engine management light
Hi i got a 06 wrx couple of weeks ago it had a mushroom filter on it,i drove the car with no problems but now the engine management light has come on so i put the air box back on but the light is still on can u give me any ideas to what it might be thanks alot.
ps. as i know car is standard except from cat back exhaust and dump valve. cheers.

Changing the Filter doesn't always give a CEL because the DENSO ECU that you have is fairly clever at sorting out the airflow........having said that the ECU you have tends to have a hissy fit for no apparant reason sometimes.
Have you revved it anywhere near the rev limit, the ECU sometimes gets confused and throws a camshaft position sensor error !
That's why you really need to get the code read...

are you sure all your cat converters are there ? my light is on due to having a full decat system but thats on an 02wrx . not sure how much a garage will charge to tell you fault ? but i know some will sting you as you are at their mercy . i bought a "v1 monitor" for 130 and it tells you fault codes and if like mine its something simple and nothing to worry about you can turn the light off yourself in seconds 
then there is the 0-60 , quarter mile,bhp figures,boost,air fuel,temp,g-meter,shift lights etc etc to name a few . at least doing it this way you have piece of mind knowing exactly what the problem is 
it simply plugs under steering wheel in your obd port and gives you the fault code and a brief explanation of the fault

think i read on here the dump valve can also put the light on as some subaru`s don,t like them..
shame your not near me in peterborough as i have a fault reader and it also turns the light out
