Resetting the Tire Pressure Sensor on BMW 335i
The tire pressure monitoring system (TPMS) in the BMW 335i is designed to alert drivers when tire pressure is low. However, after inflating tires to the recommended levels, the TPMS may still show a warning light. Resetting the sensor is necessary to ensure the system accurately reflects the current tire pressures.
Understanding the Tire Pressure Monitoring System Light
When the TPMS light is flashing, it indicates a problem with the system. This could be due to low tire pressure, a malfunctioning sensor, or a need for recalibration. It’s essential to address the issue promptly to maintain safety and performance.
Steps to Reset the Tire Pressure Sensor
- Check Tire Pressure: Ensure all tires are inflated to the recommended pressure listed in the owner’s manual or on the driver’s side door jamb.
- Turn on the Ignition: Insert the key fob into the ignition and turn it to the “On” position without starting the engine.
- Locate the TPMS Reset Button: This button is usually found under the steering wheel or in the glove compartment.
- Press and Hold the TPMS Reset Button: Hold the button until the TPMS light blinks three times, then release it.
- Start the Engine: Turn the ignition off and then start the engine to complete the reset.

| 4 | Press and hold the reset button. |
| 5 | Start the engine. |
Additional Tips
- Always check tire pressure before resetting the TPMS.
- If the light remains on after resetting, consult a professional mechanic.
- Regularly inspect the tires for damage or wear.
Importance of Maintaining Proper Tire Pressure
Maintaining proper tire pressure is crucial for the overall performance and safety of your BMW 335i. Incorrect tire pressure can lead to various issues, including reduced fuel efficiency, uneven tire wear, and compromised handling. Tires that are under-inflated can overheat, increasing the risk of blowouts, while over-inflated tires can lead to a harsh ride and decreased traction.
Benefits of Proper Tire Pressure
- Improved Fuel Efficiency: Properly inflated tires reduce rolling resistance, leading to better fuel economy.
- Enhanced Safety: Adequate tire pressure ensures optimal grip and handling, reducing the risk of accidents.
- Extended Tire Life: Maintaining the correct pressure helps prevent uneven wear, extending the lifespan of your tires.
- Better Ride Comfort: Proper inflation contributes to a smoother and more comfortable driving experience.
How to Check Tire Pressure
Checking the tire pressure on your BMW 335i is a straightforward process that can be done at home or at a gas station. Regular checks are recommended, especially before long trips or season changes.
Steps to Check Tire Pressure
- Gather Tools: You will need a tire pressure gauge, which can be digital or manual.
- Remove Valve Caps: Unscrew the valve caps from each tire, keeping them in a safe place.
- Measure Pressure: Press the tire pressure gauge onto the valve stem and read the pressure displayed. Make sure to do this quickly to avoid air loss.
- Compare with Recommendations: Check the measured pressure against the recommended levels found in the owner’s manual or on the door jamb.
- Adjust as Necessary: Inflate or deflate the tires to reach the recommended pressure.
- Replace Valve Caps: After checking and adjusting, ensure to put the valve caps back on securely.
Useful Tips for Maintaining Tire Pressure
Maintaining proper tire pressure requires ongoing attention. Here are some useful tips to help you keep your BMW 335i in optimal condition:
- Check Monthly: Regularly check tire pressure at least once a month and before long trips.
- Inspect for Damage: Routinely check tires for signs of wear, punctures, or bulges.
- Use a Reliable Gauge: Invest in a good-quality tire pressure gauge for accurate readings.
- Monitor Temperature Changes: Tire pressure can fluctuate with temperature changes, so check pressure when temperatures drop or rise significantly.
- Seek Professional Help: If you frequently experience pressure loss, consult a professional to check for leaks or sensor issues.
