VW VAGCOM scanner. Save hundreds of $$$ with this hand held scan tool. Don't pay a dealer to clear check engine lights. Most cables simply connect your car to a laptop computer; no computer is needed with this handy tool. It is compatible with all OBD II VW's, even the latest cars that use a CAN-BUS system. It reads and clears DTC's (Diagnostic Trouble Codes), resets check engine lights, and more! Power is even supplied from the car through the OBD II cable, no batteries needed! For a more robust solution see SN24403!
Even though the VW VAG scanner can turn off your check engine light, you shouldn't only use it for that function. Make sure you have Bentley manual so that you can learn what the different codes mean and how to fix them. Continuing to simply turn off your MIL lights is not the proper way to fix your car and can lead to much bigger problems down the road.
