BMW i4 Climate Control Panel Issues, Help Needed

Hey there! (Some experience with EVs) I had a super similar issue with my 2020 BMW iX3 last winter. The climate control system was acting up exactly like yours, flashing panel, no AC, weak heat. Turned out to be a faulty wiring connection to the control module. Took it to my regular workshop, and they diagnosed it pretty quickly. Had to replace some corroded cables and reconnect the plug properly. The whole thing, including diagnostic and labor, cost me 95 Euro. Now it's working perfectly fine! Before I can give more specific advice, could you share: Have you noticed any error messages on the main display? Does this happen all the time or just occasionally? Did it start suddenly or gradually get worse? BTW, I'm a big fan of the i4! Honestly, it handles even better than my iX3.

Hey! Thanks for the info! Just had my latest service done last week actually. My i4 is sitting at 101742 KM, but this issue started popping up about two days ago. The climate control just stopped working completely out of nowhere, no gradual decline or warning signs. And yeah, I'm getting an "Error: Climate Control System" message on the main display constantly. It's not intermittent at all, it's consistently malfunctioning since it started. Really appreciate the heads up about the wiring connection issue, that sounds like it could be similar to what I'm experiencing. Definitely gives me a good starting point to discuss with the techs. Crossing fingers it's just a wiring issue like yours and nothing more serious!

Hey again! Thanks for those extra details about your i4. Yeah, that sudden failure and error message sounds exactly like what I experienced with my iX3. The consistent nature of the problem rather than it being intermittent actually makes me even more convinced it's similar to what I dealt with. Since you mentioned having service done last week, I'm wondering if maybe something got knocked loose during the maintenance. With my iX3, the techs found that moisture had gotten into one of the connectors and caused corrosion, but they also mentioned these issues can sometimes pop up after routine maintenance if a connection wasn't seated properly. The fact that you're getting that specific error message on the display is actually good news, it's the same one I had. My repair was pretty straightforward once they identified the exact connector that was causing trouble. Just make sure they check all the wiring connections to the climate control module thoroughly. In my case, they actually found a bit of damage to the insulation on one of the wires too, which they fixed while they were in there. Keep us posted on what you find out! Always curious to hear if these issues end up being similar across our BMWs.

Thanks for the detailed follow-up! That's really reassuring to hear that it might be connected to the recent service. I hadn't even considered that possibility, but it makes total sense. I just called the service center and managed to get an appointment for tomorrow morning. I'll definitely ask them to check those wiring connections first, especially around the climate control module. The fact that your repair was straightforward and relatively inexpensive is such a relief, I was imagining all sorts of costly scenarios! I really appreciate you taking the time to share your experience. It's helped calm my nerves about the whole situation, and now I feel much better prepared for the service appointment. I'll update this thread once I find out what the actual issue was. Fingers crossed it's just a loose connection from last week's service! Thanks again for all your help!
