Been doing lots of research into this, found some VW official springs, they go by the name of Driver Gear springs and are made by eibach for volkswagens, along with the VWR springs which are also eibach.
drops are:
VWR: 20mm
DG: 10mm
Both great springs, I don't know which ones I should try!
Leaning to the VWR springs, as apparently they have been sold to 1000 DDC/ACC customers and they have been developed and tested to be fine with the DDC/ACC system, this makes me feel better!
