Hi! The xenon I can make a 'how to giude'.
The alarm: The alarm unit placed in the bodycomp. My BC shows me that it has the alarm function but it is just disabled. I also got al the loom. The bonnet switch cable, the sensor cables and the siren cable to. I switched it to enabled and did a proxy, my friend gave mi his alarm sensor panel. I had armed and close the car. The dash warned that the bonnet is open (i didnt have the switch yet). When i get into the car the dash shows me that 'Attention break-in' so everything work fine.
I will make some instrument bought and built the original parking sensors because i had the loom for it. Now I'm going to buy the memory seats with the mirrors and gonna build in. Also i'm going to change the front window and buy the rain sensor+the lamp&wiper and the 500 autodimming mirror (for the rain-dusk sensor i have the loom).
I'm going to write a little blog for all the changes I've made. My motto is: I love the factory status.
