BMW 6 Air Suspension Failure Causing Uneven Ride Height

I faced almost identical issues with my 2015 BMW 5 Series 530d last month. The control rod sensor was defective, causing irregular height readings and misaligned headlights. The warning light came on during highway driving. Had it checked at my regular garage, turns out the control rod sensor was corroded and sending false signals to the suspension control unit. The mechanic had to replace both the sensor and clean the connecting terminals. It wasn't a major repair but definitely needed immediate attention to prevent damage to the air suspension system. The symptoms you describe match my experience exactly. If left unchecked, it could lead to uneven tire wear and potentially damage other suspension components. Make sure whoever fixes it uses proper BMW diagnostic tools and original parts. My car's been running perfectly since the repair, back to its normal ride height and properly aligned headlights.

Thanks for sharing your experience! This is super helpful as I'm dealing with the exact same symptoms. Good to hear you got it sorted. Quick question, do you remember roughly how much the repair set you back? Also, has everything been running smoothly since the fix, or have you noticed any other quirks pop up? Just want to make sure I'm prepared for what I might be facing.

Hey again! Just wanted to follow up, super happy to report that everything's been running perfectly since I had it fixed. The total repair came to 110 € for replacing the control rod sensor and cleaning those connections. Money well spent if you ask me! The "Height control restricted" warning completely disappeared as soon as they sorted it, and my suspension's been working like a charm. No more uneven ride height or wonky headlights, honestly feels like my BMW's back to its old self. Trust me, it was worth getting it done properly. Haven't had a single issue since the repair, and it's been about a month now. The car rides beautifully, just like it should. I was worried it might come back or cause other problems, but nope, smooth sailing all the way! If you're dealing with the same thing, I'd definitely recommend getting it checked out soon. Better to fix it now than wait for bigger issues to develop.

Thanks everyone for the great advice! Wanted to update you all on how things turned out. Finally got my BMW sorted at a certified mechanic after that sketchy experience I mentioned. You were spot on, it was indeed the control rod sensor causing all the trouble. The mechanic found corrosion on the sensor and some damaged wiring, just like what others experienced. They replaced the faulty parts and cleaned up all the connections. The whole job was surprisingly reasonable, around what others mentioned paying. My car's now sitting perfectly level again, and those misaligned headlights are fixed too. Best part? The warning light's completely gone and the suspension's working exactly like it should. Such a relief to have this sorted properly! Really glad I didn't wait any longer, learned my lesson about dealing with trusted mechanics who know BMWs. Thanks again for helping me avoid what could've been a much bigger headache! Now I can finally enjoy driving my 6er without worrying about every little bump in the road. Money well spent, if you ask me!
