WARNING: This page is about a different car, the 2011 BMW 750xi, 2011 BMW 750Lxi, 2010 BMW 750xi, and 2010 BMW 750Lxi. However, it is still accessible from the selected car via links, so may be relevant.
When replacing the H.P. lines, you must carry out a venting procedure after filling the fluid reservoir.
During the venting operation, a large amount of washer fluid may emerge from the spray nozzles. Have cleaning cloths at hand.
Call up service function "Vent headlight cleaning system" by way of DIS or MoDiC (refer to BMW Diagnosis and Information System). In this case, the washer pump is activated for approx. 6 seconds and the H.P. lines are vented.
Top up washer fluid.
