BMW M4 Multiple Error Codes: Help Needed

Hey there! I have some experience working on BMWs. Last year, I had a similar issue with my 2019 BMW M3, and I totally get your frustration with those error messages. The symptoms were exactly like what you're describing, multiple errors popping up everywhere. Initially, I thought it was something major, but it turned out to be a software coding issue. Took it to my workshop, and they had to reprogram the vehicle control modules. The whole thing cost me about 360 Euro, but it fixed the problem completely. Can you share more details about when these errors started appearing? Also, does your M4 show any performance issues or strange behavior besides the error messages? This would help me understand if you're facing the same problem I had. If it's just error messages without any driving issues, it's likely a coding problem, especially since these newer BMWs are pretty complex with their electronics. Still, it's best to have it checked out to be sure.

Thanks for sharing your experience! Yeah, I'm leaning towards it being a software issue too, my car's been running perfectly fine performance-wise, just these annoying messages keep popping up. Mine's at 176906 KM and had its last service about 2 months ago, everything was fine until last week when this started happening. Haven't noticed any actual driving problems, which makes me feel a bit better about it not being mechanical. Guess I'll have to bite the bullet and take it to the workshop for a diagnostic check. Really hoping it's just a simple coding fix like yours was! Did your errors also come up out of nowhere, or was there any specific pattern you noticed?

Hey again! Yeah, those error messages on my M3 were super unusual at first, they'd just pop up out of nowhere while driving. Sometimes they'd show up right after starting the car, other times in the middle of a drive. There wasn't really a pattern I could figure out, which was pretty frustrating. Since you mentioned yours started after being fine for two months post-service, it reminds me exactly of my situation. My problems actually started about 6-7 weeks after a routine service too. Weird coincidence, right? I remember being extra annoyed because everything was perfect during the service. One thing I forgot to mention in my first reply, before taking it to the workshop, I tried the old "turn it off and on again" trick several times (disconnecting the battery for about 30 minutes). It temporarily cleared the messages, but they kept coming back after a day or two. That's when I knew it had to be something deeper in the software. The good news is that since you're not experiencing any actual performance issues, just like I wasn't, it's probably nothing serious. The newer BMWs can be super sensitive with their electronics, but usually, these ghostly error messages are just coding problems. Keep us posted on what your workshop finds!

Thanks so much for the detailed follow-up! It's actually really reassuring to hear your experience was so similar to mine. I actually tried that battery disconnect trick too yesterday, had the exact same result where the messages disappeared briefly but came right back. Guess great minds think alike! I've gone ahead and booked my car in for next week. Really hoping it'll be a straightforward fix like yours was. The timing thing with the service is super interesting, makes me wonder if something got triggered during the routine updates they usually do. I'll definitely update this thread once I get it sorted. Really appreciate you taking the time to share your experience, it's helped calm my nerves about the whole situation. At least I can drive knowing it's probably just the computer being dramatic rather than anything seriously wrong with the car!
