A re-programming with Bosch KTS series is currently not possible because of the change in the "Euro 5 Portals for the VW group," and introduction of ODIS in their authorized workshops.

Information on Volkswagen

Volkswagen provides access to erWin under the link erWin.Volkswagen.com. erWin is the Electronic Repair and Workshop Information from Volkswagen AG, both for independent workshops, car fleets and all other companies that repair and service Volkswagen vehicles on a professional basis, as well as for all private persons who wish to repair their Volkswagen vehicle themselves.


The KTS 520 / KTS 550 and KTS 650 cannot be used with vehicles of the VAG-Group (VW, Audi etc.).

The vehicle diagnostics allow you to select between a complete diagnostic system (VAS diagnostic system), which has the advantage that diagnostics can be carried out on all Volkswagen brand vehicles, or the EU-5-VAS diagnostics software via an SAE J2534-compatible interface (diagnostics interface), which allows you to perform offboard diagnostics on vehicles with Euro-5 model approval.


For these applications, users have to register in advance and then log in.
