Universal · OBD cables
Main connection cable used between the Mercedes-Benz XENTRY Diagnosis VCI (C6) and the vehicle's 16-pin OBD2 socket; original Bosch and compatible cable options are clearly separated on the same page.
The exact plan and total amount will be shown again at the payment step.
First, verify the 26-pin D-sub connector on the device side of your cable and the 16-pin OBD2 end on the vehicle side; then select the Original Bosch or Compatible Cable option.
Product information
This page offers two different product options. The Original Bosch variant is presented with official Mercedes-Benz product identification and visuals. The compatible variant is an equivalent cable for the same connection task; it does not provide guarantees of Bosch or Mercedes-Benz manufacturing, part number, or logo. The name and price of the selected variant appear separately in the cart line item.
Physical Connection Coverage
Connecting the cable, adapter, or communication module to the vehicle does not prove that the vehicle is supported by the software. The physical connector, pin layout, main device, and vehicle software must be compatible simultaneously.
Product details
The original Bosch option is the 16-pin OBD connection cable listed by Mercedes-Benz for the XENTRY Diagnosis VCI. In the official XENTRY Shop record, the product number is given as 6511251799. For the compatible variant, no claim of Mercedes-Benz or Bosch manufacturing, official part number, logo, or authorized service part is provided.
The customer sees the variant name, description, and price separately before adding to the cart.
Product details
The Mercedes-Benz XENTRY Shop defines product number 6511251799 as a 16-pin OBD adapter cable that establishes a connection between the XENTRY Diagnosis VCI and the vehicle. The same record lists compatibility with XENTRY Diagnosis Kit 3, Kit 4, Kit 4 Scope, Kit 5, Kit 5 Scope, and XENTRY Diagnosis VCI.
This compatibility does not mean the cable alone performs diagnostics: VCI hardware, the correct vehicle, a legal XENTRY environment, and the necessary user authorization are also required. The Bosch 1699200142 reference is used for the XENTRY VCI C6 main OBD cable by professional spare parts dealers; the physical label and supply record are the basis for the order.
Product details
The six transparent product photos in the gallery are official Original Bosch cable images from Mercedes-Benz. The Mercedes-Benz marking, molded gray connector housing, label, and pin details in these photos represent the Original Bosch option only.
The Compatible Cable option is a comparable product with the same 16-pin OBD2 and 26-pin VCI connection layout; the housing color, logo, label, mold mark, and inscriptions on the cable may vary depending on the production batch.
Customers purchasing the compatible option should not expect the brand and part number markings shown in the gallery as part of the delivery scope.
Product details
Since the name C6 can be used for different hardware in the market, do not order based on the product name alone. The 26-pin D-sub input with two locking screws on the XENTRY Diagnosis VCI side and the 16-pin OBD2 connector on the vehicle side must be present.
The round multi-pin device end seen on the main cables for SD Connect C4 and C5 is not the same as this product. Compare the number of pins, screw spacing, key structure, and the input on the VCI with the close-up views in the gallery. Do not force the connector if it does not fit perfectly or the screws do not align.
Product details
The main OBD cable carries the physical data and power connection between the diagnostic socket in the vehicle and the XENTRY Diagnosis VCI. The cable does not add a protocol not present in the VCI hardware; it does not provide software license, StartKey, online coding authorization, or vehicle coverage.
Communication capabilities such as DoIP cannot be guaranteed by looking at the cable head alone; VCI hardware, vehicle architecture, XENTRY version, and authorization must be verified separately. Vehicle power supply, connection stability, and manufacturer procedures must also be maintained during programming or coding.
Product details
When opening the order package, check the variant name on the cart and invoice line. For the Original Bosch option, examine the product ID, supply record, connector mold, and label information together; the gray color or Mercedes star alone is not proof of originality.
For the compatible option, verify that the order is for a comparable product and that the two connectors are intact and of the correct type. If bent or retracted pins, a cracked housing, a loose cable gland, or damaged screws are found on either variant, open a support ticket before using it on the vehicle.
Product details
Before using the Mercedes XENTRY VCI C6 16-Pin OBD2 model, compare the connectors on the main unit and the vehicle side. Match the main unit model, the two connectors, and the pin layout with the connection cable label. If the connection cable has bent pins, a cracked casing, or a loose connector, do not establish a service connection.
After the connection cable is inserted without force, perform a short read test. Record the communication result, specifying the device and vehicle socket used with the connection cable.
Product details
When communication cannot be established with the Mercedes XENTRY VCI C6 16-Pin OBD2 model, first verify that the vehicle socket has power and that the main unit is operating. Re-examine the pins on the connection cable, the cable casing, and the connector orientation. Test the connection cable briefly on a known compatible device or vehicle connection.
If the connection cable cannot communicate despite the correct main unit model, vehicle socket, and connector structure, add a screenshot of the error screen and photos of the two connectors to the service record. At the end of the task, disconnect the connection cable by holding the connector housing and store it without coiling at a sharp angle.
Product details
The choice between the Mercedes XENTRY VCI C6 16-Pin OBD2 model and the Autocom CDP+ Compatible OBD2 Main Cable, Delphi DS150E Compatible OBD2 Main Cable, Ford VCM II Compatible OBD2 Main Cable, and Opel / GM MDI Compatible OBD2 Main Cable is made based on differences in supported functions, connections, and packages.
In the comparison of the Mercedes XENTRY VCI C6 16-Pin OBD2 model, VCI main cables, Mercedes C4/C5 and XENTRY VCI C6 connections, the 38-pin vehicle adapter, and the heavy-duty vehicle socket set perform different physical tasks.
The same-looking 16-pin OBD end does not mean that the connector and pin structure on the device side are also the same. The Mercedes XENTRY VCI C6 16-Pin OBD2 model establishes the physical communication line between the compatible main unit and the vehicle or module.
The 26-pin D-sub device connector, the 16-pin OBD2 vehicle connector, the brand and part number of the selected variant, and the C4/C5 round socket cable are compared in terms of connector type, pin layout, and cable length, in addition to being different.
The Autocom CDP+ Compatible OBD2 Main Cable, Delphi DS150E Compatible OBD2 Main Cable, Ford VCM II Compatible OBD2 Main Cable, and Opel / GM MDI Compatible OBD2 Main Cable may be prepared for different vehicle sockets or service connections.
The Mercedes XENTRY VCI C6 16-Pin OBD2 model only performs the physical connection task; it does not add vehicle brand or service functions to the main unit's software.
Product details
The Mercedes XENTRY VCI C6 16-Pin OBD2 model package includes only the cable or adapters specified by name and quantity in the box contents. The 26-pin D-sub device connector, the 16-pin OBD2 vehicle connector, and the brand and part number of the selected variant are compared with the physical part upon delivery.
The package does not include a diagnostic tablet or vehicle software. If the Mercedes XENTRY VCI C6 16-Pin OBD2 model requires a main unit, the compatible device family will be specified separately. The warranty for the Mercedes XENTRY VCI C6 16-Pin OBD2 model is valid only within the scope of the purchased physical product and the described conditions.
