    T5.1 Cruise control retro not working

    A mate has a T5.1 and got a cruise kit with instructions to fit
    Unfortunately the instructions didn't show how to update with VCDS, it looks like dealer software so we googled how to set the cruise on

    First problem:- The guides say to LOGIN to the engine ECU but the LOGIN button is greyed out, any idea why?

    Checked using the long coding and found it possible to set cruise fitted so did that.

    This is a scan from before fitting

    Looking for ideas for what might be wrong, I don't have access to the van right now to double check the wiring so pointers or ideas

    Should we be able to use the LOGIN button?

    The old Login function simply doesn't exist on modules that use the UDS protocol, which your ECU does.

    You should probably tell the BCM that there's a CCS installed too (Byte 17).

    Then check CCS switches in MVB 004 of the BCM.

    Yeah code byte 17 bit 7 and the engine ECU for cruise control and you're good to go.

    next question, what should we do here when trying to update the BCM to have the CCS

    Following message appears:

    VCDS: Re-Code Invalid
    This appears to be an unintialised control module;
    valid WSC/Importer/Equipment data may be required.

    Click [yes] for VCDS to use default value of 12345/123/12345.
    Click [no] for VCDS to try the values currently in the module.
    Click [cancel] to go back and manually edit the values.


    What will happen if we say yes?
