    Enable Trailer Assist on MQB cars

    Hi all,

    the following script is a one-clicker to enable the Trailer Assist on MQB cars just by coding.
    This was already successful coded on a VW Passat B8, VW Tiguan AD or Golf MK7.5

    Requirements are of course a trailer hitch, a Trailer Assist capable rear view camera and of course a PLA 3.0 parking assist PDC unit.

    If you own AreaView, your rear view camera is capable of it.

    Code:
    StartVCDS()
    CheckForUnits("6C,69",1) ;RVC and trailer as a requirement otherwise error
    OpenUnit("6C")
    	TestComponent("Areaview",1) ; it is most likely that one already has the AreaView RVC
    	ChangeCoding("10:3","")
    CloseUnit()
    OpenUnit("10")
    	TestComponent("PLA 3.0",1) ; PLA required
    	LoginToUnit("71679")
    	ChangeCoding("0:3","")
    CloseUnit()
    OpenUnit("5F")
    	ChangeAdpChannel("menu_display_trailer_assistant","not activated")
    	ChangeAdpChannel("menu_display_trailer_assistant_over_threshold_high","not activated")
    	ChangeAdpChannel("Trailer_Assistant_0x36","not activated")
    	ChangeAdpChannel("Trailer_Assistant_msg_bus_0x36","Comfort data bus")
    CloseUnit()
    OpenUnit("17")
    	ChangeCoding("12:5","")
    CloseUnit()
    
    ClearAllDTCs()
    Cheers,

    The script had flaws. I edited my first post.

    Is "Comfort data bus" the right expression in the english VCDS version? At least that is what I found...

    And yes, the trailer_assistant channels should be deactivated except for the databus channel, otherweise there can be problems with the RVC.
    Feedback would be appreciated
