VAG 2×2 to OBD2 16-Pin Diagnostic Adapter Cable

Connecting the 2×2 diagnostic port in older (1990 to 1995) pre-OBD-I vehicles to the OBD2 connector for current-generation diagnostic tools: this adapter is the bridge for the early VW/Audi Group estate that still fills workshops and enthusiast garages. The round 2×2 under-hood port goes in one end; the standard 16-pin OBD2 end feeds the modern tool.

Please note this is an adapter and not an interface — the phrase matters. It passively carries the vehicle’s diagnostic lines onto the OBD2 pinout; it does not translate protocols or add functions. What the tool can read depends on the vehicle’s own diagnostic output and the software’s support for pre-OBD-I VAG systems. Build quality is workshop-grade: the materials give the cable superior flexibility and durability for daily bay use.

FAQ

Will a modern OBD2 app work through it?
Only as far as the vehicle supports — pre-OBD-I cars output their own protocols; the adapter connects the wires, the software does the talking.

Adapter vs interface — in one line?
The adapter changes the plug; an interface translates the data. This is the plug.
