Hi,

For many CEL's once the fault is corrected, the light will go out. Others require disconnecting the Battery negative terminal (radio code in hand) for 5 min. This will cause the DME to reset also and the Tiptronic control module, so these will run rough or shift differently for the first drive cycle, usually 5-10 miles. Finally, major faults need to be reset with a PST2 Tester, Durametric software and some OBDII scanners. Hope this helps...

Happy Motoring!... Jim'99
