Reset MIL light VW GTI

If the vehicle is 1996 or newer, then you will need an OBD II capable scan tool. If it is older than 96, it will be using an OBD I scan tool. Follow the directions on the scan to remove the codes. On some older cars, there is a procedure to turn the light off, for instance press brake pedal 3 timesw/ignition off, then turn on ignition, turn off and on again. The MIL means there is an issue with some system. Turning off the light will not fix your problem. It can be as simple as a gas cap not being tight to your torque converter clutch failing. Find out why the light is on and fix it. Don't just turn it off and assume that the problem will go away.
