Engine Management On
 

Hi Everyone..... ( Blobeye Wrx 2003)
On the way home my little Engine light popped on without any warning.
I stopped the car to have a look and the only thing I noticed was the vacum pipe going to the top of my dump valve had come off. :wonder:
Would this make the engine management light to come on?
The car drives great but after putting the pipe back its still staying on.:confused:
Im a also right in saying that the light might need to be reset?
Can anyone answer these questions as im a little worried as this hasnt happened before.
Thanks
Gandy
