What You'll Learn
Volkswagen Golf TPMS systems vary by year
The Volkswagen Golf is equipped with direct and indirect TPMS systems, depending on the manufacturing year. TPMS (Tyre Pressure Monitoring System) technology ensures you stay in full control of your drive, regardless of weather or terrain conditions. All models released since 2006 are required to be fitted with this technology.
For the years 2010-2011, the Volkswagen Golf was manufactured with a direct TPMS system. This system has TPMS sensors installed in the wheel, which transfer information to the vehicle's ECU if one or more tires indicate low tire pressure. When changing air pressure, rotating tires, or replacing a TPMS sensor, a TPMS relearn is recommended.
From 2012-2019, the Volkswagen Golf was manufactured with an indirect TPMS system. This system does not have sensors in the wheels and instead uses the ABS system to communicate when tire pressure is low in one or more tires. Similar to the direct system, a TPMS relearn or re-calibration is recommended when changing air pressure, rotating tires, or replacing a TPMS sensor.
When servicing a Volkswagen Golf, it is important to perform a "CHECK TPM" before working on the vehicle. This will indicate whether the vehicle is manufactured with a direct or indirect system. If the vehicle has an indirect system, an indirect relearn should be performed to turn the TPMS light off.

Direct TPMS systems have sensors in the wheel
The Volkswagen Golf is equipped with direct and indirect TPMS systems, depending on the manufacturing year. Direct TPMS systems have TPMS sensors installed in the wheels of the vehicle. These sensors are usually placed on the inside of the valve, with some systems having them mounted on the outside of the wheel.
Direct TPMS systems directly measure tire pressure using hardware sensors. These sensors are battery-driven and transfer pressure information to a central control unit, which then reports it to the vehicle's onboard computer. This allows the system to warn the driver of under or over-inflation of a tire. Some units also measure and alert the driver of the temperature of the tire.
The sensors in direct TPMS systems are typically equipped with an RF transmitter circuit, which broadcasts the measured pressure within the tire. These sensors are designed to use as little power as possible to maximize battery life. This is achieved by using very low-power circuitry and transmitting data infrequently and with low power.
Direct TPMS sensors are usually fitted to the back of the valve stem on each wheel. They use ultra-high frequency (UHF) radio to transmit data, with frequencies of around 433 MHz in Europe and 315 MHz in other parts of the world. Some systems have separate receivers or antennas near each wheel, while others have a single receiver that receives data from all the wheels.
In contrast, indirect TPMS systems do not have sensors in the wheels. Instead, they use the ABS system to communicate when the tire pressure is low in one or more tires by evaluating wheel speed sensors.

Indirect TPMS systems use ABS to communicate low tire pressure
The Volkswagen Golf is equipped with both direct and indirect TPMS systems, depending on the manufacturing year. An indirect TPMS system does not have sensors installed inside the wheels to monitor air pressure. Instead, it uses the Anti-lock Brake System (ABS) to detect low tire pressure by comparing the relative wheel speeds. When a tire loses air, its diameter decreases slightly, and this change in wheel speed is registered by the ABS wheel speed sensors.
Indirect TPMS systems offer a more affordable option for vehicles already equipped with ABS. However, they are generally less sensitive to changes in tire pressure compared to direct TPMS systems. For example, older indirect TPMS may not activate the warning light if all tires are underinflated by a similar amount. This is because all the tires will be rotating at the same speed, so the system cannot detect a problem.
To address this issue, newer indirect TPMS systems utilize improved wheel speed sensors and modules. These advancements have led to the re-adoption of indirect TPMS in some vehicle models, including Audi, Honda Accord, Mazda CX-5, and select VW Golf platform vehicles.
When servicing a Volkswagen Golf equipped with an indirect TPMS system, it is recommended to perform a TPMS relearn or re-calibration when changing air pressure, rotating tires, or replacing a TPMS sensor. This process ensures that the system accurately monitors tire pressure and alerts the driver if the pressure drops more than 25% below the recommended level, as mandated by federal law.

A TPMS relearn is recommended when changing tire pressure
The Volkswagen Golf is equipped with direct and indirect TPMS systems, depending on the manufacturing year. A TPMS relearn is recommended when changing the tire pressure, rotating tires, and replacing a TPMS sensor.
For Volkswagen Golf models manufactured between 2010 and 2011 with a direct TPMS system, a TPMS relearn procedure is recommended when adjusting tire pressure. This system utilizes TPMS sensors installed in the wheels to detect low tire pressure and transfer this information to the vehicle's ECU.
On the other hand, for Golf models from 2012 to 2019 equipped with an indirect TPMS system, a TPMS relearn or re-calibration is also advised when changing air pressure. The indirect system does not have sensors in the wheels and instead relies on the ABS system to indicate low tire pressure.
Performing a TPMS relearn ensures that the TPMS sensors accurately detect and communicate tire pressure information to the vehicle's systems. This process helps maintain the longevity of the tires, optimizes fuel efficiency, and enhances overall vehicle safety.
There are various methods to initiate a TPMS relearn. One approach involves using a triggering-type relearn tool to prompt the TPMS sensor to announce itself, eliminating the need to manually adjust tire pressure. Alternatively, some vehicles offer a "Relearn Tire Pressure" option on the infotainment screen, which guides you through the process of adjusting the pressure in each tire until the car honks, confirming the completion of the relearn procedure. Additionally, certain vehicles, like the Toyota Tundra, provide a reset button for the TPMS system, allowing for a straightforward reset and relearn process.

A separate set of wheels without TPMS sensors may cause issues
The Volkswagen Golf is equipped with direct and indirect TPMS systems, depending on the manufacturing year. A direct TPMS system has TPMS sensors installed in the wheel, which transfer information to the vehicle's ECU if one or more tires indicate low tire pressure. An indirect system, on the other hand, does not have sensors in the wheels and instead uses the ABS system to communicate low tire pressure.
While there is no legal requirement to use TPMS sensors on a separate set of wheels, it is recommended for safety reasons. TPMS sensors provide valuable information about tire pressure and temperature, which can help prevent accidents caused by underinflated tires. Additionally, some vehicles may have constant warnings and beeps during startup if TPMS sensors are not installed, which can be annoying and distracting.
Furthermore, a separate set of wheels without TPMS sensors may cause issues with the vehicle's ECU. The TPMS sensors are designed to work with the specific make and model of the vehicle, and installing a different set of wheels without sensors may affect the accuracy of the ECU's tire pressure readings. This, in turn, could lead to false alerts or failures to alert the driver of unsafe tire pressure conditions.
In addition, a separate set of wheels without TPMS sensors may impact the functionality of other systems in the vehicle. For example, the TPMS system may be integrated with the stability control or traction control systems, which rely on accurate tire pressure information to function effectively. Without TPMS sensors, these systems may not perform optimally, potentially affecting the overall safety and performance of the vehicle.
While some people choose to manually check their tire pressure and forgo the use of TPMS sensors, it is important to consider the potential consequences. TPMS sensors provide real-time data and alerts, helping drivers maintain proper tire pressure and avoid unsafe driving conditions. While manual checks are still necessary, TPMS sensors offer an additional layer of safety and convenience. Therefore, it is advisable to consult a knowledgeable technician before installing a separate set of wheels without TPMS sensors to ensure compatibility and maintain the overall performance and safety of the vehicle.
