BMW iX2 Suspension Warning: Damping System Problems?

Hey there! I've got some experience with EVs as a hobby mechanic. Had a similar issue with my 2022 BMW i4 (also own an iX3). Got those exact symptoms, warning lights, error codes, and that awful floaty suspension feel. Took it to my regular workshop and turned out it was just a damaged wiring connection to the electronic damper control unit. Some cables were loose and had connection issues. Total fix was 95 Euro, mostly labor costs for diagnosing and fixing the connection. Pretty straightforward repair once they found the actual problem. Been working perfectly since then. Before I share more details though, can you tell me if you're getting any specific error codes? Also, does the suspension feel equally bad on all corners or is it more noticeable on one side? This would help narrow things down.

Thanks for sharing your experience! My iX2 just hit 178455 KM and had its latest service two months ago. I'm getting error code E-4587 on the dash display. The floaty feeling seems more pronounced on the passenger side, especially when going over bumps. It's good to hear your repair was straightforward and relatively inexpensive. I'll check the wiring connections you mentioned before taking it to the workshop. The suspension was working perfectly fine until last week, so a loose connection makes sense.

Hey again! Ah, that E-4587 code is exactly what I got with my i4! And the passenger side being more affected, yep, sounds really familiar. Since you mentioned checking the wiring, let me share what I learned from my experience. In my case, the wiring issue was specifically near the wheel well on the passenger side, where moisture had gotten in and corroded some connections. With that mileage on your iX2, it's quite possible you're dealing with the same thing. When I first noticed mine, I actually tried cleaning the connections myself with electrical contact cleaner, but that was just a temporary fix. The warning light came back after a few days. The workshop ended up replacing the entire wiring harness for that section since the corrosion had spread. One thing I'd suggest before taking it in, check if the issue gets worse after driving through rain or washing the car. That's usually a dead giveaway for moisture-related electrical problems. Also, while you're checking connections, pay special attention to the area near the strut tower, that's where my loose connection was. Let me know what you find. If it's similar to what I experienced, you might want to skip the DIY attempts and go straight to the workshop. The labor cost should be reasonable since they won't need to spend time diagnosing what's already a known issue.

Thanks so much for the detailed advice! You're absolutely right, now that you mention it, I noticed the suspension feels particularly bad after washing the car or driving in wet conditions. I just checked the passenger side wheel well area and found some pretty corroded connectors, exactly where you described. Won't bother with DIY fixes since your experience shows it's just a temporary solution. Really appreciate you pointing me in the right direction, I've booked it into the workshop for next week. They said they're familiar with this issue and quoted around 120 Euro for parts and labor, which sounds reasonable. I'll make sure they check the entire wiring harness while they're at it. Thanks again for all your help with this!
