Discovery Check Engine Light: Fuel Flap Lock Issues?

Hey there! I've got some experience with cars (let's say low experience, mostly basic maintenance and common issues). I had a similar problem with my 2012 Range Rover Sport (gasoline model). The symptoms were exactly like yours, check engine light, warnings, and that annoying fuel flap issue. It turned out to be a faulty linkage mechanism in the fuel door system. Took it to my regular workshop and they diagnosed it pretty quickly. Had to replace the entire linkage assembly which set me back about 210 Euro, but it fixed the problem completely. No more warning lights or fuel door issues since then. Before jumping to conclusions though, could you share: What specific fault codes are you getting? Does the fuel door make any clicking sound when you try to open it? Have you noticed any other electrical issues? With more details, I might be able to confirm if it's the same problem I had with mine.

Thanks for sharing your experience! My Discovery has 52724 KM on the clock and just had its service last month. The fuel door definitely makes that clicking noise you mentioned, but it's more like a weak buzz followed by nothing happening. I'm getting fault code P0457 (I had to check my notes for this). No other electrical gremlins that I can spot, everything else works fine. A bit worried about the repair costs though, 210 Euro seems steep but I guess that's just how it goes with these cars. Did your mechanic mention if this is a common issue? I'm thinking of getting it checked next week, just wanted to be prepared for what they might find. Thanks again for the help! These kinds of issues can be really frustrating to diagnose.

Hey again! Yeah, that P0457 code and the buzzing sound you're describing sounds exactly like what I dealt with on my Rover. Mine had around 60K on it when the issue popped up, so pretty similar mileage to yours. The clicking/buzzing you're hearing is definitely the actuator trying but failing to do its job, that's exactly how mine started. And yeah, my mechanic mentioned it's actually pretty common on these models, especially once they hit the 50-60K mark. Something about the mechanism getting worn out over time. About the cost, I know, it made me wince too! But honestly, after dealing with Range Rover repairs, 210 Euro ended up being not so bad compared to some other issues I've faced. The good news is, once it's fixed, it's usually sorted for good. Mine's been working perfectly for the past year and a half. Quick tip though, when you take it in, ask them to check the wiring around the mechanism too. In my case, they found a slightly corroded connector that they cleaned up while they were in there. Might save you from future headaches! Let me know how it goes when you get it checked out. Always curious to hear if others have the same experience I did with these fixes.

Thanks so much for all this detailed info! Really helpful to hear from someone who's been through the exact same thing. The fact that yours has been working perfectly for a year and a half is super reassuring. I'll definitely ask about that wiring check you mentioned, smart thinking! I've just booked it in for next Tuesday, and I feel much better prepared now knowing what to expect. You're right about the repair costs, I've been looking through some forums since my last message, and 210 Euro does seem pretty reasonable compared to some other potential issues these cars can have. Honestly, it's such a relief to know this is a common thing and not some weird one-off problem. I was worried it might be something major! I'll keep your advice in mind about the connectors too. Thanks again for taking the time to share your experience, it's made this whole situation way less stressful!
