Hi RY4NTT
I try to replay here because im not able to replay directly to you.
About Xenon headlam .
Caddy is like little brother Touran.
Most of items are compatibile.
Washer system - fortunatelly bumper have housing for this from inside and all is compatibile from Touran but up to 2006. Only have to buy sprawy cup (cover) on the bumper
Washer pump - tank with fluid have space for additional pump, just to drill hole and install pump.
Washer sensor level - tank have also mark when is shoul be. This same - drill hole, install new wire, pull this stright a way to instrument cluster, recode cluster - easy

Autoleveling - most complicate. Front suspension is copy from Touran - easy to install, but rear is complicate. I made longer arm, because all reare suspencion working toogether and with org lenght or arm senspor lamp was wery sensitive. So - now arm is longer and when suspenction is moving, arm is moving much less.
