Vehicle Groups Available for Selection
PICK ANY 2 · FREE OF CHARGEIt doesn’t just read codes — it commands your car.
The VAWS V4.0 doesn't just read codes—it talks directly to your car. This professional-grade scanner sends active commands straight to individual vehicle modules and watches them respond in real time, bypassing the cabin switches entirely.
Body & Comfort Active Tests
Imagine a power window won't roll up. Is it a broken door switch, a blown fuse, or a dead motor? Instead of ripping apart the door panel to test wires, you just tap the screen on your VAWS V4.0. If the window rolls down, you know the motor is perfectly fine and the switch is the culprit. No more guesswork, no more buying parts you don't need.
- Command Window Regulators: Drive windows up and down straight from the scanner to isolate bad switch clusters in seconds.
- Trigger Door Locks & Side Mirrors: Actuate locks and mirrors on demand to pinpoint body control module glitches.
Powertrain & Fuel Active Tests
Send commands straight to the engine-side modules and watch each component respond in real time — no cabin switches, no waiting for the fault to reappear.
- Kick On the Fuel Pump: Activate the fuel pump instantly to verify fuel pressure dropping issues.
- Modulate Throttle Opening: Sweep the throttle to check for sticking carbon deposits.
Chassis & Brake Active Tests
Take direct control of the hydraulic hardware that normally only responds while driving — essential for a proper brake service.
- Cycle the ABS Pump Motor: Run the pump on command to purge trapped air during brake bleeding.
Dynamic Output Tests
Beyond the headline tests, the VAWS V4.0 can exercise nearly every electrically driven component on the car.
- Any Actuator or Solenoid: Run dynamic output tests on virtually any onboard actuator or solenoid in minutes.
- Confirm Before You Buy: Watch the module respond live and confirm the failed part before ordering a replacement.
Recode and personalize — the way a dealer would.
Engineered for ultimate precision, the VAWS V4.0 delivers extensive ECU coding capabilities for major VAG models from 2010 onward. (Full-system diagnostics and service functions cover models from 1996 to 2025.) To ensure a seamless user experience, it features a dedicated, standalone [Coding] function menu built directly into the diagnostic software for quick, intuitive access—eliminating complex navigation and putting dealer-level customization right at your fingertips.
Code the ECU based on your vehicle's factory or custom attributes, including body style, trim variant, steering wheel position (LHD/RHD), and fuel type.
Write original vehicle configuration data into a newly replaced ECU module, seamlessly resolving faults caused by coding mismatches.
- Modify country/regional coding settings.
- Change vehicle brand identifiers within the system.
- Update and refresh the vehicle's ECU installation list.
- Adjust daytime running lights (DRL) switching logic.
- Customize automatic central locking timing and preferences.
A 5-inch Android tablet built to run all day in the bay.
iCarsoft VAWS V4.0 car diagnostic tool is equipped with a 5-inch HD Touch Screen, Android operating system, Quad Core 1.3 GHz processor, 32GB memory and a 5000mAh battery for around 6 hours of continuous use. It offers a user-friendly interface and an ultra-smooth diagnostic experience.
Pay once. Upgrade forever — no subscription, ever.
Unlike other OBD scan tools on the market that require annual subscription fees, the VAWS V4.0 offers lifetime free software upgrades. Updates are delivered wirelessly via Wi-Fi, with new diagnostic protocols and vehicle model coverage continuously released.
UPDATE PLANReady for the newest V.A.G group communication standard.
CAN-FD (Controller Area Network – Flexible Data-rate) is a next-generation automotive communication protocol adopted by Audi / Bentley / Bugatti / Lamborghini / SEAT / Skoda / VW / VW Commercial Vehicles / VW LT3 / MAN Light-Duty.
What is CAN-FD?
CAN-FD (Controller Area Network – Flexible Data-rate) is the next-generation evolution of the classic CAN bus, now adopted across the newest V.A.G group platforms.
- Flexible Data-Rate: Transfers larger data frames at faster speeds than classic CAN, keeping up with modern vehicle electronics.
- The New Factory Standard: Adopted by the V.A.G group on the latest platforms.
CAN-FD Ready, Out of the Box
- Native CAN-FD Support: Talks the CAN-FD protocol directly from the standard OBD2 port.
- Newest Models Covered: Keeps the VAWS V4.0 connected to the latest V.A.G group chassis in its coverage range.
One Tool, Every Protocol
CAN-FD is only the newest layer — the VAWS V4.0 speaks the full range of protocols used across decades of V.A.G group models.
- Beyond CAN-FD: Also supports classic CAN, K/L-Line and the other factory protocols listed in the full specifications below.
- Old or New, One Tool: From early CAN models to today's CAN-FD platforms, the VAWS V4.0 selects the right protocol for the car.
Plug in. Your VAG vehicle names itself in seconds.
Skip the manual VIN typing — simply plug in, and the tool identifies your vehicle in seconds. No typos, no extra lookup time. This boosts accuracy, eliminates input errors, and delivers a smoother, more reliable diagnostic experience.
One-Plug Identification
- Automatic VIN Read: Simply plug into the OBD2 port and the VAWS V4.0 identifies your vehicle in seconds.
- No Extra Lookup Time: Skip manual VIN typing and model-menu digging entirely — go straight to diagnostics.
Accuracy Built In
- Eliminates Input Errors: No typos means the scanner always loads the exact software profile for your vehicle.
- Smoother, More Reliable Sessions: Correct identification from the first second delivers a more reliable diagnostic experience.
Manual Selection Backup
AutoVIN depends on individual vehicle ECU protocols. If AutoVIN skips your car, it doesn't mean the device is faulty — you always have a second way in.
- Manual Selection Mode: Pick your model from the menu and every diagnostic and service function works exactly the same.
- Growing VIN Database: Send your VIN to the support team and it will be verified and added in the next software update.
Diagnose in your language, wherever you wrench.
V.A.G scanner VAWS V4.0 supports English, German, French, Dutch, Spanish, Czech, Swedish, Russian, Hungarian, Norwegian, Portuguese, Italian, Polish, Danish, and Finnish.
