Review on 🚗 ANCEL BD300 Bluetooth BMW/Mini OBD1 OBD2 Scanner: Read/Erase Error Codes, Reset Services & Enhance Diagnostic Experience by Richard Basque

This device is very compact and easy to use.1. Install the application on your smartphone, no registration is required as it should be.2. Plug it into the car's ODBII port, turn on the car's power supply.3. Turn on Bluetooth on your phone, launch the application and it will search for and connect to the device.4. After you connect, the app will show you a set of vehicle inspection tools. The app will prompt you to turn on or off a specific diagnostic item. If error codes are found, a short description and a search link will be displayed. You can find more information on the Internet. Although this device can be used for all ODBII compliant vehicles, it has a dedicated menu section for BMW vehicles. One of the features of BMW is battery replacement. Very few people know that you cannot simply replace an empty battery with a new one. The new battery must be "registered" in the vehicle control module, otherwise your new battery may have a very short lifespan. Not all car services can or want to do this. Most BMW dealers only want to sell expensive OEM batteries, some may want to register your third battery for a $50-$80 fee. However, this device has a menu item for battery registration. This feature alone is worth the price of the device.
