    2006 EOS 2.0 FSI - No operation of trunk, roof or sunroof

    Hi All,

    Hoping someone can help me out.......

    I have a 2006 EOS 2.0 FSI which has recently developed a fault where the trunk, roof and sunroof all fail to operate, like there is no power to any of them. I did some checking yesterday and can confirm that there is a 12V supply to one of the connectors on the roof controller. However, I also discovered that the high level brake light has been letting in water and there were signs of corrosion on a couple of the electrical connectors - nothing too bad and they cleaned up quite easily with a small brush and some switch cleaner.

    I have purchased and registered a Ross-Tech HEX-V2 and downloaded the latest VCDS software. My log file is as follows........

    There are quite a few faults showing which I will investigate in time, but I'm particularly concerned with the convertible top control module (J256) which shows as 'no signal/communication'. Obviously without being able to communicate with it, I'm struggling to diagnose my roof issue.

    Can anyone help??

    You're going to have to figure out why the roof module is off-line. The car's gateway can't see it:

    25-Immobilizer -- Status: OK 0000
    26-Auto Roof -- Status: Cannot be reached 1100
    37-Navigation -- Status: OK 0000

    And VCDS can't access it either:

    Address 26: Auto Roof
    Cannot be reached


    So the next thing to do is check power, ground, and CAN bus connections to the module with a multimeter per wiring diagrams.

    -Uwe-
    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Fuses first..........

    Clean and investigate visually or isolate the water ingress.........be sure no puddle in spare tire area causing a rain effect in modules of trunk area.
    When corrosion is present, this usually means this has been going on for some time now depending on how heavy and what reacted.

    Better have a look at WD in ERWIN to see what tracks are shared like Uwe aforementioned.

    Hi Uwe,

    I've done a bit more investigating on this.....

    Can confirm that there is 12.4V at J256 - Convertible roof actuation control unit. This was present on plug B, pins 1 & 3. Also have good earths on pins 4 & 6. This was done according to the following pin info:

    Code:
    G558 -    Sender for left roof member locked 
    G559 -    Sender for right roof member locked

    What I did find was that on 16-pin connector D, pin 2 (Convenience CAN bus low) There were some light traces of oxidisation present. I have cleaned this up and it looks fine now. From what I have been able to work out, the CAN bus circuits should be around 4V. I did a quick check on both pin 1 (Convenience CAN bus high) & pin 2 (Convenience CAN bus low) and the showed 0V & 12V respectively. On operating the remote boot open button on the fob these reading changed to 0.7V & 4.5V respectively.

    I am very very far from an expert on CAN bus, but this doesn't seem right from what I can tell. I'm going to put the VCDS back on it over the weekend and will post the log again.

    Based on the above, can you think of any thing obvious I should look at?

    Did you take module apart to inspect the progression of water ingress to the board from where you observed it on or at connector?

    If this is above your scope change the module.

    Hello Jack,

    I did take the heat sink off the back and couldn’t see anything out of the ordinary but I didn’t take the PCB off to check the back of it. Will do that on Sunday and report back.

    Thanks for your help so far.

    BTW, paid for an hour on Erwin and saved a load of wiring diagrams, so I’ll also try and work through them too.
