Solution

1. Prepare for Repair

Gather all necessary tools and replacement parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Wear safety gloves and goggles.

2. Inflate Tires

Tools Required: Tire pressure gauge, air compressor.
Check the current tire pressures of all four tires.
Inflate each tire to the manufacturer’s recommended pressure (usually found on the driver’s door jamb).
Re-check the pressures after inflating to ensure they are correct.

3. Inspect and Repair Tires

Tools Required: Tire repair kit (if applicable), jack and jack stands.
If any tire appears damaged or has a puncture:
- Loosen the lug nuts and lift the vehicle using a jack.
- Remove the wheel and inspect the tire for punctures or cracks.
- If a puncture is found, follow the tire repair kit instructions to seal it.
- If the tire is severely damaged, replace it with a new one.

4. Reset TPMS

Tools Required: OBD-II scanner (if needed).
Turn on the vehicle ignition without starting the engine.
Locate the TPMS reset button (usually under the steering column) and press it until the TPMS light blinks and goes off.
If the vehicle does not have a reset button, follow the instructions in the owner’s manual to reset via the iDrive system.

5. Test Drive

After resetting, drive the vehicle for a few miles to allow the TPMS to recalibrate.
Monitor the TPMS light to ensure it remains off.
