📋 Technical Details at a Glance
- Compatibility: Android 7.0 or above, iOS 11.0 or above
- Unsupported architecture: 32-bit smartphones (not supported)
- Connectivity: Bluetooth 5.0
- Wireless range: Up to 10 m (approx 33 ft)

Understand Faults Fast – Full-system DTCs with severity and repair guidance
AutoVIN identifies the vehicle quickly and the app reads and clears fault codes while tagging each DTC as severe or minor. Live numerical and 4-in-1 graph displays turn raw sensor values into clear, actionable information.
Immediate clarity on what matters keeps roadside decisions straightforward and prioritises repairs efficiently. Bear in mind that dealership-level reprogramming and advanced manufacturer coding are not listed features, so complex module programming will still need a workshop tool.
Keep Maintenance on Track – Six reset services for routine upkeep
Includes Oil Reset, TPMS Reset, BMS Reset, EPB Reset, Throttle Adaptation and DPF Regeneration, each executed via the phone app. The DPF and BMS routines work with live parameters so the system confirms when procedures complete.
Scheduled resets and regenerations cut down unnecessary garage visits and keep the car running cleaner between services. A practical trade-off is the limited set of service functions; owners who require deeper factory-level maintenance actions may still need professional-level tools.
Diagnose On the Move – Bluetooth 5.0 connection with live data and performance tests
Bluetooth 5.0 maintains a wireless link up to around 10 metres, letting the user view real-time gauges and numerical readouts while standing a short distance from the vehicle. Performance Test measures 0–60 mph acceleration and the Battery Test monitors live voltage for battery health checks.
Wireless operation and compact pocket-sized design, roughly the size of a large smartphone, free users to diagnose from a comfortable position beside the car. Note that the app requires a compatible 64-bit Android (7.0+) or iOS (11.0+) phone, and older 32-bit handsets will not connect.

❓ Frequently Asked Questions
Q: Will my phone work with CarPal?
A: The app requires a 64-bit Android 7.0+ or iOS 11.0+ handset; 32-bit phones are not supported. Pro tip: check your phone’s architecture in Settings or on the manufacturer’s spec page before buying, and update the OS to the latest version for best app stability.
Q: Can I save and share diagnostic reports?
A: Live data sessions and recorded reports are available for playback and further analysis within the app. Pro tip: export or back up reports after a session to keep timestamped records for warranty claims or when consulting a garage.
Q: Does CarPal run emissions pre-tests for MOT readiness?
A: Smog Check performs a pre-test of vehicle emissions and records results for review. Pro tip: run the test after the engine reaches normal operating temperature to mirror MOT conditions and improve the chance of an accurate pre-check.
🏆 Our Verdict
The CarPal A is suitable for DIY motorists and mobile mechanics who need quick, wireless diagnostics and routine resets. The combination of AutoVIN, live data visualisation and six maintenance services makes roadside checks and basic servicing faster and clearer. While not a substitute for dealer-level programming, the compact, smartphone-driven workflow delivers strong ongoing value for everyday vehicle care.
