BMW 740 owners have reported 1 problem related to engine funny noise (under the engine and engine cooling category). The most recently reported issues are listed below.
The gas tank started to make popping noises and thumping sounds. Then when I realized something is wrong when the gas gauge started reading 1/4 tank when it was empty, strangely when I was filling up with gas the cap was hard to remove and as soon as I removed the cap air was rushing in. I ran out of gas on the interstate without any warning managed to get the car on the shoulder. Later on the way to work I started smelling a strong gas odor I assumed it was the cars surrounding me. When I went on my lunch break my coworkers informed me that there was a large puddle of gas under my car, when I got back to work I started to investigate what happened and my tank was imploded and developed leaks around the seams. I find this a major concern since this is right next to a hot exhaust system and may cause a fire due to poor gas tank ventilation. I'm lucky that my car didn't catch on fire due to the amount of gas I lost and noticed leaking on the seams that are extremely close to the exhaust.
