BMW X3 Engine Struggles: Rough Starts and Strange Noises
Summary of the thread
A 2019 BMW X3 20i is experiencing engine issues, including rough starts, strange noises, and a tendency to shut off shortly after starting, particularly after sitting idle for a few days. The problems include a prolonged cold start, engine shaking, and a petrol smell from the oil cap. Suggested solutions include checking the battery voltage and connections, as a weak or poorly connected battery might cause these symptoms. Replacing an old or weak battery is also recommended.

Check the battery voltage and connections first, as a weak battery can cause starting issues and rough idling. Ensure the battery terminals are clean and tightly connected. If the battery is old or weak, consider replacing it. Let me know how it goes or if you have any further questions!
The battery has been already checked and it's in a very good condition. It was replaced last year with a new one.

Inspect the fuel injectors for any clogs or leaks, as these can cause rough starts and unsteady engine performance. You might also want to check the fuel pressure to ensure it's within the recommended range. Let me know if this helps or if you have any other questions!
