Diagnostic Steps

1
Check the tire pressure of all four tires using a reliable tire pressure gauge.
2
Inspect the tires for visible signs of damage, such as punctures, cracks, or bulges.

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner, socket set.
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Inflate Tires

If any tire pressure is below the recommended level:
- Locate the valve stem on the tire.
- Remove the valve cap and attach the air hose to inflate the tire to the specified pressure.
- Replace the valve cap securely after inflating.
Repeat for all tires as necessary.

3. Inspect and Replace TPMS Sensors (if needed)

If tire pressure is correct but the light remains on:
- Remove the tire from the wheel using a socket set.
- Locate the TPMS sensor within the tire.
- Inspect the sensor for damage or corrosion.
- If defective, replace with a new TPMS sensor, ensuring it matches the specifications for the Tiguan.
- Reassemble the tire onto the wheel and adjust the torque to the manufacturer's specification.

4. Reset TPMS

After addressing the tire pressures and sensors:
- Start the vehicle and locate the TPMS reset button (usually found under the steering wheel or in the glove box).
- Press and hold the reset button until the TPMS light blinks three times, then release it.
- Drive the vehicle for a few minutes to allow the system to recalibrate.
