My car is just back from having a new water pump and turbo heat shields fitted. When out last night, I thought the left hand main beam was a bit low. Checked the headlight level adjustment by turning the light switch on and then turning the ignition on and the left hand one is not moving. The connections to the front and rear level sensor appear fine. There are no faults logged on PIWIS. Am I looking at a new drive motor for the headlight level adjustment?
 
You should be able to check the motor in Drive Links in the HBA module on PIWIS. If one isn't moving up and down as you activate it, I would check the connector on the headlamp tray first, before splashing out on a new motor.
 
Checked the connector and all the connections are sound and clean. Cleaned up the earth on the Litronic control module too. Will try with the PIWIS tonight when I can see the light move if it does.
 
Using Drive Links in the HBA module of PIWIS, I got the right headlight to move up and down but not the left so it looks like a new "Electric motor headlight levelling system" 996 631 135 00 ?
