The 38-Pin OBD2 Adapter Benz is a diagnostic cable used to connect modern 16-pin OBD2 diagnostic scanners to older Mercedes vehicles equipped with a 38-pin round diagnostic port. This adapter converts the vehicle’s proprietary 38-pin connector into the standard 16-pin OBD2 interface, allowing technicians to use common scan tools for diagnostics. Many Mercedes-Benz models produced before the full adoption of OBD2 used this 38-pin diagnostic port located in the engine bay, rather than the standard dashboard OBD2 socket. The adapter bridges the communication gap so diagnostic devices can read vehicle data, retrieve fault codes, and monitor live parameters. Key Features 38-Pin to 16-Pin Conversion – Allows modern OBD2 scanners to connect to older Mercedes vehicles. Plug-and-Play Design – No software installation required. Durable Diagnostic Cable – Flexible cable with strong connectors for workshop use. Access Multiple Vehicle Systems – Enables diagnostics of engine, transmission, ABS, and other modules depending on the scan tool used. Vehicle Compatibility Typically used with Mercedes-Benz vehicles manufactured roughly between 1990 and early 2000s, including models such as: C-Class W202 (1993–2000) E-Class W124 / W210 S-Class W140 SL-Class R129 Early Sprinter and Vito models Technical Specifications Vehicle Connector: Mercedes 38-pin (male) Scanner Connector: OBD2 16-pin (female) Cable Length: approx. 25–40 cm Material: PVC insulated cable with molded connectors Package Includes 1 × 38-Pin Mercedes to 16-Pin OBD2 Adapter Cable
