Doc take your passenger mirror out and check the part number on the round motor? if it ends in a C then you have the kerb mirror dip function it just needs setting up with VCDS, none of this needing memory seats or folding mirrors anymore.
I fitted the motor and loom to my car and then fitted the mk6 door controller, with a bit of wire swapping I now have the kirb dip - plus folding mirrors with auto dimming and puddle lights.
