BMW i8 AC System Dead: Hybrid Expert Help Needed

I had a similar issue with my 2018 BMW i3 Hybrid last summer. Based on those symptoms, it sounds exactly like what I experienced, faulty valves in the AC system. Had it checked at a certified BMW service center, since hybrid systems are quite complex. In my case, they found two defective expansion valves that were completely blocked, plus the AC compressor wasn't engaging at all. The valves had corroded over time which is apparently pretty common in these models. This isn't a DIY fix, it needs specialized diagnostic equipment and expertise with hybrid cooling systems. The repair was fairly extensive since they had to partially disassemble the dash to access some components. Not something I'd trust to a regular shop without BMW hybrid experience. Worth noting this was a serious issue that needed immediate attention since it could affect the hybrid system cooling as well. Would strongly recommend getting it checked at a certified BMW service center, especially given your mileage. Don't wait too long on this one, driving without proper AC function could lead to bigger problems in hybrid models.

Thanks so much for sharing your experience! The situation sounds exactly like what I'm dealing with right now. Really helpful to know about those expansion valves, makes total sense why my AC completely gave up. Guess I'll bite the bullet and take it to the certified center. Hey, would you mind sharing how much the repair ended up costing you? Also curious if you've had any other AC problems since getting it fixed? Appreciate your detailed response, definitely saved me from taking it to my regular mechanic who'd probably be in over his head with the hybrid system.

Hey again! Glad I could help with the AC issue. After I took my i3 to the certified center, they completely sorted out the problem. The total bill came to 1000 € for fixing those faulty valves in the AC system, definitely not cheap, but worth every penny for getting it done right. The good news is that since the repair, my AC has been working perfectly, no issues whatsoever. It's blowing nice cold air just like when the car was new. Really makes you appreciate having working AC when you need it! I know the cost might seem steep, but considering the complexity of these hybrid systems, it's better to get it done properly the first time. Plus, it's been over a year now with zero problems, so I'd say it was money well spent. Just make sure they give you a proper warranty on the work, mine came with a 12-month guarantee which was reassuring. Keep us posted on how your repair goes!

Just got back from the certified BMW center, what an experience! You were spot on about everything. Took my i8 in yesterday and they found those faulty valves you mentioned, plus some other worn-out components in the AC system. The bill was actually a bit higher than yours, around 1200 €, but honestly, I'm just relieved it's fixed. The service was really professional. They walked me through everything they were doing and explained why the regular mechanic probably wouldn't have been able to handle it. The car feels amazing now, AC's working perfectly and they even caught a small issue with the cooling system that could've caused problems later. Thanks again for pushing me to go to the certified center. Would've been a nightmare if I'd tried to save money by going somewhere else. Definitely keeping your advice in mind for future repairs. These hybrid systems really do need specialized care!
