Body, Paint & Styling Sunroof opens on its own...

    Hey there. This is a weird problem.

    I was driving my car today and everything was going well but then after a minute the sunroof opens on its own. It didn't actually open but it went to the tilted position like when you push on the button.

    I cannot close it with the button so I closed it manually. When I switched on the electricity the same thing happens again, it went to the tilted position. I then proceeded to open it manually, switched on the electricity and closed it. It closed but as soon as it closed it went back to the tilted position...

    Anyone had a similar problem? Tried searching the web but I didn't find anyone that had a problem like me.

    Sorry if my English is bad, it isn't my first language...

    I haven't come across the issue before, but given the location I would assume water has got into the button housing and is bridging the two wires for the tilt button. Is the area moist at all to touch?

    No, not at all. Thinking about popping it into the garage to let it defrost and see if it will help at all...

    That's probably a good shout, water could also be bridging the wires further along the chain as well, doesn't necessarily have to be the button housing.

    Nothing has changed. Going to take the fuse out and take it to a repair shop, this is out of my league :Tongue:

    It's an odd one for sure.

    Keep us updated on the situation @Sibzter

    Update long due.

    I took it to a shop and asked them to try to find out what was wrong. They measured all the wires and checked the ground. Everything is working good so they wanted to read the computer but they couldn't connect to the car.
    They didn't charge me for the work and I am going to take the car to the dealership a week from now.

    The culprit maybe some motherboard or control unit something something...

    Another update. Went to the dealership today, they found nothing. They want to order some necessary relays and other stuff before they start to tear the headliner off.

    They said it'll take about three weeks for them to arrive.

    This is probably one of the most odd cases we've had, good to hear the dealer is gathering supplies for a proper look into it though. I'm almost out of ideas!

    Alright another late update. The dealership found nothing, all relays worked fine.

    Next step is to order a new assembly for the sunroof, motor and control unit. That alone will cost me £ 250 not counting the labor. I don't think it's worth it so I guess there is nothing more to do but to weep ;(
    Upside is that I haven't had to pay for the other work they did.

    How did you close it manually?
     
  12. Sibzter Junior Member ☆ ☆ ☆ ☆ ☆

    There is a tab right next to the dome light, you rotate it with a flat screwdriver and that will expose the mechanism to close it. There are tools for this on top of the spare tyre (atleast for me). Then I believe it's a socket that requires a hex key (again, there should be a tool for this on top of the spare tyre). Then just insert your hex key and rotate.

    I am not able to close it 100% percent, otherwise the sunroof opens. Removed the fuse for the sunroof and closed it 100%.

    I assume you have tried sliding it open and then closing it, to see if it resets.

    Isn't there a way to reset the ECU by disconnecting the battery for a length of time. May be worth a try, to see it has any affect on the sunroof.
     
  14. Sibzter Junior Member ☆ ☆ ☆ ☆ ☆

    Yes I've tried that.

    My alternator decided to fail the other day and my battery was out of the car for about 3 days, didn't reset it :/

    Very strange one that, could you not get good second hand spares to keep costs down?

    Another thought is to take the car to an auto electrician, as to me this still sounds like a wire that is intermittently shorting to ground/ chassis, have you had a new windscreen fitted before this happened? if so just wondering if the inner trim that runs up the A pillar was removed and on refitting has crushed one of the wires and as the body of the car flexes is causing this wire to short to the body.
    Cheers Pete

    I must admit it does sound switch gear related rather than anything else.
    For some reason the sunroof controller is being fooled into thinking the open roof button is pressed. Have you tried disconnecting the sunroof switch altogether to see what happens? Usually these things can just be a process of elimination.
