The Viecar 4.0 Bluetooth OBD2 scanner is a compact, high-quality diagnostic tool that allows you to read and clear fault codes, monitor live sensor data, and analyse your driving — all from your smartphone or PC. Unlike many budget scanners, this model uses Bluetooth 4.0 dual mode, meaning it works with both iOS and Android devices, plus some Windows PCs with Bluetooth.

Simply plug it into your car’s OBD2 port and connect using the free Viecar app (available on the App Store and Google Play) or a third-party app like Torque or Car Scanner. The scanner is compatible with most petrol vehicles from 2001+ and diesel vehicles from 2004+ that use the OBD2 system.

This device is ideal for everyday drivers, mechanics, or car enthusiasts who want to save time and money by diagnosing issues at home and tracking driving performance in detail.
