In the BMW e46, error codes E3 and E4 indicate an issue with the oxygen sensor adaptation limits for cylinders 1-3 and 4-6 respectively. This suggests the engine is running too lean, which could be caused by faulty O2 sensors, a vacuum leak, or a malfunctioning EGR system. To troubleshoot, start by conducting a smoke test to detect any vacuum leaks in the exhaust system. Following the smoke test, check for remaining vacuum leaks. If no leaks are found, verify fuel pressure and consider replacing the O2 sensors as a precaution.

I think the issue is with the intake boots that may need to be replaced. The E3/E4 error codes indicate that your engine is drawing in unmeasured air, causing the O2 sensors to detect a lean mixture or malfunction. I'm not sure how the fuel pump, mentioned in a previous response, could be connected to these specific error codes.
