Does anybody know if the Q5 main screen washer jets are heated? ~ if yes how do you turn them on?

Yesterday in sub zero temps my washer jets completely froze ~ The headlight washers still worked so the fluid hadn't frozen......!

Thanks,

Lee.

i reckon that its because the headlight jets are covered by the plastic cover that opens and are kept warm by the super hot engine!

thats my ten pence worth lol.

I believe that the screen washer jets on the Q5?s are actually heated. If you notice the ?tubes? going to the jets are fabric-wrapped. I think this wrapping covers both the inner plastic tube carrying the washer fluid and also a wire which carries the power to the heating element.

As far as I am aware there is no manual control (switch) for the heating of the jets. I assume there is some form of automatic thermostat which turns the heating on when the ambient temperature drops below a certain threshold.

Unfortunately the current harsh winter conditions in the UK coupled with wind-chill cooling could result in the fluid in the tubes leading up to the jets freezing unless quite a high concentration of washer fluid additive is used. I agree that the front headlight washers are probably partially insulated behind the plastic covers.

I recall that Audi also recommend the use of a screen-washer / de-ionised water mixture. This is to avoid calcination within the heated jets (aka furring up within a kettle) if hard tap water is used.

Agree you really need a high concentration of stuff in the washer bottle as it's probably the pinhole nozzle that's freezing

Good news.

I keep topping mine up with neat screen wash at the moment.
