Hello all,
I am having trouble with my panoramic roof.

As you may know, the roof opens in two stages, first the sun shade opens second the glass roof opens. The roof then closes in the opposite manner.

On my roof:
1. the sun shade opens fine by pulling either back or down on the multi-function roof switch.
2. the glass roof opens a few inches each time you press the switch back or down (it does open fully)
3. the glass roof closes in the same way (a little at a time)
4. the sun shade then will not close when the switch is pressed in any way. Instead, the motor makes a loud clicking/grinding sound.

The only solution is to close the sunshade manualy using the hand crank. Note: if I close the shade just a little bit with the crank it will then close smoothly with the motor by depressing the multi function switch forward.

Thank you in advance for any help that you can offer.

Please note that I have tried the reset instructions contained in the manual to no avail. Unless I have done something wrong, that has not worked.

Again thank you.

 

i will recomend to do a service to your roof, and then you should reprogram the roof system

 

What do you mean my reprogram the roof system ? can we do such a thing ? Where and how do we program ?

 

the program proces is in your owners manual, I had the same problem but with the roof not the shades, it is important that you lubricate all the system

 

I followed the reset process so I'm somewhat sure thats not the problem.

I will lubricate the system.
I would like to know what type of lubricant should I use and where should I apply it.

Thanks again

 

It sounds like a plastic tooth on the gear for the sunshade has snapped off.
Lets hope its something simpe.
I had difficulties with my coupe roof once and used the manual key in the drivers door keyhole to open and close the roof, sunshade and both windows. There is a chance the re-synch is out of whack and the open gear is simply rotating too far and not re-engaging.
Might be worth trying.
I've used white lithium grease on the tracks and anywhere where wear is obvious when the roof is open. I have applied the grease very thinly and lightly and the roof seems to glide smoothly with no jerking. Don't forget to apply some where the separate small glass portion tilts up as a windbreak. It tends to operate stiffly without grease.
Good luck.
