    2011 Headlight issue after Cobb AP install

    Don't know if anyone has posted about this issue so if there an existing post please help me.

    I just received my Cobb AP (SUB-003) yesterday and installed it. I currently have a Cobb SF Intake w/ Box as the only modification on my 2011 WRX. I installed the Stage1 93 Octane Normal Wastegate Rev. #3.10. After it successfully installed, I noticed an issue. My headlights stayed on after I turned the car off and take the keys out of the ignition. As I remember, they always shut off automatically once I turn the car off. Other than this issue, the MAP install works great and I definitely can say it corrected the boost delay I had before the install. Please help!!!

    That is strange. Maybe a relay issue?

    I can't see this being an AP issue. I agree with a sticking relay.

    How do I go about checking if it's sticking or not? Sorry, I'm still a noob.

    I'm not sure what you're trying to say. Do you mean to install the Stage 2 MAP?

    A relay is a relay. Doesn't matter what it is used on. Car,machine,industrial,home,electronics. If you know how a relay works it's pretty easy to troubleshoot.
    Relays

    Obviously if the "switch" wire is not energized and the component the relay controls is still operational,this would be considered a "sticking relay" as it is stuck in position allowing voltage to pass through. Though some do use the ground as the "switch" wire. Subaru does do this sometimes. So you need a schematic for the headlight wiring to know which wire to check. Or you can just spend $5-10 and swap the relay with a new one. Should be a SPST.

    I'd take that sucker back to the dealer. It is a bit different than the older subies, however.

    Correct behavior (to my understanding):
    -If car is on with headlights on, and you shut off and take key out, lights go off regardless of your control (I believe yours is not following this)
    -If car is off with headlights on and key out, you can turn the headlights on and off (different than older models to my understanding)

    Also, if it is the DRLs you are talking about ,pull the E brake & they go off. If the E brake is released they stay on.
