Sunroof tilts but wont open

The sunroof on my 2003 Euro Lux, tilts but wont open. However if I manually open the glass, I can close it if I press the close button. As a first resort, I would like to check if my problem is a faulty sunroof switch (the one next to the VSA switch) but can't find any info on its pinouts. The service manual I have on CD is for supposed to be for the Euro but the info it has is for a 7 connector pins so does not match the 6 pin connector for my Euro.

Does anyone have the correct switch pin out info with test information?

many thanks
