    Check the ETS unit in the trunk, under the parcel shelf, it should give you a fault code if the 4WD light is on. The LED will flash, just count.

    The code chart is in the service manual, page CH-67.

      Check reservoir in trunk for proper fluid level. Then try bleeding it

        I have the same problem right now. I am going to check the awd brain for some more info. What do all the codes mean?

        Also if you go to the search button and type in attessa bleed or bleed attessa, there is a guy on here Allen and he wrote a very nice do it yourself process on here. It was a little confusing at first but once looking at everything and finding all the stuff it was easy
        Miss driving sooooo bad! Need to get a car on the road ASAP!

          Note that you need to check the reservoir fluid level while ignition is in the "ON" position. If the car has been sitting for too long the fluid flows back into the tank and it will show higher than it actually is.

          Here are the codes:



          EDIT: Here are the manual bleeding procedures as well.

            ok great. thanks guys. im gonna have a look at this stuff tomorrow. i also had a friend take a quick look at it and he said my pump isnt priming when the key is flicked forward... he said i should be able to turn the key to on without starting and hear it prime/run like a fuel pump.
