I've used this little OBDII sensor so many times, that it already paid for itself. It was not very expensive to begin with, only $20 dollars US. It has been a life saver many times over. I have diagnosed many problems in my E90. The product is a Bluetooth OBDII adaptor. The one I got was from Amazon, it's from a company called XiTech, the model is XR7.
You only have to pair it with your phone one time, and after that you only have to connect the adaptor to your car and then run the app.
To Pair: Plug in the XR7 into your cars OBDII, then Turn on Bluetooth on your Phone and search for the device on your phone, mine comes up as CBT, select it to pair with phone, you may need to enter a 4 digit code, mine was included in the paperwork I got with the device, usually it's 0000 or 1234, then run the Torque App. Wait for the device to link with the bluetooth and you are ready to read the codes or run the Real Time Information.

When I get the dreaded Check Engine Light in my car, the first thing I do is I plug in the XR7 and I run the app, with in seconds I know what is wrong with my E90.
If you go to the Dealer to get an Engine check light diagnosed, it will run you $150 dollars US. Why spend that much money when you can diagnose the problem yourself.
A must have for any BMW E90 owner.
