Thanks for the detailed response! My car's got 83099 KM on it, and I actually had the last service done recently. When I try to turn on the A/C, there's absolutely no noise, just dead silence. The error codes I'm getting are P0645 and P0562, which seem to point to an electrical issue like you mentioned. Haven't noticed any other electrical problems though. Based on what you're saying about your experience, it sounds pretty similar to my situation. Honestly, it's a relief to hear yours was fixable without any major drama. Did your workshop mention how long the repair typically takes? I'm trying to figure out if I should expect to be without the car for a while.
Hey again! those error codes you mentioned, P0645 and P0562, are exactly what I saw with my 3 Series too! And yeah, the complete silence when trying to turn on the A/C is super familiar. That's exactly how mine was behaving. The repair on my car actually didn't take too long at all. My workshop had it done in about 4-5 hours. They found that the A/C compressor clutch relay was faulty, and there was also a voltage drop issue that needed fixing. The techs also checked the fuse box while they were at it, just to be thorough. Since your mileage is pretty close to what mine was when this happened (I was at around 79000 KM), I'm even more convinced it's the same issue. The good news is that it's totally fixable and not one of those nightmare repairs that takes forever or costs a fortune. Just make sure your workshop does a proper electrical system check before just swapping parts. My mechanic said that's crucial with these kinds of symptoms. And based on my experience, I'd recommend getting it sorted soon, I tried driving without A/C for a week and absolutely regretted it! Let me know how it goes when you get it checked out. I'm curious if it turns out to be the same problem!
Thanks so much for sharing your experience! It's super helpful to hear from someone who went through the same thing. I've gone ahead and booked my car in at the workshop for tomorrow morning. They seemed pretty confident after I mentioned those error codes and symptoms, especially since they match up so well with what you dealt with. The service advisor actually mentioned the same thing about the compressor clutch relay being a common failure point in these models. They estimated about 4-5 hours for the repair, just like in your case, which works perfectly with my schedule. Really appreciate you mentioning about getting the full electrical system check too, I made sure to specifically request that when I made the booking. Much rather have them do a thorough job than miss something and have to deal with this again. I'll definitely post an update once it's fixed. This electrical stuff can be tricky, but you've made me feel much better about the whole situation. Who knows, maybe this info will help out another BMW owner down the line! Thanks again for taking the time to share all those details about your repair experience. It's been incredibly helpful in knowing what to expect.
Hey there! I had something very similar happen with my 2017 BMW 3 Series last summer. I've got some experience working on cars, but mainly just basic maintenance stuff. The symptoms you're describing sound exactly like what I dealt with. My A/C completely died, and the initial scan pointed to an undervoltage issue that was causing the compressor to shut off. Took it to my regular workshop, and they confirmed it was an electrical problem affecting the A/C system. The whole repair, including diagnostics and parts, set me back about 240 Euro. Before I can give you more specific advice, could you share: What error codes you're getting exactly? Does your A/C make any noise at all when you try to turn it on? Have you noticed any other electrical issues recently? Let me know these details, and I might be able to help you figure out if you're dealing with the same problem I had.
