Affected vehicles
Mercedes-Benz Citaro G 2007–2010
Hazard
In articulated buses, condensation water from the ceiling air conditioning unit accumulates on the underside of the ceiling panel and repeatedly drips onto the distribution panel. This can cause electrical circuits within the distribution panel to corrode and short circuit, resulting in erroneous warning light illumination and potentially leading to fire.

Remedy
Install a plastic water-protection cover on top of the distribution panel in all vehicles.
