• My little Forester continues to be fantastic, so much fucking fun, took it to the car wash today, looks beautiful, etc, blah, blah. But I'm still getting an intermittent check engine light with a B0E04 knock fault code. Internet tells me it isn't a big deal, could just be a dodgy knock sensor, ECU corrects the knock anyway, etc. My wrench guy doesn't seem worried.

    What should I do? What does the car thread hive mind think?

  • Could be a wiring loom thing, a sensor thing, a ground wire thing....the intermittent nature makes me think its a wire thing. No luck on Scooby forums?

  • I've mentioned it on a couple of the SF5 groups on FB, so many answers and it could be absolutely anything. Haven't had a major red flag from anyone tho', I just wanna make sure I don't cook the motor.
