop application, choose the separate ETKA and ELSA WEB product. A web workflow is convenient when the user needs browser access, while EPCWire is intended for a dedicated workshop computer.
How to choose the best VAG EPC system
- Choose by platform: dedicated Windows application or browser.
- Check VIN limits: estimate the number of vehicles researched each day.
- Confirm brand coverage: verify the Volkswagen Group brands and markets you service.
- Consider wiring needs: a workshop may benefit from parts and wiring in the same tool.
- Use the correct activation email: enter the address that will be registered in EPCWire, not merely a contact address.
EPCWire or ETKA/ELSA WEB?
Choose EPCWire for a Windows desktop workflow with ETKA and ELSA information in one application. Choose ETKA and ELSA WEB when browser access is the priority. The two products are separate; purchasing EPCWire does not include the web service.
