Ready for the newest Porsche platforms on the road.
CAN-FD (Controller Area Network – Flexible Data-rate) is the next-generation communication protocol that Porsche has adopted across its latest platforms.
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 Porsche 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 Porsche 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 POR V4.0 connected to the latest Porsche chassis in its coverage range.
One Tool, Every Protocol
CAN-FD is only the newest layer — the POR V4.0 speaks the full range of protocols used across decades of Porsche 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 POR V4.0 selects the right protocol for the car.
Stop guessing — command every component and watch it answer.
Ordinary OBD scanners only read fault codes — they tell you what might be wrong, but not which part is actually failing. The POR V4.0 goes further: full bidirectional control lets you send commands directly to individual components and watch them respond in real time.
Body & Comfort Active Tests
Command body and comfort modules directly from the screen and isolate a bad switch, motor or module in seconds — no door panels off, no wire probing.
- Windows, Locks, Mirrors & Sunroof: Test window regulators, door locks, mirrors, and sunroof motors module by module.
Powertrain & Fuel Active Tests
Send commands straight to the engine-side modules and watch each component respond in real time — before touching a single part.
- Activate the Fuel Pump: Verify fuel pressure before tearing down the rail.
- Command Throttle Body Opening: Diagnose idle and acceleration faults on demand.
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: Bleed each wheel circuit individually, on command.
Dynamic Output Tests
Identify the faulty part in minutes — not days of trial-and-error part-swapping.
- PDK, PASM & PCM Actuator Tests: Run actuator tests on the PDK transmission, PASM dampers, and PCM infotainment modules.
- Almost All Onboard Modules: Output tests reach virtually any electrically driven component on the car.
Plug in, and your Porsche introduces itself.
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 POR 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.
Porsche scanner POR V4.0 supports English, German, French, Dutch, Spanish, Czech, Swedish, Russian, Hungarian, Norwegian, Portuguese, Italian, Polish, Danish, and Finnish.
Far more than a code reader — a full service toolkit.
The POR V4.0 is far more than a basic code reader. It integrates 9 commonly-used service functions for daily maintenance and 19 advanced professional functions for complex repair tasks — 28 in total.
Allows you to reset the engine oil life system, service lamp, service mileage, and service intervals after an oil change.
Relearns throttle valve control parameters after resetting or replacing the throttle body.
Retracts the electric parking brake calipers and resets the brake pads after replacement.
Calibrates the steering wheel to the straight-ahead position, or recalibrates the SAS after steering component replacement.
Performs DPF regeneration, component replacement initialization, and DPF relearning after engine control unit replacement — for diesel particulate filter systems.
Relearns the injector control parameters when an injector is renewed or replaced.
Bleeds air from the system to restore ABS brake response, or performs a relearn procedure after ABS replacement.
Supports calibration, height adjustment, system reset, and fault code clearing for air suspension systems. Lets you precisely set ride height, perform system initialization, and resolve common air suspension faults.

Allows you to look up the tire sensor IDs from the vehicle's ECU, inputting TPMS sensor replacement IDs and testing sensors.
Supports routine maintenance of A/C modules, including A/C system adaptation reset, compressor reset, compressor break-in, and stepper motor initialization.
Calibrates and initializes the adaptive headlamp system (AFS/Matrix LED) — required after headlight assembly replacement, level sensor adjustment, or front suspension repair. Essential for Porsche models equipped with Dynamic Light System or LED Matrix headlights.
Supports routine maintenance of DSC modules, including resetting or deleting adaptation values, and initializing the unit.
Supports routine maintenance of engine modules, including resetting or deleting adaptation values, and calculating fuel consumption.
Supports routine maintenance of transmission modules, including resetting adaptation values and transmission fluid level adaptation.

- Read ECU Information: View each control module's identification details for accurate servicing and part matching.
All-Module Access
Full-system coverage means the POR V4.0 doesn't stop at the powertrain — it reaches the complex body, chassis and driver-assistance modules too.
- Access All ECU Modules via OBDII-16 DLC: Reach every module on the vehicle through the standard 16-pin diagnostic connector.
- Beyond the Big Four: Diagnostic coverage extends past Engine, ABS, Airbags and Transmission into more complex vehicle systems.
