Audi TPMS Malfunction (Causes, Fixes, and Reset Guide)

audi tpms malfunction

If you own an Audi, you may have encountered the dreaded “TPMS Malfunction” warning on your dashboard. This warning is related to your Audi’s TPMS, or Tire Pressure Monitoring System.

In this comprehensive guide, we will delve into what TPMS is, the possible causes of a TPMS malfunction in your Audi, and provide you with step-by-step instructions on how to resolve and reset this alert.

So let’s get started!

Understanding Audi TPMS

Before we dive into the causes and fixes of a TPMS malfunction, let’s first understand what TPMS is and how it works in your Audi. TPMS stands for Tire Pressure Monitoring System, and it is responsible for monitoring the inflation pressure of your tires.

It detects any sudden changes or if the pressure drops below a pre-set limit. The Audi TPMS consists of tire pressure sensors (TPS) and a TPMS Control Module.

The TPS, located inside each tire, measures the tire pressure and sends this information to the TPMS Control Module, which then displays it on your dashboard.

Types of TPMS Used by Audi

Audi utilizes two types of TPMS: direct and indirect. Most Audi models use the direct type, which means that the system relies on sensors mounted inside each tire to transfer data.

However, it’s worth noting that certain Audi models use an indirect type of TPMS, depending on the year of manufacture.

What Does “TPMS Malfunction” Mean on an Audi?

When you see the “TPMS Malfunction” or “Tire Pressure System Malfunction” message on your Audi dashboard, it indicates that your TPMS system has detected a problem.

This could be due to various reasons, such as issues with the tire pressure sensors, unbalanced tire pressure, or even a faulty TPMS control module.

Common Causes of Audi TPMS Malfunction

  1. Faulty Tire Pressure Sensor(s): One of the most common causes of a TPMS malfunction in an Audi is a failure of one or more tire pressure sensors. These sensors transmit tire pressure information to the TPMS control module. Various factors such as a bad TPS battery, exposure to extreme temperatures, valve stem corrosion, wear and tear, or physical damage can lead to sensor failure.
  2. Unbalanced Tire Pressure: Another common cause of a TPMS malfunction is unbalanced tire pressure. If one or more tires have significantly lower or higher pressure than the others, it can cause issues with the TPMS system. This often occurs when switching to aftermarket tires that are not calibrated for the Audi TPMS system.
  3. Bad ABS Sensors: In Audi models that use an indirect TPMS system, a combination of wheel speed sensors and ABS sensors is used to determine if a tire has lost pressure. If any of these components fail, it can trigger a TPMS malfunction warning.

Fixing and Resetting “TPMS Malfunction” on an Audi

Now that we have identified the common causes of a TPMS malfunction, let’s discuss how to resolve and reset this issue in your Audi.

Resetting the TPMS System

  1. Disconnect the Battery: In some cases, disconnecting the battery and reconnecting it can resolve the TPMS malfunction. This may reset the system and clear any temporary issues. However, if the issue persists, further troubleshooting is required.
  2. Check Tire Pressure: Ensure that all tires are properly inflated to the recommended PSI. Use a tire pressure gauge to measure the pressure and inflate or deflate them as needed. The recommended PSI can usually be found on a sticker located on the driver’s door jamb or in the owner’s manual.
  3. Replace Faulty Tire Pressure Sensors: If the TPMS malfunction persists, it may be necessary to replace the faulty tire pressure sensors. Consult your Audi dealer or a reputable tire service center to identify the specific sensors that need replacement. They can also help you with the installation and programming of the new sensors.

Seeking Professional Assistance

If the above steps do not resolve the TPMS malfunction in your Audi, it is recommended to seek professional assistance.

A certified Audi technician or a specialized tire service center with the necessary diagnostic tools and expertise can accurately diagnose and fix the issue.
