Help with engine problems with my BMW 1

Hello everyone, I own a BMW 1 (2010, gasoline) with 137,000 km mileage and have some problems: The oil light is on, the engine is running rough, the check engine light is on, it jerks when accelerating, and the engine dies at idle. I have a BMW e87 118i with 140,000 km and it started with my car running extremely rough in the mornings and stalling at idle, after which the check engine light came on. After reading out the codes, errors such as misfire cylinder 4, lambda control, and oil pressure control were displayed. I have changed all 4 spark plugs and ignition coils, but the problem persists. Does anyone have an idea how I should proceed? I am grateful for any help!

Summary of the thread

The BMW 1 is experiencing several engine issues, including the oil light being on, rough running, check engine light activation, jerking during acceleration, and stalling at idle. The problems persisted despite changing spark plugs and ignition coils, with diagnostic codes indicating misfire in cylinder 4, lambda control, and oil pressure control errors. Suggested solutions include checking the oil level and quality, inspecting the oil pressure sensor, and examining the fuel injectors for clogs or malfunctions. If unresolved, consulting a professional mechanic is recommended.

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!
