Astra Fuel Door Won't Unlock, CEL Warning Troubles

Hey! I had a similar issue with my '08 Vauxhall Vectra 1.9 CDTI last year. The warning lights and fuel flap problem you're describing sound exactly like what I experienced. Turned out to be a faulty fuel flap actuator linkage. Took it to my local garage and they diagnosed it pretty quickly. The mechanic showed me that the linkage mechanism had worn out and wasn't responding properly to the release switch. It was more than just a simple fix, they had to replace the entire actuator assembly. Not a major mechanical issue that affects engine performance, but definitely something that needs sorting to avoid getting stranded at a fuel station. Got it all fixed in about half a day's work. If you're near Manchester, I can recommend my mechanic, he specializes in Vauxhalls and didn't try to upsell me on unnecessary work. Hope this helps!

Hey, thanks for sharing that! Really helpful to hear someone else had the same problem. Yeah, sounds spot on with what I'm dealing with. Do you remember roughly how much you ended up paying for the actuator replacement? And has everything been working smoothly since then, or did any other issues pop up? Cheers!

Hey again! Since you asked, yeah, I paid around 210€ for the whole job, including parts and labor. The mechanic sorted it out pretty quickly, and I'm happy to say the fuel flap has been working perfectly since then. Not a single problem in over a year now! It's actually such a relief not having to mess around with the flap anymore or worry about getting stuck at petrol stations. The repair was totally worth it. Honestly, the linkage was definitely the culprit in my case, and once they replaced that, all the warning lights disappeared too. My Vectra's been running great otherwise, no related issues have popped up since. If you end up getting it fixed, you'll probably have the same experience. These things are usually pretty straightforward once you get them sorted by someone who knows what they're doing. Let me know how you get on with it!

Thanks so much for the follow-up! I actually just got back from the mechanic today. Took your advice and found someone who specializes in Vauxhalls. You were right about everything! The fix cost me about 225€, so pretty close to what you paid. Turned out to be exactly the same issue, faulty fuel flap actuator. The mechanic was really good, showed me the worn-out parts and explained everything clearly. Got it done in about 4 hours, and now the flap's working perfectly. All those annoying warning lights are gone too! Really glad I asked here and got your input. Would've probably spent ages worrying about some major engine problem otherwise! Thanks again for sharing your experience, helped me avoid a lot of stress and probably saved me from getting overcharged somewhere else. Cheers for all the help!
