BMW iX1 Washer Nozzles Freezing: Fix & Cost Guide

Let me share my experience with a similar issue on my 2020 BMW iX3. Had the exact same symptoms with the washer nozzles last winter. The error code turned out to be related to a faulty connection in the washer heater wiring harness. The cable insulation had worn out near the connector, causing intermittent failures and those burnt marks you mentioned. Got it fixed at my usual garage. The job required replacing the entire washer heater assembly and rewiring the connections. It was actually a serious safety concern since the malfunctioning system could've caused a short circuit. Plus, driving without proper visibility isn't safe. The repair wasn't too complex, but they had to remove some components to access the wiring. Took about 3 hours to complete. Since it's the same system across several BMW electric models, you'll likely need a similar fix. Don't wait too long, those burnt marks suggest it's already causing damage. I'd definitely get it checked soon, as this type of electrical issue tends to get worse over time.

Thanks for sharing your experience! That sounds very similar to what I'm dealing with. Good to know about the wiring harness being the culprit. Do you remember roughly how much you paid for the repair? Also, has everything been working fine since the fix, or have you noticed any other issues popping up?

Hey there! Just wanted to follow up, yes, everything has been working perfectly since I got it fixed. I actually just had it repaired last week and I'm glad you asked about the cost. It ended up being 95 € to fix a faulty cable connection in the washer heater system. Much simpler than I initially thought it would be! The nozzles are working great now, no more freezing or burning issues. The error code is completely gone too. Honestly, I was expecting it to be more expensive, so I was pretty relieved. My mechanic showed me that it was just a damaged plug connection that needed sorting out, nothing too major like I originally feared when I first replied to your post. If you're seeing the same symptoms I did, it's probably the same issue. I'd say go ahead and get it checked, it's a relatively straightforward fix and totally worth it for peace of mind. Plus, being able to actually use your washers properly in cold weather is pretty important!

Thanks for the update! I actually went ahead and got mine fixed yesterday after seeing your first response. You're right, it was a pretty straightforward repair. My mechanic found the same issue with the wiring connection, though mine cost a bit more at 120 € since they had to replace a few extra bits that had gotten damaged. Really glad I didn't put it off any longer. The burnt marks on my nozzles were apparently just starting to affect the surrounding components. The repair took about two hours, and now everything's working perfectly. The washer spray is much better, and that annoying error code is finally gone. Funny enough, my mechanic turned out to be much more professional than the last one I'd dealt with. They even showed me the faulty parts and explained what went wrong. Definitely feeling better about the whole situation now. Thanks again for helping me make the decision to get it checked out!
