P0171, P0507, P1030 codes for BMW 328i xdrive

[Fonza]

I got all three codes and a really rough idle going above 1k rpm at some points. Has anyone had this issue with all 3 fault codes?

Welcome to the forum.

Firstly, you need to identify the car properly. The YEAR is absolutely indispensable information, and the engine is also necessary. Mileage and transmission are also good. Be aware that the "328i xdrive" might be a 4 cylinder turbo, or a six cylinder normally aspirated engine.

P-codes are government emissions codes. They are notoriously inaccurate for diagnosing BMWs. You need to read the BMW manufacturer codes with a good BMW specific scan tool, and write down the code description, in WORDS, for each code. There will likely be additional codes, and there will certainly be much more specific codes.

Now, that said, you have a large intake system leak, unless it's a turbocharged engine, in which case there are several other distinct possibilities.

Read the BMW specific codes.
