BMW X6 Washer Nozzles Freezing: DIY Diagnosis Guide

Hey there! I can relate to this issue since I experienced something similar with my 2011 BMW X5 35i. Last winter, my washer nozzles were acting up the same way. Took it to my trusted mechanic who found that the heating element wiring had deteriorated, causing intermittent connections. The connector plug was also corroded. The fix involved replacing the entire washer heater assembly and the wiring harness. It wasn't a major repair in terms of complexity, but it was important to fix because frozen nozzles can crack and cause bigger problems down the line. Make sure your mechanic checks both the heater element and the wiring/connections, in my case, just replacing the heater wouldn't have solved the issue completely. They'll need to scan for the specific error code to confirm, but these symptoms match what I experienced. Hope this helps with your decision.

Hey, thanks for sharing your experience! I had pretty much the exact same issue with my X6. A skilled mechanic fixed it with the heater assembly and wiring replacement, just like in your case. Can't remember how much I paid though, do you recall what the repair cost you? Also, has everything been working fine since the fix? Just wondering if any other related issues popped up afterward.

Hey again! Happy to give you an update! Just got my X5 back from the mechanic last week actually. The washer heater is working perfectly now, no more frozen nozzles even in the coldest weather. The total bill came to 95 € for fixing the faulty cable connection. Turned out it was just a damaged plug connection to the heater component, so I got lucky there. Could have been worse if they'd needed to replace the entire assembly like I initially thought. Been using it daily since the repair and everything's working like a charm. No other issues have shown up, the washer fluid sprays evenly and the heater kicks in just like it should. My mechanic did a great job finding the actual problem rather than just replacing parts. Honestly, it was worth every penny to get it fixed properly. These BMWs really need someone who knows what they're doing when it comes to electrical issues like this. Glad to hear you got yours sorted too!

Thanks for the update! Just got back from my mechanic today actually. What a relief, turns out my repair was pretty straightforward too. The washer system's working perfectly now. My fix was a bit pricier since they had to replace both the heater unit and some wiring. The mechanic showed me the old parts, they were totally burnt out. No wonder it wasn't working! Really happy I decided to get it checked out instead of waiting for bigger problems. The whole thing took about an hour and a half. Mechanic was super professional, explained everything clearly, and even cleaned up the connectors while they were at it. Such a different experience from my last garage visit! Anyway, thanks again for your help. Really appreciate you sharing your experience, helped me feel more confident about getting it fixed properly this time.
