Defender Hybrid ABS Warning: Speed Sensor Mystery

Hi there! As someone with some car repair experience, I had a similar issue with my 2020 Range Rover Sport Hybrid. Those warning lights can be super annoying, right? In my case, it turned out to be a faulty ABS control unit, not just a sensor. The workshop diagnosed it after a thorough check, and I ended up paying about 1000 Euro for the replacement unit plus labor. A bit pricey, but it fixed the problem completely. You might be dealing with something similar since Land Rover uses comparable systems across their models. What's your mileage, and have you noticed any other symptoms? Like unusual brake pedal feel or traction issues? This info would help determine if you're facing the same problem I had. Quick tip: Don't ignore those warning lights, better to get it checked soon to avoid any safety issues!

Thanks for sharing your experience! My Defender has 196224 KM on the clock and just had its service last month. I haven't noticed any unusual brake pedal feel, but there's a slight vibration when braking at higher speeds. I was hoping it would just be a sensor issue, but hearing about your ABS control unit problem has me a bit worried now. Did you notice any vibrations before your unit failed completely? These repairs can really hit the wallet hard, but you're right, safety comes first. I'll get it checked out at the workshop this week. Really appreciate your detailed response and the heads up about the potential costs. Better to deal with it now than have bigger problems later!

Hey again! Good to hear back from you. Yeah, now that you mention the vibration during braking, that's exactly what I experienced with my Range Rover before the ABS control unit completely failed. The vibration started subtle but got more noticeable over time, especially during highway driving. Since your car has quite a few kilometers on it, it's quite possible you're facing the same issue I had. The ABS control unit typically lasts a long time, but they do eventually wear out. Mine failed at around 180,000 KM, so pretty similar to your situation. One thing I forgot to mention in my previous reply, before taking it to the workshop, I tried clearing the error codes with a basic OBD scanner, but they kept coming back. That's when I knew it wasn't just a temporary glitch. Good call on getting it checked soon! Just make sure they do a proper diagnostic check. When they fixed mine, they also updated the control unit's software, which apparently helps prevent future issues. Let me know how it goes at the workshop, fingers crossed it's something simpler than what I dealt with!

Thanks so much for the additional details! That's really helpful to know about the vibrations getting worse over time, sounds exactly like what I'm experiencing. The similarity in mileage when your unit failed is quite telling too. I actually have a basic OBD scanner in my garage, so I might try clearing the codes before heading to the workshop, just to rule out any temporary glitches like you mentioned. Though from what you're describing, I'm preparing myself mentally (and financially!) for an ABS control unit replacement. Really appreciate you mentioning the software update too, I'll make sure to ask about that when I take it in. I'll definitely update this thread once I get the diagnosis and repair done. Hopefully it helps others who might face similar issues with their Defenders or Range Rovers in the future. Thanks again for taking the time to share your experience, it's really helped me understand what I might be dealing with!
