Drivetrain Malfunction and Hissing Sound - BMW 3 Won't Start
Hello everyone, I'm experiencing a 'Drivetrain Malfunction' warning on my BMW 3, and the car refuses to start. All systems seem to have power, so I don't suspect the battery is the issue. Additionally, there's a hissing sound coming from the mid-undercarriage that lasts for a few minutes after turning the car off. I don't recall hearing this sound before. Has anyone encountered a similar issue or have any insights on what might be causing these problems? Any advice would be greatly appreciated!

Start by checking for any visible leaks or damage to the exhaust system, as the hissing sound could indicate an exhaust leak. This might also relate to the drivetrain warning. If nothing is visible, have a mechanic inspect it, as exhaust leaks can be hazardous. Let me know how it goes or if you have more questions!
