It provides full system diagnostics, service reset functions and bi-directional control, making it ideal for both home users and workshops working on German vehicles.
Designed for DIY users and professionals who want more than a basic code reader, with fast AutoVIN, live data, Wi-Fi updates and strong vehicle coverage in one easy-to-use handheld scanner.
Who is DE V4.0 best for?
German vehicle owners

Ideal if you want one dedicated tool for multiple German brands without stepping up to a much larger workshop tablet.
DIY and home mechanics
- AutoVIN for quicker vehicle recognition
- Live data in text and graph form
- Bi-directional tests on supported systems
A strong choice if you want more than a basic OBD2 reader and like doing your own servicing and fault finding.
Garages and workshops

Before you buy - quick compatibility check
Coverage can vary by model year, ECU and system. If you want us to confirm exact functions for your vehicle, send your registration number or VIN and tell us what functions you need.
Important: some older vehicles require additional adapters.
- Older Mercedes models with round 38-pin diagnostic ports require a Mercedes 38-pin to OBD2 adapter - this is not included with the scanner
- Standard OBD2 vehicles with a 16-pin port plug straight in
This helps avoid ordering the correct tool but expecting a function or connection that may not be supported on your exact vehicle.
