BMW i8 Washer Nozzles Freeze in Cold: Common Fix Inside

Hey there! I can relate to your washer system troubles. I have a 2018 BMW i3s Hybrid and faced similar issues last winter. Had the same symptoms, washer nozzles acting up and error codes popping up. Took it to a certified shop where they diagnosed it as a faulty connection between the washer heater control module and the main wiring harness. There was corrosion building up in the connector, which was causing intermittent failures. The fix wasn't too complex, but it did require some specific BMW diagnostic tools to properly reset the system after repairs. They had to replace the connector and clean up the wiring harness. This wasn't a major repair, but leaving it unfixed could've led to bigger problems with the electrical system. My advice, don't wait too long to get it checked. These washer heater issues can get worse in cold weather and potentially affect other connected systems. Make sure to find a shop that's familiar with BMW hybrids, particularly the i-series models. Hope this helps with your decision!

Thanks for sharing your experience! That's really helpful info about the connector and wiring harness issue. I'm curious, do you remember roughly how much you ended up paying for the repair? Also, has everything been working smoothly since then? My i8 is still having some other quirks and I want to make sure I'm not missing anything when I take it in.

Hey again! Glad I could help with my previous reply. Yes, I actually just got it fixed last week and everything's working perfectly now! The mechanic confirmed it was indeed the faulty windshield washer heater, pretty much exactly what I suspected based on the symptoms. The total bill came to 95 € for fixing the cable and plug connection that had gone bad. The repair itself was straightforward once they identified the problem. Since getting it fixed, the washer system's been working like a charm, even in the cold weather we've been having lately. No more error codes popping up either, which is a relief! Regarding those other quirks you mentioned, might be worth having them check those out while they're at it. These i-series cars can have some interesting electrical gremlins sometimes, but they're usually not too serious if caught early. My i3s hasn't given me any other trouble since the repair, which is pretty encouraging. Let me know how it goes with your i8 when you get it checked out!

Thanks so much for following up! I bit the bullet and took it to a mechanic yesterday. You were right about catching things early, turns out my issue was pretty similar to yours. The washer heater system had a damaged connection, but they also found some wear in the nearby wiring that needed attention. Repair cost was a bit higher than yours since they had to replace more parts, but honestly, I'm just glad it's fixed now. The washer system is working perfectly, and that annoying error code is finally gone! Really appreciate you sharing your experience, it gave me the push I needed to get it sorted before winter hits hard. Funny enough, while they were fixing it, they also spotted and fixed a small issue with the door sensor that I hadn't even noticed. Sometimes these things work out for the best, right? Now I just need to keep up with regular maintenance and hope no other surprises pop up!
