iCarsoft POR V4.0 car diagnostic tool is equipped with a 5-inch Ultra 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 POR 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 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.
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.

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.
Evaluates the battery charge state, monitors closed-circuit current, registers battery replacement, and activates the vehicle's sleep mode.
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.
