For BMW & MINI
Inspect the BMW or MINI you drive, or the one you’re about to buy. Your phone reads what the car’s own computers know about its engine, gearbox, battery and mileage.
For iPhone and iPad. Android coming later.

All you need is your phone and an OBD adapter.
A compatible Bluetooth, Wi-Fi or ENET adapter goes into the port under the dashboard.
Start the engine, open BimmerInspect and follow the guided check.
For free, you see how much data your car provided. The results and the PDF are in the full report, a one-time purchase.
Some engine checks need a warm, idling engine. If a condition isn’t met, you get a partial result instead of a guess. Which adapter?

A quality ELM327-compatible Bluetooth or Wi-Fi OBD-II adapter, or an ENET cable with a suitable Ethernet adapter for your phone. Cheap copies may not support every command the inspection needs.
