Bi-zenon issue

One of the bulbs popped on my bi-zenons. While i was waiting for some ebay replacements (£24 for 2 as opposed to £138 for one from tps) i noticed the leveling had stopped on the single working light. It did not go through the level check when the car is started up. I assumed it stopped because the bulb is out. When the new bulb was installed the warning light on the dash went out and the lights worked but it still does not self level. They are both pointing at the ground
Can anyone help me sort this. I have VDCS but not looked at it yet as at work

First thing to check is that the level sensors are not broken. They are located on the nearside (RHD) wishbones front and back. Often the lever connected to the sensor breaks.

Using VCDS you can measure the voltage from each sensor and drive the motors on the heaflights to check their operation.
