    I have had a major headache with this, i have replaced all the roof tray and components that are in the boot as i broke that. I have had a full VAGCOM rest done and when it read the code sequence for the roof open and shut it came up with this

    OPEN
    Address 26: Auto Roof (8H0 959 255 )

    19:19:31 Group 001: Convertible Top Status (Actual)
    Not Oper. Convertible Top Control Switch
    00100001 Switches && Positions I
    10 1010 Switches && Positions II
    30.0 Top Frame Position (G356)

    AND ALSO

    CLOSED

    Address 26: Auto Roof (8H0 959 255 )

    19:13:35 Group 001: Convertible Top Status (Actual)
    Not Oper. Convertible Top Control Switch
    00011010 Switches && Positions I
    10 1010 Switches && Positions II
    138.0 Top Frame Position (G356)



    Address 26: Auto Roof Labels:
    Control Module Part Number: 8H0 959 255
    Component and/or Version: VSG B6 CABRIO 6286
    Software Coding:
    Work Shop Code: WSC 00672 785 00200
    VCID: F3E0C3AC91AE891
    1 Fault Found:

    02000 - Switch Position
    008 - Implausible Signal




    Now apparantly the code sequence for the first few digits on the SWITCHES & POSITIONS 1 are wrong

    The first set should read

    00101001 but reads 00100001 (open)

    The second reads

    11011010 but reads 00011010 (closed)

    Please can someone tell me which microswitch or switches need changing if that is the case, many thanks in advance, Nick

    I replaced the G356 switch on my cab.

    It is a potentiometer locates in the main pivot point of the roof to body.

    They have brought out a revised switch since mine was made

    Part number: [TABLE="width: 493"]

    [TD="width: 238"]Top Frame Position Sensor [/TD]
    [TD="width: 255"]8HO 959 613 A
    [/TD]
    [/TABLE]

    its about £60 expensive for a switch, but i don't get any fault codes now.

    This was my faults:
    2 Faults Found:
    02000 - Switch Position
    008 - Implausible Signal - Intermittent
    01986 - Convertible Top Frame Position Sensor (G356)
    008 - Implausible Signal - Intermittent
