Anyone know how to turn off the Check Engine Light
As above mentioned, to reset your check engine light you need either the above, or a Handheld unit (I have Palm and Visor) with a "Injector Clean Cartridge" around $380 Canadian).
The shops and dealerships are using OBD II Scanner by the way. (Even VW).
Here is some food for you thought, though:
1) If you reset that light, and there is really a problem it will come back on (could be 1 minute or months after the reset)
2) Make sure you get the codes when reseting yourself or with a buddy, and reset it as "Remind me later option" don't clear it from the memory of the System.
3) Good luck.
