Roadi RDT45 Diagnostic Trouble Code Reader for VW

Reliable Handheld Automotive Diagnostics for VW and Audi Models
Beginning in the 1980s new vehicles began to be wired with a variety of computerized diagnostic systems designed to improve efficiencies, simplify troubleshooting and minimize the need for repairs. These systems produce indicators known as diagnostic trouble codes (DTC) internally, usually indicating something out of the ordinary by illuminating the “check engine”/malfunction indicator light (MIL) on the dashboard of your car. In the 1990s these systems, codes and the hardware connectors used to access them were standardized in North America as OBD (onboard diagnostics) and later OBD-II. Europe uses the equivalent EOBD, but Volkswagen and Audi vehicles also use another diagnostic standard system, VAG. Unofficially this acronym can be taken to stand for “Volkswagen Audi Group.”

The Roadi RDT45 VAG basic diagnostic scan tool is specially designed to work with most Volkswagen and Audis sold worldwide beginning in 1990. If your VW/AUDI model has a 16-pin OBD-II style Data Link Connector(DTC), the RDT45 code reader will certainly work. If it has an old-style 2×2 Data Link Connector (DTC), then it depends on whether there are 4 or 3 wires connecting to the pins. If there are 4 wires, each connecting a pin, then it will work. If there are only 3 wires, leaving one pin disconnected, then it will not. To use, simply plug the RDT45 code reader cable connector into the corresponding data port in your vehicle, usually located near the dashboard or gearshift, while the engine is off. Then switch the ignition on and scroll to the right menu option users can gain access to generic and vehicle specific VAG and OBD-II codes related primarily to the engine, transmission, airbag and ABS systems that trigger MIL events. Definitions for the DTCs can be found in your manual or via the CD definitions lists in on the CD included. Additional features include a USB cable for updating your computer-based definitions list and a nylon carrying case.
