The time has arrived where anyone can now diagnose their car, easily and affordably! Here is an adapter that does all of the hard work of protocol translation into a simple ASCII character based view.

Via the included serial cable, this adapter is used as an interface to connect virtually all OBD-II compliant vehicles to a PC for on-board diagnostics (OBD). Such vehicles are VW, Audi, Seat, Skoda, Opel, Vauxhall, Alfa, Mercedes, Smart, Renault, BMW, Peugeot, Citroen, Lotus, Ford, Rover, Aston Martin, Ferrari, etc.

You can also use it with many other software products that require a ELM327 compliant interface, examples of which are listed below in the Supported Software section.

  • ELM327 v1.5 Chipset based design.
  • Supports 9 protocols in all - SAE J1850 PWM, SAE J1850 VPW, ISO 9141-2 and ISO 14230-4 as well as CAN Bus ISO 15765-4.
  • Precision-moulded diagnostic connector made to fit all VW/Audi vehicles, even those with "tight" trim around diagnostic socket.
  • USB port design.
  • Internal EEPROM can remember the last protocol.
  • Voltage input monitors your vehicle's battery.

Please note that the interface supplied may look different to that photographed in the description.
