    Did you read the PDF file listed above? Page 162? It talks about the FCV.

    I read the 162 page and there's nothing about fixing. If i disconnect the fcv it' s still damaging the battery.

    Quote from page 162.
    "vFCV disable per Geordi The best thing you can do for your engine is to take the FCV off the intake elbow and unscrew the big butterfly disc from the center of it. Now, it can never close again and fork up your engine. It has NOTHING to do with a 'soft shutdown' or doing anything at all to prevent a possible engine runaway. It COULD, but the requisite programming and sensors don't exist in our CRDs. It is ONLY there for the emissions control crap."

    Sorry, I'm not a CRD owner and never worked on one. All the info I've provided is search based. The information above is related to engine shutdown and FCV noise. Do you have a battery drain issue? You may need to pull fuse by fuse and check amp battery draw. Once you find what stops the draw, you can check the components tied to that fuse.

    I've checked the fuses. Noise stops after pulling the asd fuse.

    ASD - Automatic Shutdown Relay
    The fuse you pulled is the signal to activate the relay. The relay then powers every accessory on that circuit.

    Replace the relay with another similar relay. It's to check that it's not getting stuck. You can power it with 12 volts to check if it clicks.
