About this app

bimmer-tool allows to read & clear fault codes, request DPF regeneration, read engine live data and much more in BMW cars.

Try bimmer-tool lite to see whether the app is compatible with your BMW and your OBD adapter.

K+DCan cable is recommened for cars below model year 2008. Connection using a wireless ELM adapter in a car below 2008 may not be possible or not all fuctions will be available.

Important: This application requires a reliable OBD adapter. Cheap adapters will not work. K+D-Can cable, ENET adapter (for F/G series) or below Bluetooth adapters are recommended:

- UniCarScan UCSI-2000/USCI-2100: Choose setting: D-Can mode: MODE2
- Carista
- Veepeak OBDCheck BLE

Application allows to:
- read DPF regeneration status and detailed information
- request DPF regeneration
- reset DPF adaptation values (required after filter replacement)
- read exhaust fumes pressure
- read injectors adjustments
- read actual and expected values for air mass, intake manifold pressure, fuel pressure
- log data to CSV file for further analysis
- register battery replacement (without changing battery properties)
- reset lamps circuits blocked due to short-circuit error
- reset oil/brakes service and change interval**

Supported OBD adapters
- K+D-Can USB: This is recommended and most reliable adapter. You will also need USB-OTG cable.
- ENET cable/Wifi Adapter: recommended for F & G series. ENET cable connections you need additionally USB-C to Ethernet adapter.
- ELM327 Bluetooth: Bluetooth connection may be slower than USB. Only genuine ELM327 or PIC18-based adapters will work. It may not work with older engines. More info below.
- ELM327 WiFi: Like ELM Bluetooth connection may be less stable. On some devices mobile data transmission needs to be disabled to use WiFi adapter.

If you have questions or need any help send me an email. You can find our address at the bottom of the page.

Quick start
1) Connect adapter to OBD II socket
2) Turn ignition on
3) Connect adapter to your phone:
* USB: Connect adapter to the phone using USB-OTG cable. Phone will ask which app to start - choose bimmer-tool app.
* Bluetooth: Go to phone Bluetooth setting. Search for Bluetooth devices and pair the adapter with the phone (PIN is usually 0000 or 1234).
* Wifi: Turn mobile data transmission off. Turn WiFi on and search for available WiFi networks. Connect the phone to the adapter's WiFi.
4) Start the app, go to 'Car' and choose model and year.
5) Go to 'Connection' and choose connection type, adapter type and communication protocol.
6) Tap 'Connect' button.

For mlodels below 2008 and e46/e39/e83/e53 the app requires K+DCan cable connection and only engine ECU is supported. Connection using a wireless ELM adapter may not be possible.

Common problems
- Engine 'No response' error in cars up to 2007 and BT/Wifi adapter. If this error occurs from time to time, try selecting ATWM option under advanced connection settings.
- No connection: If adapter & protocol settings are correct and app still cannot connect to the car try force stop all diagnostic applications in application manager (including bimmer-tool) or restart the phone and try to connect again.

Why this app requires permissions?
- Storage: required for USB adapters support
- Photos / Media / Files: allows to create CSV files
- Pair with Bluetooth devices/access Bluetooth settings: required for Bluetooth adapters support
- Full network access: required for WiFi adapters support
- Approximate location: Theoretically it is possible to find approximate location using Bluetooth, however this app does not read/use location.

Great app and a great value compared to other options out there. I purchased specifically to register a new battery in my vehicle and it worked successfully. I initially had a problem getting it to work, but I contacted the developer and received a very prompt reply helping me go through the process. After following the instructions (ignition off vs ignition on) everything was very smooth.

It's a struggle to get it connected. The lite version connected fine, but after buying the full version it was a half hour long ordeal to get it connected to the ECU. Allows you to reset a few automatic adaptations and trigger the ECU to re-learn them, but not able to change parameters or do any actual tuning. DPF regen might be worth it, but I have a gasoline engine. Live data works ok, but most of it stays in metric even after changing units to U.S.

I liked the lite version so much I decided to buy the BMW tools full version for $16 this person took the time to make the scanner software and let us try it for free. I wanted to say thank you with cash👍😁 Update: I wanted to share my experience : I had an issue with reading boost pressure in the app on my n63 engine. I reached out to the developer and he fixed it in 24 hours !! Thank you sir for your app and your willingness to fix that glitch so Fast
