What’s wrong
The Safety Recall relates to the air-conditioning wiring harness located behind the dashboard. On the affected vehicles the wiring harness was fixed very close to a screw connection on the interior microfilter housing cover. The microfilter of the air conditioning system will be regularly replaced as part of the oil service. It cannot be ruled out that cables may be damaged when replacing the microfilter during a workshop visit. The filter cover has to be removed from the lower part of the instrument panel. After replacing the filter the cover has to be refitted at which point the wires may become damaged or trapped. If the wiring harness is damaged this could lead to malfunctions of the air conditioning system as well as to a short circuit. In case of a short circuit a sensor may overheat while the vehicle is in operation. As a result smoke may develop from the instrument panel and subsequently a fire cannot be ruled out.
The fix
On the affected vehicles the air-conditioning wiring harness will be checked repaired if necessary and re-secured in a modified fixing.
