My Peugeot 806 doesn't have a water in fuel sensor, which is a bit of an oversite given that the tiniest amount of water will destroy £1000 worth of injectors.

However it looks like all of the wiring is there already, and the fuel filter is the same as that used on a 406 which does have the option of a water in fuel sensor...

Therefore I bought a 406 water in fuel sensor.

It looks as though it might be useful for other cars too. All of the electronics seems to be integrated into the sensor. It just has three connections: 0V, +12V (switched) and bulb.

The thread on it looks like M12 x 1.5mm, though the o ring is what actually seals it.

It looks like it uses some sort of resistivity difference between water and diesel to work.





I will post more when it is installed and hopefully working.

But Philip, have you *ever* needed a sensor up to now?

That just screws in place of the drain screw, doesn't it?

BTW, the Suzuki scantool doesn't do what you were looking for
