3401132018-11-26. Service bulletin. SERVICE BRAKES. MErroneous "Service due" Message Though Brake Lining Thickness Sufficient. The CBS data calculated for the remaining distance of the front and/or rear brake pads does not agree with the actual brake pad thickness. The yellow brake lining service due indicator illuminates even though the pad thickness is greater than the minimum wear limit (approximately 3.7 mm); the brake wear sensor has not yet been activated (from a thickness of approx. 4.2 mm). In some cases, the red warning message may already be active. The CBS front/rear brake display is based on a mathematical calculation. Various influences are incorporated into this calculation (for example, vehicle speed, brake pressure, and rotor temperature). Due to changing driving characteristics and/or unfavorable environmental conditions, the calculated remaining distance may differ from actual pad thickness.

After performing extensive engine repairs (e.g., cylinder head removal), the engine begins to knock and may lose power. Debris has entered the engine oiling passages during cleaning of the engine block and cylinder head mating surfaces during engine repair.
0703142018-11-26. Service bulletin. EQUIPMENT. Diagnosing Stored Fault Codes to Help Avoid Repeat Repair Visits. Analysis of FASTA data and repeat repair visit reports indicates that there are many fault codes that are stored in the above vehicles, but they are not diagnosed to identify their root cause. Fault codes that are not diagnosed to find their root cause can lead to a repeat repair visit to the workshop by the customer. Where diagnosis (vehicle or short test) with ISTA has already started, it is important to diagnose the fault code(s) listed below (when they are stored in the vehicle) during the current workshop visit. This will help lead to a reduction in workshop repeat repair visits and higher customer satisfaction.
