Re: Do I believe my "Water in Diesel filter" message?
I might be wrong here, but isn't it supposed to come on (rather like all the other warning lights do) on start up? I think you need to do something if it comes on whilst you are driving not on start up.
Also FYI, mothers Punto 1.9JTD (same engine) was recently serviced by a trusted and excellent mechanic, and he didnt replace the fuel filter because he said there was no need, no water in at all.
