    hi all
    i have a 2002 audi cab and the other day i put the roof down with a suit case on the back seats, the roof touched the suitcase where it folds inside the rear seats then stoped its procedure, i had to then put it up manually . now when i go to put it down the windows just drop normally but the roof doesnt move i have done the manual reset in the handbook with no luck
    this evening i plugged it into my mates computer and got the following codes
    02000 - switched positon not a plausable signal
    01996 - cabrio top lock switch -f294 open not a plausable signal
    01995 - cabrio top lock switch -f295 closed not a plausable signal

    cleared the codes and roof still wont work and 2 of the codes have come back

    any ideas will be welcome
    thx shane

    F294/295 are located at the front of the roof behind plastic trim. Not done one in a while but i believe both switches are built into the latch unit. These are just to allow the control unit to know the position of the latch. if it dosent know the position it wont work. If you have vagcom check measure value block 07 of roof electronics. If i remember right the value 1 is the readouts for them. Will possibly req replacing if not operating correctly

    When operating the roof switch, watch the values in the measured value block to see if the switches are reading correctly. does the roof lock and unlock when operating the switch?. Try manually unlocking and lowering the roof to its open position, then operate the switch to close it.

    Go to measured value block 1. On readout 2 will be the list of switch states in binary form (1 or 0). This reading should be 8 digits long (8 switches). The ones you need to pay attention to are the 5 and 6th ones from the left. The 5th one is the open position and the 6th one is the closed position. These should change when manually operating the lock from 0 to a 1. For instance, when unlocked it should look something like ( xxxx10xx) and closed (xxxx01xx). Don't pay attention to the other numbers just these. You need to do this to see if the switch is giving the correct position at the correct time. If it doesn't then it wont work the roof. Have fun!

    yes i sorted the problem by manually opening the roof then pulled the roof switch to the open position and turned on the ignition and kept the switch pulled for 20 seconds that set the open postion then closed thew roof manually pushed the button down turned on the ignition kept the button pushed for 20 seconds again to set the locked position

    this may help some of you guys out at one point

    Any help guys
    problem with my roof not closing. It opens all the way but when i try to close it it stalls with a few inches from locking. The roof light flashes on the dashboard:

    Did a full manual reset but to no avail. the roof goes down and the first time it closes ok. However, when you do this the second time the same thing happens and the roof light flashes on the dashboard.

    Plugged in the diag tool and it comes with these three errors. even if you reset them they reappear.

    02000 Switch position not a plausible signal
    01996 Cabrio top lock switch - F294 Open Not a plausible signal Intermittent
    02024 Perfom adaptation No or Wrong Adaptation


    PS: the near side latch that holds the sensors was replaced last week from Audi

    Hi all,

    Im having an issue when closing the roof on my A4, basically it closes all the way with the electronic switch, but for some reason it doesn't register that it's closed. The windows don't roll up and then as you pull away it beeps and says soft top not secure!

    If I turn the ignition off and leave the car for an hour or so it seems to reset and it doesn't say "soft top not secure".

    Im guessing its something to do with the closing switch F295? But I'm not sure?

    any help would be much appreciated

    Sean

    The instructions below worked really well, with one addition. The first time you go to open it, you may need to manually unlatch the roof-locks with the key. Once I did this, all working fine again.

    Another tip.... don't feel inclined to 'help it along' as it tries to open/close. The interlock circuits will detect this and stop the whole thing again.

    Therefore, the sequence I used was:-

    Manually put roof down (away in boot).
    Ignition on.
    Hold button to 'Roof Down' for 20secs.
    Ignition off.
    Manually put roof up.
    Ignition on.
    Hold button to 'Roof Up' for 20secs.
    Ignition off.
    Ignition on.
    Try to open roof, and use roof key to release roof if it doesn't release itself straight away.
