Does anyone know if it's possible to fit xenon headlights to an XC70? We have 2 P3 XC70s, one with them and one without, the car with them has height sensors on the suspension and a different switch panel on the dash. The car without them has a spare plug in the front right wheel well that appears to be for the height sensor. If I remove a complete kit from an XC70 is there any programming required to make them work?
