It's me again. I have searched in here on how to reset the Check Engine Light
but I guess I didn't search hard enough. I know it's out there somewhere but
maybe if someone help me, it will cut the searching time! Anyways, I plan to
make oil change this weekend as well as replacing the sparks plugs and filters.

I believe the Check Engine light came on because I refuel my 2000 A4 while
the motor is still running. Because the error says something about Air/Fuel
Mixture.

Thanks a bunch!

unplug you barttery have you radio codes. the other way is to find someone witha vag com and get him to clear it

 

make sure you have your radio safe code if you unplug the battery, it is very expensive to have the code "retrieved" by the dealership...autozone has a generic OBD2 reader that they loan out for free (most will make you put a deposit down though) that you can use to reset the code...a/f CELs often mean you have a failing O2 sensor, you may want to get that checked out, but it could also just be because you refueled with the car running (which is kind of stupid, i wouldn't recommend doing that anymore)

 

Why do you keep your car running when you fill-0up.

Have someone pull the codes and post them here. As mentioned Autozone can pull the codes and reset the CEL.

Could also be a bad mass air flow sensor

 

thanks for the reply guys.

 

or somthing as simple as a leak

i try to look on the bright side
