    Allroad Static Conversion Xenon Headlight Issue

    Guest-only advertisement. Register or Log In now!
    I have swapped to coilovers on my allroad. I have unplugged the level control computer but since then the xenon head lights do not adjust when turning on the car and I cannot communicate with the Xenon range control computer (55).

    I think with the allroad the Xenon ECU receives power from the level control computer. Does this sound right, do I need to jump power from the level harness to the xenon ecu? I have been going over the wiring diagrams and cant seem to find much about this.

    Correct, jump power at the plug you unplugged from level control module, paper clip works very well but wrap it in insulation tape afterwards.

    "- when removing air suspension computer, you need to forward one pin from the harness to another one to power up Xenon module, paper clip works well here with some electrical tape wrap around it. You will have to retain left front and rear sensors for XEnon module to auto level lights:

    50 pin, the larger plug at level control computer.

    Black power wire pin 49 (terminal 15 of ignition switch) to yellow/red pin 17 (xenon leveling +12V power supply)"

    Julex, thank you. I had figured out that red/yellow pin 17 was the pin that needed 12. Was currently searching for way to get it switched power.

    Also, I have noticed since I removed the level computer that my rear hatch doesn't unlock...weird...

    All is well now with the Xenon ecu. Thanks!

    (I also figured out my latch problem, and it was not related to removing the level computer...lol)
