Erroneous "Service due" Message Although Brake Lining Thickness is Above Minimum Specification. The yellow "Service Due" warning message lights up in the instrument cluster, even though the brake pad thickness is more than 4.2mm (above the thickness at which the pad sensor intervenes). The calculated remaining service life for the brake pads (front and/or rear axle) from the CBS data does not match the actual brake pad thickness. Software calculation of the brake pad wear model in the DSC.
