Audi 2006 check light on? - Cars & Trucks
When the service engine\012soon light (Also called the check engine light or engine management\012light) is turned on this is to alert you to the fact that Powertrain\012Control Module (computer) has detected a failure somewhere in the\012systems it controls you may not feel any difference in the way the\012engine runs, this can be the transmission or the engine or emission\012system, there are fault codes set in the modules memory for these\012faults. What needs to happen now is to have the powertrain control\012module scanned with a special tool called an OBD2 electronic engine\012control scanner or a OBD2 code reader. Once the code(s) are read then\012you must perform the diagnostics for each code and make the\012appropriate repairs based on the findings of the diagnosis that was\012performed, this is called doing "Pinpoint" testing.
