Audi S8 Frozen Wiper Jets: Heater Element Fix Tips

Had the same problem on my 2016 Audi S6 last winter. Traced it to a faulty connection in the washer heater system and a blown fuse in the secondary fuse box. The heating element connectors were corroded, causing intermittent windshield heater operation during winter driving. The repair involved: Testing the washer heater circuit, Replacing the corroded wiring connector, Installing a new heating element assembly, Replacing the 15A fuse, Resetting the error codes The heater malfunction was serious enough to require immediate attention since frozen washer nozzles create significant safety risks in winter conditions. The entire system needed testing as corrosion can spread through connected components. Main signs to look for: Error codes specifically related to washer system, Inconsistent spray patterns, Complete failure during freezing temperatures, Warning lights on dashboard Worth checking the fuse first, its the simplest fix. If thats not it, you likely need professional diagnosis as accessing the heating element requires partial removal of the windshield cowl assembly.

Thanks for sharing your experience. The symptoms sound identical to what I dealt with on my S8. The frozen washer nozzles and windshield heater malfunction were seriously impacting winter driving. Quick question, do you remember roughly what the repair cost you? Also wondering if youve had any other washer fluid system issues since getting it fixed. Might help me gauge if I should prepare for any follow-up repairs too.

Glad to share an update. After getting the repair done, my washer fluid system has been working flawlessly through the cold season. The windshield washer heater issue turned out to be simpler than expected, just a loose cable connection that had worked its way free over time. The repair cost came to 95 Euro, which included diagnostic time and fixing the faulty connection. The washer motor and heating element themselves were actually in good condition, which kept the cost down significantly. Since the fix, I havent experienced any more problems with frozen nozzles or heating element malfunctions during winter driving. The washer fluid flows perfectly now, even in freezing temperatures. Make sure your mechanic thoroughly checks the cable connections before replacing any major components. A proper inspection can save you from unnecessary parts replacement. In my case, what seemed like a complex washer heater failure was resolved with a straightforward connector repair.

Finally went to get this fixed last week. What a relief, turns out my issue was more involved than a loose connection. The mechanic found the windshield heater completely failed and the washer fluid lines were damaged from repeated freezing. Total repair came to 450 Euro including: New heating element installation, Washer fluid line replacement, System diagnostic, Fresh washer fluid fill Not cheap, but worth every cent. The windshield wipers work perfectly now, even in freezing conditions. No more error codes or frozen nozzles. Really glad I asked here first, helped me understand what to expect and avoid getting overcharged. Pro tip for others: Consider getting the washer heater system checked before winter hits. Much easier to fix these issues preventively than deal with frozen lines mid-season.
