Faulty unlocking of the fuel filler flap and illuminated warning lights in BMW 5 Series Diesel, model year 2018: experiences and possible solutions

Hi, I had a similar problem with my BMW 7 Series Diesel, built in 2016. Let's just call it "some experience" with cars, I'm not a professional, but I've repaired a few things myself. With my BMW, it turned out that the linkage was defective. I had it repaired at my usual garage. They replaced the broken linkage and it cost about 210 euros. Since then the problem has been fixed and I have had no more warning lights. Can you perhaps describe the exact symptoms or provide any fault codes? That would help to understand your problem better and give more details.

Thank you for your answer. Unfortunately, I don't have any fault codes to hand as my car doesn't provide any detailed information. But I can say that the car does not show any special driving behavior, only the warning lights are on and a message appears in the display that there is an engine fault. By the way, my mileage is 52158 km and the last service was recently. I'll take your tip into consideration and see if it could have something to do with the linkage. Hopefully that is the solution!

Hey, no problem, you're welcome. So, if you haven't noticed any abnormal driving behavior and only the check engine light is on, it could really be a linkage issue or a fuel system issue. You know, sometimes a clogged fuel filter or something can make a difference. But before you spend a lot of money at the garage, I would really recommend reading out the fault memory. There are many independent workshops or mobile diagnostic devices that you can buy on the internet. These can often provide an initial indication of where the problem could be coming from. Errors in the memory can often simply be deleted and then disappear for the time being. Maybe that will help! But remember, if the check engine light comes on again, you should definitely go to the workshop. Good luck with the troubleshooting, hopefully the problem can be solved soon!

Thanks for the helpful tip. I will get myself one of those mobile diagnostic devices and read out the fault memory myself. Maybe it really is a clogged fuel filter or the linkage. And of course, if the check engine light comes on again, then I will definitely go to the garage. I really hope that the problem will be fixed soon. Thanks again for your help!
