Help with engine problems with my BMW 1

Start by checking the oil level and quality to ensure it's not low or degraded, as this could affect oil pressure and engine performance. If the oil level is fine, inspect the oil pressure sensor for faults or damage. Since the issue involves misfires and rough running, consider checking the fuel injectors for clogs or malfunctions. If the problem continues, it might be wise to have a professional mechanic inspect the vehicle, especially since it involves multiple systems. Let me know how it goes or if you have further questions!
