Rear windscreen replacement

[Big_dom91]

Is there anybody who knows the cost of replacing the heated rear screen on a A6 saloon 2013, as the heater elements on the window dont work properly as some have come away and so when the heater button is pressed it takes ages to work and even then its patchy😫

You used to be able to buy a small bottle of electrical conductive paint (not sure if Halfords stock it) and you could easily repair the tracks rather than replace the whole screen
