I bought a elm 327, that scould work whith my andoid phone whith bluetooth. But it dosent... does my beast support obd 2. its from 2000 with a obd plug under the dash, and a round service plug under the hood. The program i use one my phone is torque from android. It conect whith the phone and searces for the ecu, but says end the end " cannot conect to ecu" Here is some info on the elm scanner:

Bluetooth ELM327 OBD2 fault code reader.
Wireless connectivity via Bluetooth.
Supports CAN bus!
Perfect for Android, for example, together with free program Torque:

Works on particular Android 2.0 and later, Windows Mobile, Windows (PC), Linux, etc.

Now it is no more hassle with cables when it comes to diagnosed the car.
Just plug the device, plug ignition of the car and connect wirelessly from your laptop or handheld device.

Through the wire read interface it is possible to read and reset the generic and manufacturer specific trouble codes and monitor a wide range of engine values and read the VIN data.

Works for most cars produced from 1996 to today (see more below).

Why use an OBDII reader?
Although one does not repair cars, you can save money by themselves to diagnose your car. It is now possible even to read out any error codes and decide whether it is a transient error you want to reset itself, so "check engine " light does not light up anymore.

You can also use the reader to check a car before purchase. Not all errors on the motor results in the "check engine " light Fault Code Reader allows you to see these errors!

This product can of course also be used by professional mechanics who are tired of that hassle of wires.

Supported OBDII Protocols
ISO 9141-2
ISO 14230 (KWP2000)

What is CAN / CANbus?
Controller Area Network (CAN) is the newest protocol within automotive.CAN protocol is approximately 50 times faster than previous protocols.
They began to use CAN in some cars of 2003 and 2007, all cars reportedly using CAN.

Sensor data:
The following sensor data can be displayed for most cars (note that there is a difference in how much data the car makes available):
Engine speed
Relative load
Coolant Temperature
Fuel system status
The car's speed
Short Term Fuel Trim
Long Term Fuel Trim
Intake manifold pressure
Timing Advance
Intake air temperature
Accelerator position
Oxygen sensor voltages / associated short term fuel trim
Fuel pressure
Many more ..

Includes some programs to output the values, etc.
Many more can be downloaded from the network for both Windows, Iphone, Android and Windows Mobile.
Note that it is hardware purchased and the included software is only a courtesy. For this reason we can not provide support for the programs.

It maybe your units,but there is a problem with M5s communicating with OBDII. There is factory updated software that fixes this issue. BMW has all the vins on file so you might take your vin to a BMW dealer and ask them if you have had the update, if not get it.

Set up the profile in Torque for the M5 properly. I set up the profile fine for the Mini and then it wouldn't connect to the M5 until I switched to the correct profile.

I went into elms BMW in cambridge today and asked about this.nthey said there may be an update available but they charge an hours labour at 125 quid. I want to be sure it will fix the issue first...

Are there people using iPhone apps with the wifi dongles on the board?

The U.S. update was free so the inspection equipment could talk to the M5. It sounds like it also caused the oversensitive throttle some have.

Good Luck,

Sailor - whats this about configuring something. sorry I'm a noob here. do you mean some settings need changing on the ECU to enable it to talk OBD properly? What settings are these? I need to know so I know what to ask for when taking the car to the Autologic guy...

EDIT: This thread is regarding the update also I take it?

Don't mean to confuse but I just faced this last night.Car was updated because it would not communicate with an OBDII tool. Once updated the settings in the car changed so I had to clear the settings in the tool and start again then no problem, but something got stored in the device so after the update it was confused. Don't know your produce but the same may apply.

Oh I see, its the scan tool that remembered some information. That makes sense. Thanks.

I would also like to know actually if the fuelling and ignition maps etc get wiped when the DME is updated. Does anyone know? I have a feeling I might have an existing tune on the ECU. The M5 I have has a lot of factory AC Schnitzer bits on. the previous owner seemed to think it had a tune.
