When empty, a valve located at the bottom of the KC195 filter is free to move up and down within a cage.

This valve is designed for water drainage and location of the water sensor.

However, MAHLE said that “the valve can be heard moving in the longitudinal direction and to a small degree, laterally.

“It is possible that the retaining ring at the top of the cage could become damaged in transit and dislodged.

“This will result in a large amount of rattling, in both lateral and longitudinal directions.

The retaining ring can become dislodged.

“With the valve dislodged, operation of the water drain and installation of the sensor may be impaired.

“The filter may also become noisy during the operation of the fuel system.”

If you are concerned about the amount of rattling in the lateral direction, MAHLE say it is possible to check the valve is still located by inspecting the drain port on the bottom of the filter.

The white valve should be visible if correctly located.
