Who Is the iCarsoft POR V4.0 For?
The POR V4.0 is well suited to Porsche owners, enthusiasts and independent workshops that need more than basic OBD2 fault-code reading.
It is a strong choice if you want to diagnose faults across multiple Porsche control systems, perform maintenance procedures, run active component tests and use advanced Porsche-specific diagnostic functions without moving to a subscription-based workshop platform.
Full-System Porsche Diagnostics
Unlike a basic Porsche OBD2 scanner that mainly communicates with the engine control unit, the iCarsoft POR V4.0 can access numerous control modules throughout supported Porsche vehicles.
Depending on the vehicle, diagnostic access can include:
- Engine
- Automatic transmission
- ABS
- Airbag / SRS
- Electronic parking brake
- Steering systems
- Body control modules
- Climate control
- Instrument cluster
- Battery management
- Lighting and comfort systems
- Other manufacturer-specific control modules
Functions include reading and clearing diagnostic trouble codes, viewing live data, system scanning, AutoVIN vehicle identification and access to Porsche-specific diagnostic information.
Full Bidirectional Control and Active Tests
The POR V4.0 supports full bidirectional diagnostics, allowing the scanner to send commands directly to supported vehicle control modules. This helps test components during troubleshooting instead of relying only on fault codes and live data.
Depending on the vehicle and control module, active tests can include functions such as:
- ABS pump activation
- Window regulator tests
- Fuel pump activation
- Fuel injector tests
- EGR valve actuation
- Cooling fan activation
- Transmission solenoid tests
- Other supported actuators
The manufacturer lists more than 19 active-test categories, although exact availability depends on the vehicle and installed control modules.
28 Service and Maintenance Functions
The iCarsoft POR V4.0 includes 28 service and maintenance functions for supported Porsche vehicles. These consist of 9 commonly used maintenance functions and 19 higher-level service functions.
Common Service Functions
- Oil / service reset
- Electronic parking brake / brake pad service
- Electronic throttle control
- Steering angle sensor calibration
- DPF regeneration
- Injector coding
- ABS bleeding
- Battery management reset
- TPMS reset
Additional advanced service functions are available depending on the Porsche model, production year and control unit.
POR V3.0 vs POR V4.0
The POR V4.0 is the successor to the POR V3.0. Both provide full-system Porsche diagnostics and bidirectional active tests, but the V4.0 introduces major hardware and usability improvements.
| Feature | POR V3.0 | POR V4.0 |
|---|---|---|
| Porsche diagnostics | Yes | Yes |
| Full-system diagnostics | Yes | Yes |
| Bidirectional / Active Tests | Yes | Yes |
| Display | 4-inch | 5-inch touchscreen |
| Operating system | Traditional interface | Android |
| Software updates | USB | Wi-Fi |
| Additional vehicle groups | No | 2 included free |
| CAN-FD | Supported | Supported |
| Lifetime free updates | Yes | Yes |
For users comparing the two versions, the biggest V4.0 improvements are the 5-inch touchscreen, Android platform, Wi-Fi updating and two additional vehicle make groups.
Porsche Vehicle Coverage
The POR V4.0 comes pre-installed with dedicated diagnostic software for Porsche vehicles. The manufacturer states compatibility with supported Porsche models from approximately 1996 to 2025.
Exact diagnostic, service and active-test coverage depends on the vehicle model, production year and installed control units.
Two Additional Vehicle Make Groups Included
In addition to the pre-installed Porsche software, the POR V4.0 allows you to download two additional supported vehicle make groups free of charge.
This gives the device three vehicle groups in total without additional diagnostic software subscription fees.
CAN-FD Support
The iCarsoft POR V4.0 supports the newer CAN-FD communication protocol used on newer Porsche platforms.
It also supports traditional automotive communication protocols for older vehicles.
AutoVIN Vehicle Identification
The AutoVIN function can automatically identify supported Porsche vehicles through the diagnostic connection, reducing the need to manually enter vehicle information.
If AutoVIN does not identify a particular vehicle, manual vehicle selection can still be used.
Lifetime Free Wi-Fi Updates
Software updates for the POR V4.0 are included for the lifetime of the device. Updates are downloaded directly through Wi-Fi, with no annual diagnostic software subscription fees.
5-Inch Android Touchscreen
The POR V4.0 uses a modern Android-based interface with a 5-inch capacitive touchscreen.
- Android operating system
- 5-inch touchscreen
- Quad-core 1.3 GHz processor
- 32 GB internal storage
- 5000 mAh rechargeable battery
- Approximately 6 hours continuous operating time
- Wi-Fi connectivity
- USB Type-C charging
Diagnostic History and Reports
The POR V4.0 stores diagnostic history so previously tested vehicles and scan results can be accessed again later. Reports can also be saved and shared.
Standard OBD2 / EOBD Functions
In addition to Porsche-specific diagnostics, the POR V4.0 supports standard OBD2 and EOBD functions on compatible vehicles.
- Read fault codes
- Clear fault codes
