How to eliminate the tire pressure monitor light on Jetta
Recently, the issue of the tire pressure monitoring light on Jetta models has become the focus of heated discussion among car owners. Many car owners reported that the tire pressure warning light on the vehicle dashboard suddenly came on, but no obvious abnormalities were found after checking the tires. This article will combine the hot discussions and professional technical advice on the Internet in the past 10 days to provide you with a detailed analysis of the possible causes and elimination methods of the Jetta tire pressure monitor light.
1. Common reasons why the Jetta tire pressure monitoring light is on
Cause classification | Specific instructions | probability of occurrence |
---|---|---|
Abnormal tire pressure | The air pressure of one or more tires is more than 20% lower than the standard value | 45% |
Effect of temperature changes | The temperature difference between day and night causes tire pressure fluctuations exceeding the monitoring threshold | 25% |
Sensor failure | The tire pressure sensor battery is exhausted or the signal transmission is abnormal. | 15% |
System false alarm | Sporadic false alarms in electronic systems | 10% |
other reasons | Failure to reset the system after tire replacement, wheel speed sensor failure, etc. | 5% |
2. Step-by-step method to eliminate the tire pressure warning light
1.basic check
Use a tire pressure gauge to measure the pressure of all tires (including the spare tire), and adjust according to the standard value marked on the door frame. It is recommended to measure with cold tires (parked for more than 3 hours).
2.System reset operation
model year | Reset method | Things to note |
---|---|---|
2016-2019 models | Ignition switch ON → long press the central tire pressure SET button for 3 seconds → hear the prompt sound | Need to operate when the vehicle is stationary |
2020 models and later | Via MIB infotainment system: Vehicle → Settings → Tire Pressure → Reset | Some models require 10 minutes of driving to complete self-learning. |
3.Handling special situations
If the light still does not go out after adjusting the tire pressure, it is recommended to drive at a constant speed of 40-60km/h for 15-20 minutes to allow the system to re-detect the tire status. Some models require this learning process to eliminate the alarm.
3. Professional solutions for repair stations
Fault type | Professional testing methods | solution | Estimated cost |
---|---|---|---|
Sensor failure | Special diagnostic instrument reads sensor ID signal | Replace the corresponding wheel sensor | 300-500 yuan/piece |
System program issues | ODIS detection control unit software version | Refresh TPMS control unit program | 100-200 yuan |
Line failure | Measuring sensor to receiving module line | Repair wiring harness or plug | 200-400 yuan |
4. Effective tips tested by car owners
According to recent discussions on car owner forums, the following methods have been proven to be effective for some models:
• Disconnect the negative terminal of the battery and reconnect it after 5 minutes to reset the vehicle electronic system
• Press and hold the SET button and hazard alarm flash button simultaneously for 10 seconds
• With normal tire pressure, complete 3 consecutive sudden stops (safe road section)
5. Prevention Suggestions
1. Check tire pressure at least once a month, pay special attention when the seasons change.
2. Be sure to check the tire pressure status before driving long distances
3. Pay attention to protecting the tire pressure sensor when replacing tires
4. Use tires with specifications specified by the original manufacturer to avoid modifications that affect monitoring accuracy.
It should be noted that some Jetta models produced after 2021 use a new generation of indirect tire pressure monitoring system (iTPMS). Its working principle is different from traditional direct monitoring. Please refer to the vehicle manual for the reset method. If the warning light cannot be eliminated after several attempts, it is recommended to go to an authorized service station for professional inspection in time to avoid affecting driving safety.
