CAUSE A non-approved washer fluid is used (fluids that contain a silicone additive, normally colored other than blue). INFORMATION The washer fluid level sensor is a contactless capacitive sensor. The sensor sends a low fluid level signal to the gateway module (FEM - Front Electronics Module or BDC - Body Domain Controller) which in turn displays a low washer fluid warning in the instrument cluster. The use of a ""non-approved"" washer fluid (silicone-based fluid) can cause the low fluid warning light to come on even when the reservoir is full.
