Frequently Asked Questions

Everything you need to know.

• Is the software updated regularly? Are updates free?: Yes. POR V4.0 includes lifetime free Wi-Fi software upgrades. No annual subscription required.
• What's the difference between POR V4.0 and the older POR V3.0?: Vehicle make coverage expansion: POR V4.0 allows users to download additionally 2 vehicle make groups. Hardware upgrade: POR V4.0 features upgraded hardware (5-inch touchscreen, Android OS, Quad-Core processor, 32GB storage, 5000mAh battery).
• The POR V4.0 cannot recognize my vehicle by AutoVIN, does it mean the device is faulty?: It doesn't mean the device is faulty. You can send your vehicle VIN number to our support team; we will check if AutoVIN function supports your vehicle. If not available yet, you can manually select the vehicle model to diagnose, normal functions won't be affected. Our R&D team will add your VIN information into the database and release relevant updates later.
• DTCs can be read normally but fail to be cleared or reappear after clearance, why?: Please keep ignition on and engine off. Record freeze frame data first before clearing codes. Persistent hardware faults need physical repair prior to code clearance. Some fault codes of systems like SRS and ABS can only be cleared after finishing bidirectional tests.
• The device turns on but cannot establish a diagnostic connection. What should I do?: Please verify your vehicle model and production year. POR V4.0 supports Porsche models manufactured from 1996 to 2025. Certain service functions for 2024 vehicles are still being optimized. Disable the vehicle power-saving mode and update your firmware and software to the latest version.

Choose the iCarsoft POR V4.0 for advanced Porsche diagnostics, active component testing, and a wide range of maintenance and service functions in one device. With lifetime free software updates and support for two additional vehicle make groups, it offers flexible diagnostic capabilities without annual software subscription fees. Please check your vehicle's model, production year, and required diagnostic functions for compatibility before purchasing.
