erWin

 

One access. Eight brands. All in one place. The new erWin.

Central Volkswagen Group online portal for repair, maintenance and diagnostic information.

What is erWin about?

erWin is the central Volkswagen Group online portal that provides independent workshops and other professional operators with paid access to OEM repair, maintenance and diagnostic information for eight brands of the Volkswagen Group. The portal is operated by Volkswagen Group Info Services AG and focuses on business customers that need OEM-compliant information for their daily work on Volkswagen Group vehicles.

On the front end, erWin offers a modern online shop where workshops register with a business account, maintain their company profile and users centrally and purchase time-based licences for the required brands in their market. Once a licence is active, users move from the shop environment into the connected professional back-end systems of the respective brands – for example to the repair and maintenance information frontends and diagnostic applications – where they carry out their technical work.

The new erWin portal consolidates the previous brand-specific solutions into one central access point, reduces complexity for brands and workshops, and helps to fulfil regulatory obligations for providing Repair and Maintenance Information (RMI) to independent operators.

One access. Eight brands. All in one place.

The new erWin.

Features

  • Central online portal and licence shop for Volkswagen Group repair, maintenance and diagnostic information
  • One Business ID account with central company and user management for independent workshops, workshop groups and other professional operators 
  • Time-based licences (hour, day, week, month, year) for brand-specific RMI and diagnostic access (Lamborghini diagnostic information only)
  • Single access point leading into the connected professional systems (e.g. RMI frontends, diagnostic tools) after purchase
  • Brand and market selection according to the workshop’s business needs and regulatory scope
  • Consolidated license overview and administration for all active products and brands
  • Licence pooling within one company account: Licences are purchased for the company (One Business ID) and valid company-wide. Multiple licences can be used simultaneously by multiple employees (one licence per user).

Note: Diagnostic licences for ODIS require specific prerequisites (see below).

Key benefits

  • One access
    One central, official portal instead of multiple brand- or market-specific erWin pages. Workshops have a clear login and licence flow for all supported Volkswagen Group brands and all their employees in one place.
  • Eight brands
    Access to official repair, maintenance and diagnostic information of Volkswagen Passenger Cars, Volkswagen Commercial Vehicles, Audi, SEAT, Cupra, Škoda and Bentley, as well as the diagnostic information of Lamborghini, aligned with RMI regulation in the supported markets.
  • All in one place
    Consolidated licence and user management in one environment, reducing administrative effort and making it easier to keep an overview across brands, licences and users.
  • Plus: Future readiness
    A modern, centralised setup with clear governance that can be further developed. For example with improved user journeys, additional functions and more digital support along the end-to-end workshop workflow.

Usage Process

erWin does not provide a data feed via API. Instead, it grants licensed users access to OEM-operated systems that contain the official repair, maintenance and diagnostic information for Volkswagen Group vehicles (Lamborghini diagnostic information only).

Typical usage process for an independent workshop:

Registration and account setup

 
  • Workshop registers a One Business ID account
  • Company profile and users are created and managed centrally in one account
Read our onboarding guide

Licence purchase in the erWin webshop

  • Workshop selects the relevant brand(s) and licence type (e.g. hourly, daily, or longer periods)
  • Licence is purchased in the shop environment. The license term begins immediately after purchase.

Access to the connected professional systems

  • From the erWin portal, users are guided into the appropriate brand systems (e.g. RMI frontends, diagnostic applications)
  • Technical work is carried out directly in these systems

Important

For diagnostic licences using ODIS, additional prerequisites apply:

  • The workshops working context / Global User ID must be added to their profile (stored permanently once added). Existing working context numbers from the old erWin can be reused. Only if they don't have a working context yet, a new application is required.
  • The software ODIS can be downloaded and installed once the working context is available – i.e. before purchase.
  • The licence period starts immediately after purchase.

Available Data

After purchasing the appropriate licence in the erWin webshop, users can access the OEM-operated systems of the respective brands. Within these systems, the following types of information are available (depending on brand, market and licence):

• Repair & Maintenance Information frontends – access to official workshop manuals, repair guides, curcuit diagrams and component locations, chassis repair, maintenance tables, working positions, emissions test and service information as provided by the brands’ systems.

• Diagnostic applications – access to diagnostic environments for independent workshops where available within the regulated scope.

• Vehicle identification context – use of OEM systems such as GVF/Carport for correct vehicle identification in the connected systems (e.g. via VIN), ensuring that the right information is applied to the right vehicle.

The core element of this information is the work steps required for service, maintenance and repair, including the estimated effort of working hours (without hourly rates / costs).

The exact content and user experience inside these systems is defined and operated by the respective brands and Group IT environments. erWin provides the standardized access and licensing framework that connects independent workshops to these resources.
