    Car was shuddering when idling and acting a bit odd at other times.
    The service people found that the cause was water contamination of the
    fuel. Quite expensive to fix - replacing fuel filter and removing tank
    so all fuel could be purged.

    No recent posts on this topic but I found an old 405 one about the
    "water in fuel' light coming on (which, apparently, meant that the
    fuel filter needed draining).

    No warning lights were triggered by my problem.

    What would bother me is that there's no mention of what they've done to
    prevent further water ingress. It got in before, it will get in again. The
    usual (but not the only) suspect would be the seal around the filler cap.
    Another issue is that it's not just the water that's a problem, bacteria
    breed in the water and create MGS.

    I'm not familiar with the 407, does it have the light you mention?

    And does the filter have a capability for draining water? Not usual in cars
    rather than trucks I know. There may be a case for changing the filter
    between services as a preventative measure.

    Of course the water could have been put in with the fuel. It wouldn't be
    the first time that a filling station let its tank get too low and the water
    that has separated out at the bottom got mixed into the new fuel. We had a
    spate of it around here a few years ago. Can't remember which station it
    was but it was one of the supermarket chains. If this is the case, and you
    can identify the station, if other people have had the same problem you
    should be able to claim compensation.

    Yes, or a car's tank filled just after the gas station's refilling.

    There may be a plage of water in fuel here in the next weeks.

    The only way the water could have got in is with the last fuel refill.
    I plan to pursue the matter and will report results.

    This another example of 'progress'. Fuel tanks once had a drain plug
    in the bottom. Up to my 505 I understood virtually every element of my
    vehicle. No longer. On the other hand they do seem to get more trouble-
    free (fingers crossed!)

    Ah, that $A500 means you're in upside-downia, right? I was assuming you were
    in UK where we have had biblical quantities of rain and snow of late.

    Assuming it's been fairly dry for you, then the water is indeed likely to
    have got in during refilling. But that brings another point. For water to
    have been in the fuel in sufficient quantity to do this[1], there must also
    have been many other cases of problems after refuelling at this filling
    station. Have you heard of any? Anything in the local press? Does your
    garage know of other cases?

    If you try to pursue the matter and there's only one case, they're going to
    say it's your car, not their fuel.

    [1] Because there are several traps and filters which would all have to be
    full of water before any could get in your tank, assuming a reasonably
    modern system.
