ALP 4 Inefficient windscreen demisting
NOTESOnly consult this customer complaint after a complete check with the diagnostic 
tool.
Special notes:
Check that the inside of the windows are not greasy, as this lowers the efficiency of 
the demister.
Use the diagnostic tool to check that the computer is correctly configured by reading the LC046 
GEOGRAPHICAL ZONE configuration. If necessary, reconfigure the computer (CF024 GEOGRAPHICAL 
ZONE) and check that the windscreen demisting operates correctly.
Check that the air extraction vents are not blocked. 
Repair if necessary.
Is the fault still present?
YES
Check that there is no water leakage in the 
passenger compartment which would significantly 
increase the humidity and reduce the efficiency of 
the demisting. Repair if necessary (see ALP12 
Water in the passenger compartment).
