Hi there!!!!

I know there´s a lot of skyroof posts around here, but I have a very specific problem.

You´ll see in this video my problem

youtube.com/watch?v=XLl7k3fRVlM

About a week ago the skyroof stops working, and if I push the button to reset it, makes hell of a noise in the curtain motor.

Today I opened the curtain and the roof manually, still no response fron the curtain button or the roof wheel. Pushed the wheel for 10 seconds and the glass panels starts to close, but not a smooth movement, but start-stop movement until is finally closed, then the curtain starts closing, when is completly closed, noise again coming from the rear motor and no response from the open-close wheel-button.

Any ideas????

Thanks a lot!

Hi Danny,

Is the noise definitely coming from the rear motor?

It looks like the anti-trap sensor might be going off, were you regularly maintaining the mechanism and greasing the runners?

Hi there Yellow! Thanks for answering!!!!

Yes, the noise comes from the rear motor, the curtain one, and I grease the roof twice a year, at the beginning of the winter and at the beginning of summer.

Where´s located the anti-trap sensor? In order to check it out.

Greetings

Hey Danny,

not sure where the sensor is but I think it works from the resistance of the roof closing against the runners, hence the question about greasing.

Have you observed the front motor to check it is consistently turning as your implement the reset procedure? I am wondering if you have stripped a couple of teeth from the drive cog?

Otherwise I wonder if it could be failure in one of the control boards on one of the motors?

The anti-trap sensors are located in the blind and roof motors. They are hall effect sensor that monitor current consumption of the motors and speed of operation.

They can be tested (on a working roof) by pushing backwards on the front edge of the second glass panel while it's moving forward, in which case the roof should reverse 200mm. Or by pushing upwards on the rear edge of the front glass panel while it's lowering, in which case it should stop.

The same method can be used to test the blind anti-trap sensor. It should also reverse 200mm when obstructed.

According to the eLEARN description, the anti-trap sensors can be overridden if the rotary knob (when in the "0" position) is pressed within 5 seconds of the roof stopping. The overide should remain active until the roof is fully closed or until the knob is released.

I would not recommend trying the overide procedure if there's any suspicion that the motor's gears or roof operating rack cables are damaged.

Hi there!!!

Weekend update.

Today I worked on the sky roof. Opened the curtain and the glass panels manually, then removed both motors, then put the rear (curtain) motor in the front, and the front motor (glass) in the rear. The motors are the same, the only thing that change is a plastic part that can be switched from one motor to the other. Then tried to close the roof and the curtain with the buttons....... nothing happened. Then pushed the wheel button to reset the sky roof, same thing that happened in the video, close step by step, not continous movement. Finally the roof and curtain are got closed, try to open it.... nothing happened. Reset the roof by pushing the wheel, noise again from the rear motor and nothing moves. I think that the mechanism is "thinking" that the curtain is not fully close and is attempting to closing it, thats the reason to the rear motor to keep pushing the curtain. so I don't know if there is a "close sensor" or something like that that could be the cause of the problem.

The front and rear electric motors may look the same but they have different ECUs built into each of them and are not interchangeable. The two ECUs interact with each other to keep the blind and glass plates synchronised.

Hi there

Just had problems with my 06 stilo skyroof as well, lots of crunching and grinding from front roof motor not able to reset etc. Had to close roof with manual winder bar.

Taken it to a main dealer today in the southeast and have been told it's dead!
The cheapest option i've been given is a complete new roof for just under £3000 this must be more than the car is now worth.

Any ideas would be greatfully received :idea:

Hi there!
The two motors are the same, the part that's different is a white plastic part in the front motor. The plastic part of the rear motor is black. This plastic parts are the Brain of the glass panels an the curtain, and can be switched from one motor to other.

Any ideas???

Well, today I´ve been working with tre roof, and stlill can´t get it working well, seems like the curtain motor doesn´t knows that the curtair is already closed, and keeps trying to close it. I´m driving crazy!!!!!

ezdanny not that i have hands on experience yet but after finally finding a part after a year im gonna work on it very soon also. i have the problem with the broken hinge/cable on the right. the only thing i can say is see the manual on properly setting up the sunroof.

if my memory isnt mistaken your suppose to initialize it after any repairs. other than that the only piece of advice i can say if that doesnt work start cleaning connectors and if not again replace the motors which can be bought instead of an entire roof.

Hi,
yes the actual motors are the same but the front has the chip in which controls the two motors. So the two assemblies are different but bare motors the same.
I had our skyroof off the car and completely stripped it to repair a damaged "bordon cable" thats the drive cable. Basically a thick wire with another wire spiraled around it, and as the motors turn a cog meshed to the spiral this is how the roof is driven.
It all very sensative to friction/dirt/lubrication. And is therefore prone to getting out of sinc. When this happens damage to the bordon (drive) cable, or gathering, bunching can occur.
Is the noise you have a clicking sound? If so this is the drive cog slipping on the cable. There is one pair of cables driven by the front motor for the glass and one pair driving the the blind driven by the rear motor.
Hope this helps.
Forgot to mention I still have a new rear motor I didn't need.

Hi there again, today I´ve being workin in the roof. I opened it manually, checking driving cables and they´re ok. I´ve made a test, manually opened the glass and the blind, but took the curtain off the guide, to eliminate all resistance. Then made the reset procedure, the glass close fine, and the blind mechanism started to close, but when reach the end of the roof, keeps closing, making the horrible clicking noise. So I think it´s the anti trap, because it seems that the blind "doesn´t know that it´s already fully closed"

Being a newcomer I think I posted my mail the wrong place (sorry Kennif). So try again here:
Could any of you experienced Stilo owners tell if new sky window cables can be purchased separately or if there are other solutions to worn out cables - other than the dealer's suggestion of a new £2000 roof frame?
many thanks in advance .

I had exactly the same problem.
The cause of the problem is that the bracket that presses the cable against the motor is deformed and permits the motor to revolve even when the blind is fully closed. When this happens a terible noise is produced but the sensor can not sense that the cable is not moving because the motor IS moving. So it keeps trying to move and make noise.
I removed the bracket, hit it with a hammer and slightly corrected the deformation. After that it worked!

Which motor are you on about? Front or rear? Also.. How do you get to the bracket?

Owen.

I'm talking about the rear motor, the one which controls the blind.
To have access to the motor, you have to remove the headliner first.
The motor is secured with 3 screws on a black metal bracket.
You remove the motor and you see that also two threaded cables go inside this
"bracket".
When the motor turns, it turns these 2 cables. One cable moves the
left side of the blind and the other one the right side of the blind.
The bracket is fixed on a big metal plate and consists of two small plates fixed together with 2 or 3 screws.
Normally the 2 plates must align perfectly together and you should not
be able to move the cables that go inside them.
In my case the upper plate was deformed.
I noticed that only after I unfixed the bracket from the big plate and the cables, saw it from the side and noticed that there was a gap between the two plates.
Soon I am going to upload some photos of the deformed bracket.
Now I have the problem of how to wind the spring of the blind.

In the big round hole the motor engages with the two threaded cables that move the two sides of the blind (left side and right side)


Notice that there is a gap between the two plates.
This gap permits the motor to keep turning even when the blind has reached the full closed position. This causes the noise that is heard in the video that ezdanny has posted (youtube.com/watch?v=XLl7k3fRVlM )

Hello again.
That piece is broken, so I thinks that´s the problem!!!!
Where can I find this part?? I wrote to Webasto and they told me that only Fiat can sell me that part, and Fiat told me that they don´t have it!!
Please Help!!!
