61 71... Procedure For Replacing High-Pressure Lines
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 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.
