I have a 2003 S60 T5 that I purchased used with 35k miles.

#1) Is there any software update or anything that will make the sunroof close automatically when the car is turned off? The aftermarket sunroof on my Honda did this...surprised a luxury vehicle requires me to reach up and remember to close it every time.

#2) When I one-touch the sunroof open, it only opens 95%. If I manually hold down the switch to open it the last 5%, I get a horrible vibration/resonance. Seems like Volvo goofed in the design, and had to put in a software hack at the last moment to only open it 95% of the way. Comments? Anyone else had this happen?

 

To your second question, it sounds like something is in your track that is causing the auto back make it think it is all the way back. As I understand it, when the circut gets some feed back from the motor not being able to turn properly it kills the power (thinking its all the way back)

That would explain the stopping at 95% and the problems on the last 5% (granted this is all theory from what I know of cars so don't quote me on this)

 

As it says in the users manual the sunroof will only open 95% of the way with the first touch. For some reason Volvo calls this the 'comfort' setting. The remaining 5% will open if you hit the switch again. Yeah, Volvos are quirky.
