Macan's Heated Windshield Failure: Fix & Mechanic Tips

Hey there! I had a similar issue with my 2020 Porsche Cayenne (base model, 3.0L gas). The heated windshield stopped working last winter and showed an error message. Turned out the heating element had a break in the circuit – pretty common issue actually. I took it to the official Porsche service center because these heating elements are integrated into the windshield itself. Had to get the entire windshield replaced because you can't repair just the heating element. It wasn't a critical safety issue, but definitely annoying during winter months. The job took about half a day at the dealership. You really want someone who knows Porsches for this kind of work, as they need to properly calibrate the rain sensors and other electronics after installation. Would recommend sticking with a certified Porsche technician for this one. Good luck with the fix!

Thanks for sharing your experience! That's really helpful. Seems like I'll have to go through the same process with my Macan. Do you remember roughly how much you ended up paying for the whole windshield replacement? And has everything been working fine since then, or did you run into any other issues?

Hey again! Great news, I can actually give you a better update now! After my initial post, I took my Cayenne back to the Porsche service center, and they found a way to fix the heating element without replacing the entire windshield. The total came to 585€, which was way better than what I was expecting after thinking I needed a full windshield replacement. The best part? Everything's been working perfectly since the repair. The windscreen heating is back to its full functionality, no more foggy mornings or icy windshield issues. Honestly, it's such a relief, especially now that winter's approaching. The techs did a fantastic job, and I haven't had a single problem with it since. Just a heads up though, every case might be different, so your Macan might need something else. But definitely worth getting it checked out by a proper Porsche technician rather than guessing what's wrong. They really know their stuff when it comes to these specific issues. Let me know how it goes with yours!

Update on my Macan situation! Just got back from the Porsche service center today. You guys were right about going to the official dealer, totally worth it! Turned out my issue was similar but not identical to yours. They found a faulty connection in the heating system that was causing the error code. Only cost me 395€ to fix, which was a massive relief after dreading a full windshield replacement! The whole process took about 4 hours. The mechanic was super professional and even showed me exactly what was wrong. Honestly, I'm kicking myself for even considering going back to my old sketchy mechanic. The heated windshield is working perfectly now, tested it right away! Thanks everyone for the advice! Sometimes paying a bit more for proper service really does save money in the long run. Can finally enjoy those early morning drives without worrying about foggy windows!
