OBD: MAHLE to provide access to Mercedes-Benz vehicles

Published:  27 October, 2020

MAHLE and Daimler AG have agreed terms on access to the encoded OBD diagnostic ports of Mercedes-Benz vehicles.

As a result, users of the MAHLE TechPRO or BRAIN BEE CONNEX diagnostic tools will be able to retrieve vehicle data via the Cyber Security feature. Security certificates are obtained by accessing the Daimler portal with an annual subscription from MAHLE or BRAIN BEE.

As a special promotion, MAHLE is offering free access to active license holders until the end of the year.

In August, it was confirmed by the Department for Transport (DfT) that the OBD port will remain open by law for repair and maintenance information (RMI), and that this information will be made available in an electronically processable format, ending years of uncertainty on the subject.

Type Approval Regulation (EU) 2018/858 keeps the OBD port open in the EU, but the Brexit made this a more complicated subject in the UK.

The issue of how security-related repair and maintenance information (SERMI) would be handled remains a key question however. With this in mind, Daimler AG will put in a security gateway to prevent third-party access to security-relevant functions of its vehicles, This will mean that data can only be read via the OBD interface, but not written or deleted if original testers from Daimler AG are not used or if a certificate is not exchanged between the tool and Daimler.

Commenting on the arrangement, Joachim Schneeweiss, Head of Sales EMEA at MAHLE Aftermarket Service Solutions, said: “With this agreement, we’re giving independent workshops much greater flexibility when it comes to servicing Mercedes-Benz vehicles.”
