Frequently asked questions
Still deciding?
Is the software updated regularly? Are updates free?
Yes! The iCarsoft VAWS V4.0 includes lifetime free software upgrades via Wi-Fi. There are zero annual subscription fees or hidden costs. You pay once and get continuous software updates forever.
What's the difference between VAWS V4.0 and the older VAWS V3.0?
VAWS V4.0 is the update version of VAWS V3.0. Vehicle make coverage expansion: VAWS V4.0 enables users to download two extra vehicle make groups. Hardware upgrade: VAWS V4.0 features upgraded hardware (5-inch touchscreen, Android OS, Quad-Core processor, 64GB storage, 5000mAh battery).
The VAWS V4.0 cannot recognize my vehicle by AutoVIN, does it mean the device is faulty?
Not at all. AutoVIN depends on individual vehicle ECU protocols. If AutoVIN skips your car, simply use the Manual Selection mode — all diagnostic and service functions will work perfectly. Meanwhile, please send your VIN to our support team; we will verify it and add it to our database in the next software update.
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 scanner powers on but fails to establish a diagnostic connection. What causes this issue?
Check vehicle compatibility — ensure your vehicle belongs to the V.A.G group (1996–2025) or one of your 2 downloaded vehicle make groups. Disable any eco/battery-saving modes on the vehicle that might shut down modules during diagnosis. Connect to Wi-Fi and update both the firmware and vehicle software to the latest versions. Ensure the vehicle key is turned to the "ON" position.
Does the VAWS V4.0 work on my Volkswagen Golf?
Yes, absolutely! The VAWS V4.0 offers deep, dealer-level diagnostic coverage for the entire Volkswagen lineup across all major production years.
