01521 - Sensor for Tire Pressure
01521 - Sensor for Tire Pressure: Lower Limit Exceeded
Possible Symptoms
- Malfunction Indicator Light (MIL) active
Possible Causes
- Tire Pressure too Low
- Tire Pressure Sensor(s) not installed
- Winter Tires without Sensors
Possible Solutions
- Check Tire Pressure
- Check/Install Tire Pressure Sensors
01521 - Sensor for Tire Pressure: No Signal/Communication
Possible Symptoms
- Malfunction Indicator Light (MIL) active
Possible Causes
- Tire Pressure Sensor(s) faulty
- Tire Pressure Sensor(s) not installed
Possible Solutions
- Check/Install Tire Pressure Sensors
- Check individual Sensors via Measuring Value Blocks (MVB)
Special Notes
- On Systems without Position Recognition (e.g. Golf/Jetta (1K) or Passat (3C)) raise or lower the Pressure for one Tire after the other and double check the Measuring Value Blocks (MVB) 001-012 (and 016) for changes. If you can determine no Change in the Measuring Value Blocks (MVB) after raising/lowering the Pressure you have most likely found the faulty Sensor.
- Note: It may take up to 2 minutes until the Pressure Change is being displayed in the Measuring Value Block (MVB). To locate the individual Wheels it helps to note the Sensor Identification Number.
