Solution

1. Preparation

Ensure that the vehicle is parked on a level surface.
Gather the necessary tools: TPMS scan tool (if required), tire pressure gauge.

2. Inflate Tires

Use a tire pressure gauge to check the tire pressure of all four tires.
Inflate or deflate tires as needed to match the recommended pressure.

3. Reset TPMS

Turn the ignition to the "On" position without starting the engine.
Press the TPMS reset button, which is typically located under the steering column or in the glove compartment, until the TPMS warning light blinks three times.
If the vehicle is equipped with the PCM (Porsche Communication Management) system, navigate to "Settings" > "Tires" > "TPMS" and select "Reset."

4. Test the System

Start the engine and drive the vehicle for a few minutes at speeds above 20 mph to allow the system to recalibrate.
Observe if the TPMS warning light turns off after driving.
