- Low Tire Pressure: If one or more tires are under-inflated, the system will trigger a warning. Always check the tire pressure first when the light comes on.
- Sensor Malfunction: The TPMS sensors inside the wheels can wear out over time, especially if the vehicle has high mileage or the tires have been replaced recently.
- Tire Change or Rotation: If the tires have been rotated or replaced, the system may need to reset or recalibrate to correctly detect the pressure.
- Dead TPMS Sensor Batteries: The sensors in your Caddy’s wheels contain batteries that usually last 5-7 years. When these batteries die, they stop transmitting tire pressure data, leading to a fault warning.
- Electrical or Software Glitches: The TPMS in the Caddy can sometimes display an error due to software issues or wiring problems.
Steps to Fix the Tire Pressure Sensor Issue in the Volkswagen Caddy
- Check Tire Pressure:
- Use a tire pressure gauge to make sure each tire is inflated to the correct PSI, which can be found in your vehicle manual or on the driver’s door frame sticker.
- Reset the TPMS System:
- Access the Infotainment System in your Caddy.
- Go to Vehicle Settings.
- Select Tires and then choose Reset Tire Pressure Monitoring to recalibrate the system and clear the fault.
- Check for Faulty Sensors:
- If the reset doesn’t fix the issue, the problem may lie with one of the sensors. Have a mechanic test and replace any faulty sensors if needed.
- Software Update:
- Make sure your Caddy’s software is up to date. Volkswagen regularly releases updates to fix potential bugs that can affect the TPMS.
- Visit a Certified Volkswagen Service Center:
- If the issue persists, visit a Volkswagen service center for a full diagnostic. They can test the system, check the sensors, and resolve any deeper electrical or software issues.
