Problem Statement

Learn how to diagnose and fix the persistent tire pressure warning light on your Volkswagen Golf MK7 (2015-2019). Step-by-step guide with tools and tips.

Affected Component

Tire Pressure Monitoring System

Estimated Time

1-2 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a stable surface before jacking.
•Always wear safety glasses when working with tires.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Possible fluctuations in tire pressures
•Uneven tire wear observed during inspection
•Vehicle may pull to one side while driving
•Reduced fuel efficiency

Diagnostic Steps

1
Check the tire pressures of all four tires using a tire pressure gauge.
2
Inspect the tire condition for visible damage or signs of punctures.
3
Use a VAG-COM or OBD-II scanner to check for any fault codes related to the tire pressure monitoring system (TPMS).
4
Verify that the TPMS sensors are functioning properly by checking for sensor signal transmission.
5
Reset the TPMS system using the vehicle's onboard settings or a diagnostic tool after verifying tire pressures.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is off.
Ensure all tires are cold for an accurate pressure reading.

2. Check and Adjust Tire Pressures

Sub-steps:
- Use a tire pressure gauge to measure the pressure in each tire.
- Refer to the vehicle’s door jamb or owner’s manual for the recommended tire pressure.
- Inflate or deflate tires as needed to reach the recommended pressure.

Tools Required:

Tire pressure gauge
Air compressor or tire inflator

3. Inspect and Repair Tires

Sub-steps:
- Visually inspect each tire for any punctures, cuts, or deformities.
- If any damage is found, repair or replace the tire as necessary.
- Check for uneven wear patterns and assess the need for wheel alignment.

Tools Required:

Tire repair kit (if applicable)
Jack and jack stands (if tire removal is necessary)

4. Check TPMS Sensors

Sub-steps:
- Remove the tire if needed to access the TPMS sensor.
- Inspect the sensor for any physical damage.
- If sensors are defective, replace them with OEM parts.

Tools Required:

Torx or socket set (for removing tires)
Replacement TPMS sensors

5. Reset the TPMS

Sub-steps:
- Turn the ignition to the "ON" position without starting the engine.
- Using the vehicle's infotainment system, navigate to the settings menu.
- Select the option to reset the tire pressure monitoring system.

Tools Required:

Vehicle owner's manual (for reference)
