Unfavorable tolerances for the plug\-in connections of the wheel acceleration sensors may result in fault code memory entries and the VDC being deactivated. If the VDC control unit identifies an implausable value from one of the wheel acceleration sensors, the VDC will be deactivated and the driver is informed by a Check Control message. The vehicle then defaults to the conventional suspension.
- [B660416](/bulletins/10151203.md), 2018-12-10, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE. """Comfort Access Restricted"" Check Control Message is Displayed.

The DDE software application for exhaust gas recirculation control \(EGR\) does not favorably match the diesel fuel grades available in many parts of the US market. The high pressure EGR cooler could become filled with soot particulate to the point that exhaust gas flow and cooling efficiency are significantly reduced. This could result in the Service Engine Soon light coming on with EGR control / Air mass faults being stored in the DDE.
