A5 Sportback Rear Windscreen Demister Issue


Registered User
Hi everyone,

I’m having a recurring problem with a rear windscreen on an A5 sportback s-line (19 plate). This has been a great car but I’m wondering if there is a design issue. The car had its seals replaced by Audi and yet again I’m getting build up of condensation inside the rear windscreen and the demister is no longer functioning. It’s going back in for second diagnostic/repair.

Is anyone else experiencing this issue?

Tbh as its under warranty, I'd just moan at them to fix it properly, could be seals, glass, supply, sealant variety of things tbh, however as its free to do warranty way, leave to them.
