Water in Diesel Warning Light???? 205

morning....
...I'm new to diesels and have been running a 1993 205 1.8 STDT for the
last 6 months. I had the fuel filter changed at 82,000 and I have now
done 95,000. This morning a new warning light came on which I found out
was the water in diesel light and in the handbook it says that it means
there is water in the fuel filter and to get it purged as soon as
possible. Do I have to get a new fuel filter? what is involved in
purging the existing?
...any help would be much appreciated, does it matter if I drive for
another 50 miles as it is?
thanks
tim

 

FOR THE PRICE OF A FILTER ITS WORTH REPLACEING.SO REPLACE IT AS SOON AS
POSS.

 

This is one of the more unreliable sensors that PSA use, many people just
disconnect the sensor on the fuel filter. But assuming that unusually it is
correct, then you might have some fuel at the bottom of the filter bowl. All
you really need to do is drain the filter bowl (there should be a drain off
point at the bottom somewhere, with a small pipe attached which goes down
past the engine. Put something under this to catch the fuel and see if there
is indeed any water there. Then you have to prime the system again and make
sure you have got all the air out. You can change the filter element if you
feel you should. However, if no water comes out of the filter, than you can
assume it is a false alarm, so no point in worrying about the filter
element.

 

My 205D does it all the time. No water visible. I think it's just
exercising the light so I ignore it.
