Post by om2 »

Hi All!
I am new to Xantia world, so excuse me if it is obvious question.

And Haynes guide, don't answer this question.

Well, looking in my 94 td sx manual, the nearest thing is the low level screenwash warning. This is situated in the top right of the right hand bank of warning lights.

Correct, water in fuel, open drain cock on filter and pump rubber bulb to expel any water, catch the discharge (don't let it run down into the bellhousing and contaminate the clutch) and examine it for water.
If warning light persists, sensor inside filter may require cleaning, if so, unscrew it and use a plastic scouring pad lightly to clean it.

Dave,
I must admit, I did initally think it looked like a "water" type indicator. And I was thinking along the lines of water in the fuel ( or in the case of some garrages, fuel in the water <img src=icon_smile_big.gif border=0 align=middle>).
However, there is no mention of such an indicator at all in the manual ( I would have expected one anyway ! ).

Thats right Matt, no mention of it, wether its an oversight or a deliberate omission who knows.

The feature is however discontinued on later models, perhaps it was omitted because they were going to dispence with it anyway.
Important to buy diesel fuel from filling stations where the stock changes rapidly, the problem is then unlikely to arise.
Diesel fuel can contain more that just water as contaminants, microbes that feed on the hydrocarbons can infest fuel tanks and create a thick sludge, damaging precision fueling equipment, though rare in road going vehicles it is a major concern in marine aplications.

Cheers Dave!!
That has answered a question of mine too! I wondered why, after draining the fuel filter on my dads Xantia SX/TD more than once, the water in fuel warning lamp was lighting up now and again. I knew there was something wrong, now i know what.
Thanks guys<img src=icon_smile_big.gif border=0 align=middle><img src=icon_smile_big.gif border=0 align=middle>Regards, Rich.

Dave Burns, I believe the Microbes you spoke of are called Cladisporium Resanae, or something like that. They are a large problem in aircraft fuel tanks as well, they feed on the HC's in the fuel at the water/fuel boundary and there poop, for want of a better word, is the corrosive sludge you spoke of. The microbe is carried in the sea water that is used to pump the oil from the sea bed. When the oil is the fractionally distillated, in the manufacturing of the fuel, some of those microbes are carried in the evaporating water and find themselves mixed with the fuel. When the fuel is allowed to settle for long periods all the suspended water molecules make their way to the bottom of the storage tank, if garages don't drain this tank water, you can get an increased quantity of water in your fuel. As Dave B said, buy from garages with a rapid turnover of stock.

What a fantastic web site! You learn something new every day! (w.r.t. Cladisporium Resanae), I hope the Raps Methyl Ester (RME) I drive on is immune to these little buggers!
