If you have a smart phone or tablet, get an OBDII app and wireless adapter to see exactly what is going on with the engine fuel management system.
A quality OBDII tool supports the following:
OBD Fusion | OBDSoftware.net

You'll need a wireless OBD adapter. The bluetooth LE one is by far the best.
Read the attached PDF document on how to configure OBD Fusion and use it to run a Diagnostic Report, log parameters, and share the logs.
This write-up is Android specific. iOS support is similar, but the menu options may be slightly different.

- VeePeak BT LE A Bluetooth LE OBDII adapter works well on both Android and iOS, is more reliable than WiFi, supports higher speeds, but is more expensive. BT LE is not supported on older devices, so first check if your device supports BT LE.
- Veepeak WiFi A WiFi OBDII adapter works with both Android and iOS and is cheaper than BT LE. Some folks have had problems with it losing connection or connecting to other WiFi networks.
- Veepeak Bluetooth For devices other than Apple iOS, a standard Bluetooth OBDII adapter will work and is cheaper than WiFi or BT LE. It does not work on iOS as Apple doesn't support the serial port protocol that BT OBDII adapters use.

Notes
- OBD Fusion supports the OBD standard and does not support any BMW-specific modules or fault codes.
- we recommend OBD Fusion here as it has all the important features, is very reliable, reasonably priced, has excellent support from the developer, and properly supports many OBD PIDs that other apps don't. We have no affiliation with OBD Fusion or its developer OCTech, LLC.
- we recommend the VeePeak brand of OBDII adapters here as they've shown good quality, reliability, stand behind their products, reasonably priced, and readily available. We have no affiliation with VeePeak.
