which measures the water content in the fuel filter.
A warning lamp (near the instrument cluster) comes on if the accumulated amount of water
exceeds a certain value.
Please refer to the current service literature for details of how to drain the water from the
fuel filter.
A temperature-dependent control valve is integrated in the return part of the fuel filter.
The control valve is a ball valve controlled by a bi-metal strip. When the fuel heats up, the
bi-metal closes the return to the filter progressively, so that at temperatures above 50 °C
only a very small amount of fuel can get to the fuel filter.
The feed and return fuel lines are colour coded: feed white, return red.
