BMW 8 Series Washer Jets Fail Due to Heat Damage

Hey there! Had the exact same issue with my 2020 BMW 6 diesel at 45,000 km. The washer heater connection was faulty, causing intermittent failures and error codes. My washer nozzles were getting blocked and showed signs of heat stress too. Got it checked at the garage last month. The main culprit was a damaged cable harness connected to the washer heater system. The connections had corroded and were causing the heater to malfunction. The mechanic had to replace the entire washer heater unit and rewire the connections. It wasn't a huge mechanical issue, but it needed immediate attention to prevent further damage to the nozzles and heating system. The problem hasn't returned since the repair. Would definitely recommend getting it checked by a certified BMW technician, as they'll have the right diagnostic tools to confirm if it's the same issue. Best regards

Thanks for sharing your experience! Glad to hear you got it sorted out. I'm dealing with very similar symptoms right now, especially with those nozzle blockages. Would you mind letting me know roughly how much the repair cost you? Also, just curious if you've had any other little quirks pop up since they fixed it? Really appreciate the help!

Hey again! Yeah, happy to share more details! I actually just had this fixed a couple weeks ago, the total came to 95 € for the repair. It turned out to be exactly what I thought, just a faulty cable connection to the washer heater that needed sorting out. Much simpler than I initially feared! And you'll be glad to hear everything's working perfectly now. The washer system's been running like a charm since the fix, no more blockages or error messages at all. The nozzles are spraying properly even in cold weather, which is such a relief. It's honestly one of those repairs that seems scary at first but ends up being pretty straightforward once you get the right mechanic looking at it. I was lucky my mechanic spotted the issue quickly and didn't try to upsell me on unnecessary parts. Let me know how yours turns out, hope you get it sorted just as easily as I did! Take care!

Thanks so much for all the detailed info! You've actually helped me make up my mind about getting it fixed. I bit the bullet and took it to a certified BMW workshop yesterday, turns out it was exactly the same issue you described. The mechanic found the damaged cable harness and replaced the washer heater unit. The total bill came to a bit more than yours at 110 €, but I'm just relieved it's sorted now. The nozzles are working perfectly again, and no more error codes popping up on the dashboard. Definitely worth getting it done properly rather than letting it get worse. Really appreciate you sharing your experience, it gave me the confidence to get it checked out instead of putting it off. Sometimes these small issues can seem more daunting than they really are! Thanks again for all your help. Take care!
