What is the meaning of MIL on the dashboard where oil and other indicators are displayed

MIL stands for Malfunction Indicating Light. It is also commonly known as the "check engine light" on other cars. This light coming on indicates that the on board diagnostic function of the car's computer has detected a fault or faults in the circuits that it monitors. This system is designed to alert you to problems that will affect the efficiency and emissions of the powertrain as well as other problems in other systems. These faults are recorded and kept in memory. It takes a code reader to read out these Diagnostic Trouble Codes or DTC's. Major auto parts stores will generally gladly help you by attaching a code reader to your car and getting the code(s). With this information, you can get a better idea of the actual problem and may be able to prevent the problem from becoming worse. Also, if the MIL light is on, you will not be able to pass an emissions test should your state/county require one.

Hello - I just bought a 2004 Jetta - day one - mil light came on. Car runs fine. What could it be? 2 mechanics checked the car over before I bought it and carfax said it was one owner no problems.

Have VW check it out. I had just got my 04 GLI with 70,000 miles when the light came on. The thermostat triggered the light and so I had the whole timing belt, thermostat, and water pump service. Worth the money.
