    This is a guick guide to find the VANOS related functions in DIS. :thumbsup:

    There are 3 useful VANOS functions in DIS:
    1. the VANOS test
    2. view adaption
    3. clear adaption (useful after repair etc.)

    It seems unless you have any related fault codes stored then it's quite tricky to find the related functions.

    This is using DIS v44, specifically the "easyDIS" image floating around.
    Before anyone asks, I don't know if this works in v57, haven't tried :p


    Initial setup, aka the IMPORTANT bit :roflmao:

    The "protocol translator" must be set to "Fister" (the default is "Softing").
    This is important, I couldn't get past step 8 below without doing this first!
    To change protocol you must drop back to the "EASY-DIS CONFIGURE-MATIC MAIN MENU" is DIS, note this is not a standard part of DIS (hence the screen looks completely different to rest of DIS), it is an extra added by the nice fellow "Fister" of bmwecu.org (so says the menu's title anyway!)

    [​IMG]

    To do this, from the DIS start screen, click "admin" button, then "Touch Screen Calibration" button, then enter password: 12345.
    Once in the configure-matic menu: go option [3] "Configure Protocol Translator", then [3] "Change translator to FISTER".
    Now we need to either:
    [1] "Restart EDIABAS", then [9], [9] again to exit back to DIS.
    OR
    [9] "Exit", then [0] "Shutdown DIS". DIS will now shutdown completely and your VM will close. Open it back up again and wait for DIS to boot up.


    Finding the VANOS functions

    With the correct translator set, we can proceed to the VANOS stuff:

    From DIS start screen:

    1. Click "Diagnosis" button.

    2. Select car: click "3 series", then "E46", then bottom-right green arrow.

    3. Click "OK" on next screen.

    4. This screen shows all the modules present in the car, click "Short test" and wait few minutes for it to finish, the click bottom-right green arrow.

    5. Ignore whatever this screen says, instead click "Functon Selection" button, bottom left.

    6. On this screen, drill down to the DME: in "Functions" menu (left menu) choose "Drive", then "Engine". Now in "Engine" menu (middle menu), click "Digital Motor Electronics", don't go down any further, just leave the "Digital Motor Electronics" highlighted black. Now click "Test schedule" button (bottom middle).

    7. On next screen just click bottom-right green arrow.

    8. "Please wait ..." message appears, after few seconds your dme information should appear! (if it fails, see the initial setup bit at the top :eek:)
    Click bottom-right green arrow to proceed.

    9. You should now be in the DME menu with 4 options: [1] Fault symptoms, [2] Function test, [3] Service functions, [4] Expert mode.

    [​IMG]

    All the VANOS related stuff is accessed from here, so depending on what you want to do next:

    10.1. To view vanos values and adaptions:
    [4] Expert mode -> [1] Diagnosis requests -> [16] Vanos (scroll the list down to get to this option). Note on the initial screen that shows up, you can click bottom-right green arrow to proceed, then use the up/down green arrows to go through 5 screens of diagnostic information.

    10.2. To clear the VANOS adaptions:
    [3] Service functions -> [13] VANOS: reset adaption

    10.3. To do the VANOS test:
    [2] Function test -> [1] VANOS test
    Note, engine must be running and warmed up (DIS gives you the required and current oil/coolant temperatures on the next screen)


    The VANOS adaption screens:

    As long as everything reports ok it should be within tolerance.

    I wouldn't bother resetting it if the test shows it's ok. You also need to be up to temperature for oil and water or it won't run, the green arrow just loads and doesn't do anything. Over 75 degress for both afaik.

    60 degrees dephasing for both the inlet and outlet. They should go from 60 - 0 and 0 - 60.

    Fixed:

    60 degrees inlet.
    45 degrees exhaust.

    The screen capture shows 48 degrees on the exhaust. Are you saying that's a problem? DIS says the test passed.

    I saw 60 degrees dephasing when I tested mine after having the VANOS off. Unless I'm dreaming. Might have to try it again.

    This was while driving, though. Maybe the test doesn't go that far. I've just looked at a couple on youtube and they also get 48 degrees so I guess it's a correct value.

    So I had a look at the BMW technical information for the S54 engine and the adjustment ranges are:

    Inlet: 60 degrees.
    Exhaust: 45 degrees.

    So apologies for earlier post.

    Glad it's 48! Thanks for the update!
