    VW Passat 3.2 FSI - Idle speed tweak. Need some help.

    Hey all!

    What a first post this is going to be. Somewhat scared and excited

    I'm from a relative shameful background.
    Myself, as I think quite a few people don't care to admit, started out with a eBay-version of the VCDS-interface.
    Lately, I've come to realise that I'm not actually a thief, and acknowledged the fact that people have worked tirelessly to develop both hardware and software (Even though the seller swore it was a genuine verison). So, I bought the new HEX-V2 directly from Ross-Tech. It is reasonably priced, and I wanted to "repent" my sins. Despite this (Which I actually didn't have to share with you, but honesty lasts longer, I'm lead to believe), I hope you'll welcome me in reaching me a hand on this one.

    So hey, here I am.

    When I had the chinese version, I think the software was limited to ver. 14.1 - I've done several mods on my car, and one which I did was to enter the engine module 01, and change the idle speed from the adaption menu.
    Now, I get sporadic air-flow errors whilst idling, and sometimes clutch engagement from standstill seems "edgy", so I want to change the idle speed back. It was 800rpm to begin with, and I changed it to 600rpm. Don't ask me why - Because I honestly don't know.

    Anyway, I tried changing the idle speed back to normal, but now when I open Engine 01 -> Adaption -> Idle speed, it says I need a security access code.
    I can't remember if I ever entered that on the 14.1 version, but I'm used to a pop-up showing the corresponding security access codes. This pop up does not show on the latest version.

    I tried code 12233, and the engine control module locked up. How do I find the appropriate code?
    The car is a 2010 VW Passat 3.2FSI (AXZ engine code).

    All help will be very appreciated, thanks!

    Welcome.

    An Auto-Scan is relevant, so people can see exactly what ECU you have.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Alright boss, I'll update this as soon as I'm back home. ~2 hours and it's done

    OP updated with auto-scan.

    This is what I struggle with.
    First, I get into the engine control module, and press "Adaption".



    From there, I choose "Idle Speed Adjustment"



    Which leaves this error message.




    As stated in OP I do not know the security code, and the pop-up that usually shows the corresponding security codes does not show.

    Hmm... I went back and looked at the older versions, 12.12 and 14.10 and I don't see where a security access for that has ever been documented, nor do I know one. Yet you say you changed the channel at some point? I'm scratching my head, wondering how that's possible without one.

    Would you mind having a look at MVB 056 while the engine is idling? That will show both the actual idle speed and the currently specified speed.

    Absolutely.
    Measuring group 056 says:
    Engine speed actual: 640 / 650rpm
    Engine speed specified: 650rpm
    Idle regulator: -0,6%
    Operation condition: 000101


    When you ask that question, I start to second guess myself.
    Not about the idle adjustment, because I remember that clear as day.

    But, if I did it from the adaption menu, I'm not sure.

    OK, so your engine is idling at the "specified" speed.

    I can't think of any way to do the idle adjustment other than via Adaptation. And it's not VCDS demanding a security access; that's the ECU itself.

    Hmm.

    So there's no way I did that adaption from VCDS back then?
    How on earth did I do it? I sometimes hate my goldfish-like memory..

    Well, it is possible you found one somewhere on the 'net that we don't know about.
