Defender's Electronic Damper Issues & Warning Light Alert

Hey there! I had a similar issue with my 2018 Land Rover Discovery last year, I know these air suspension headaches all too well! I've got some experience working with Land Rovers (owned a Range Rover Sport before). When I got the warning light, I took it to my trusted workshop. Turned out there was a loose cable connection to one of the suspension sensors. The bouncy ride was because the system wasn't getting proper readings. The mechanic traced the issue, fixed the faulty connection, and recalibrated the system, cost me around 155 Euro but totally worth it as it's been smooth sailing since then. Before I share more specific advice, which engine variant do you have? What exactly does the warning message say? Does the bouncing happen more on one side? This could help narrow down if you're dealing with the same issue I had. These electronic systems can be tricky, but usually it's something fixable!

Thanks for your detailed response! I've got the 2.0L gasoline engine with 195161 KM on the clock. The warning just shows "Suspension System Fault" in yellow, nothing more specific. The bouncing seems pretty even on both sides, but it's definitely more noticeable at higher speeds. Had my last service about two months ago, but this issue started just last week. Been reading through the manual but it's not very helpful with these electronic gremlins. Really hoping it's just a sensor issue like yours and not something major with the air compressor or struts. Let me know if you need any other details, really appreciate the help!

Hey again! Thanks for those extra details about your Defender. You know what, that's really similar to how my Discovery was acting up, I've got the same 2.0L engine too! When you mentioned it's bouncing evenly on both sides, that actually makes me more confident it could be similar to what I experienced. In my case, the bouncing got really annoying above 70 km/h, especially on slightly uneven roads. The same yellow warning light too! Here's what I learned from my experience, when the suspension fault shows up with even bouncing on both sides, it's often more of an electronic control issue rather than a mechanical one. After my sensor connection was fixed, they also updated the suspension control module software. Apparently, these systems can get a bit confused over time. Quick tip, before you take it in, try doing a system reset: Turn off the engine, wait about 5 minutes, then restart. Sometimes this can temporarily clear things up, though it didn't fix my issue permanently. Since you mentioned your last service was two months ago, check if the shop can have a look under warranty. My trusted mechanic mentioned these issues often show up around your mileage range. Let me know how it goes, I'm really curious if it's the same gremlin I dealt with!

Thanks so much for all this info, it's super helpful! I actually tried that reset trick you mentioned right after reading your message, and while the warning light went away temporarily, it came back after about 20 minutes of driving. At least now I'm pretty confident it's likely an electronic issue rather than something major with the mechanical components. I've just booked it in with a specialist for next week. You're right about checking the warranty, I called them and since it's suspension-related, they said it might be covered under the extended warranty I got with the car. That's a huge relief! Really appreciate you taking the time to share your experience. It's way less stressful dealing with these issues when you have some idea what you're up against. I'll probably just take it easy on the rough roads until the appointment. Will definitely update the forum once I know what the actual problem was!
