Help with Suspension Settings etc

[Iyole]

Having recently acquired a S8 D2 I need some advice on the following...

1) Suspension Settings... Checked Manual etc and don't come across
any Info regarding the suspension settings.
On the Web I pick up that this can be done with Vag com....
Is this correct ???

2) Winsdscreen washer - When I got the Car the reservoir was empty.
Filled it ...... but still no water coming out of the jets....
Any advice on where to start and is this a DIY job or do I need to take it
in to the "Stealers" to have rectified.

Thanks

PS... Having an absolute ball with the Car... Really enjoying the Power
and Quattro...... Stunning Car and G8 Forum...
