Never had the problem with mine guys (tjena!), while at work my car sits outside and we now got temps down to -20. I only use a pre-mixed fluid for -18 C (doesnīt freeze even though the outside temp is a bit lower). As someone mentioned above the sensor is most likely conductive, and I think the problem lies in the conductivity of the fluid; too high concentration of washer liquid or using deionized water to mix with it could probably be the contributing factors. Use normal "dirty" water if u mix yourself or buy a pre-mixed solution. Should work.
And about the rear washer not getting liquid when the warning has gone off, yes that seems to be the case every time so I think itīs meant to be that way.
