I am having this issue with my 2008 E70 X5 (N52 engine). My main issue has been the Cold Start rough idling issue I've been experiencing for the past couple of months. Recently - I've decided to tackle the problem by throwing various replacement parts at it (Intake Vanos Solenoid, Exhause Vanos Solenoid, MAF Sensor). These parts are BMW parts just to be on the safe side. They did not fix the issue with the cold start. I also plan on the doing a leak check tonight to verify that there are no leaks.
This morning, I received the following CEL lights after drving the car for several miles (P116E, P0171, P0174) so I decided to capture that Diagnostic Report per OBD Fusion App. I have attached it to this post in hope that someone can review and help me troubleshoot the issue. Thank you.
