    Case Study: A5 / S5 Audi Cabriolet top issue B11A0

    Suggest you folks get the Audi training guide:

    The 2010 Audi A5 Cabriolet
    Self-Study Program 960193

    Address 26: Auto Roof (J256) Labels:| 8F0-959-255.clb
    Part No SW: 8F0 959 255 HW: 8F0 959 255
    Component: VSG-AUDI-B8 H09 0170
    Coding: 030000

    ASAM Dataset: EV_ElectRoofContr 001007
    ROD: EV_ElectRoofContr.rod
    VCID: 71E3D33AA01827CE75-8024

    1 Fault Found:
    0004 - Switch for Convertible Top
    B11A0 02 [137] - Signal Failure
    The cabrio top does not seal up the back end correctly. The curved hoop below the rear window is the "Tension", there small gap between it and the convertible top box lid.

    The Auto Roof (J256) has to see the Convertible Top Closed Position Switch (F202) is "operated" before it will hydrolic cylinders that push the tension down firmly onto the convertible top box lid. The F202 data will be found in Advance Measuring Values:

    IDE02664-MAS02264,Switch for folding top-Convertible top front closed position switch

    The F202 is located on the right side of the frame, maybe 24"-ish from the front edge. It is on a plastic mount that is secured to the frame. The plastic mount can bend/flex so that the F202 is out of alignment and doesn't get "operated" when the leading edge of the top is flat. You may be able to grab the frame in the area of the F202 and push/pull on the top that the switch becomes "operated" and then a helper and flip the power roof switch to close and the rear tension will gets pushed down as it should.

    The fix for this may be as simple as using epoxy to help glue the plastic mount that the F202 is on flush with the frame so it can no longer flex out.

    The F202 location, on the right side of the frame.

    Recently had (and finally resolved) this issue myself.

    In Jef's photo of F202 above, you can see a metal tab just below and to the right, on a different part of the hinge. That is what F202 is detecting ... it's just a regular piece of steel, I believe. (If you monitor F202 with VCDS[1] while the roof is half-opened as in the photo, you can see it turn on and off as you hold a screwdriver up to the face of F202.)

    There are two torx screws on the interior side of that piece that allow for a significant amount of adjustment. I had to adjust mine a few times (pushing up or pulling down on the roof gently in that spot if it refused to operate). I just moved it a hair each time because I didn't want to risk breaking anything. There's a sweet spot, so when you think you've got it, cycle the roof a few times to make sure it's happy before putting away your screwdriver and laptop.

    If anyone would like detailed instructions on how to manually operate the roof using the hydraulic motor and the output test of VCDS, please contact me directly and I'd be happy to explain. I've also got the sequence of all switch operations needed for normal opening and closing of the roof, with some approximate timing information.

    Raw notes for posterity

    I was recently contacted by another forum member looking for assistance with a 2010 series Audi A5 Cabriolet roof.

    Until I get around to typing these up in a friendlier format (if I ever do), perhaps my raw troubleshooting notes from last year may be of use to others in the future. I make no promises that any of this is correct, legible, or sensible, but it did help me repair my own vehicle.

    Cheers,

    - Jim


    Linked PDF and CSV files:

    1. List of all sensors with UDS 'IDE/MAS' numbers cross-referenced to VAG component identifiers (e.g. IDE-02264-MAS02263 is equal to F171*)
      (this also contains my best guess at sensor sequencing, which is also reproduced the image below)

    2. CSV files containing sensor timing information for an incomplete opening/closing operation. Split into two parts due to limitations on the number of UDS items VCDS could log at once:
      Part one. Part two.

    3. Annotated hydraulic drawings for the opening (4 steps) and closing (5 steps) operation sequences; one step per page.
      (Note my correction of the drawing for the third step of the closing operation ... it should have read "Lifting the tensioner")




    (Again, these were just my raw notes for my own use, so please forgive the sloppiness.)

    * Note: These may change over time, as I believe my logs from several years ago (after the first module firmware updated that switched to UDS mode) had different numbers.
