have the fault below along with the headlight symbol on the dis.


Address 55 -------------------------------------------------------
Controller: 4B0 907 357 B
Component: dynamische LWR D02
Coding: 00020
Shop #: WSC 02335
1 Fault Found:
00776 - Level Control System Sensor: Left Front (G78)
31-00 - Open or Short to Ground

This I believed to be the sensor, so purchased one from Audi, as a test I plugged it in without connecting it up to the suspension to see if this cleared the problem on the dis, it didnt. I measured the voltage going to the sensor - there are 3 wires - one ground, one +12v and the other i believe is the sensor going to the controller.

Where is the xenon level controller located, I need to check the connectivity at the module. Thanks in advance.
Ian.
