    Water in fuel

    Hi guys

    Water in fuel warning light came on the other day. I drained the filter and there was no water in there. Light when out, but has come on again a few days later. 2011 2.7 D4.

    Any suggestions? Is there some sort of connector that might be corroded/wet?

    Cheers
    Lucas

    Sensor connector on filter housing could be the culprit.

    Mine had flaking insulation near the plug which was causing the same thing. Bare wire is not the best!

    Often happens after the coolant system has been flushed.
    Faulty float in coolant bottle the usual culprit.

    If you read the code is is most likely water in fuel - sensor fault. There have been a few cases of this. The fault codes differentiate between the sensor fault and actual water in fuel but warning light comes on for both.

    Can someone explain this to me? Why are people replacing the entire assembly when the comments indicate the sensor is at fault? The sensor screws into the bottom of the fuel filter, so surely you only need to replace the sensor itself? Maybe I'm misunderstanding the issue. I ask this as I intermittently have this error and it typically goes away in a day or two.

    From my Iidtool, I got this error:

    P2269-68 (2D) Unknown

    I will replace the sensor +/- the whole assembly as there is no water in there.

    It's not the actual sensor in the filter but the sensor module that is mounted on the housing.
