GANGLE TPMS Tire Pressure Sensors User Manual for BMW Models

1. Introduction to TPMS

The Tire Pressure Monitoring System (TPMS) is a safety feature designed to monitor the air pressure inside the pneumatic tires on various types of vehicles. These sensors continuously monitor tire pressure and transmit data to the vehicle's onboard computer, alerting the driver to under-inflated tires, which can lead to unsafe driving conditions, increased fuel consumption, and premature tire wear.

This manual provides detailed instructions for the installation, relearn procedures, and maintenance of GANGLE 433MHz TPMS Tire Pressure Sensors, specifically designed for compatible BMW models including X5 [E70], X6 [E71], Z4 [E86], and 3-Series [E90], [E60] Alpina from 2005-2011.

1.1 Why TPMS is Important

TPMS plays a crucial role in vehicle safety and performance:

• Safety: Prevents accidents caused by under-inflated tires, which can lead to tire failure, loss of control, and increased braking distances.
• Fuel Efficiency: Properly inflated tires reduce rolling resistance, leading to better fuel economy.
• Tire Longevity: Maintains optimal tire pressure, extending tire life and reducing wear.
• Environmental Impact: Improved fuel efficiency contributes to reduced CO2 emissions.

1.2 How Direct TPMS Works

Direct TPMS uses sensors mounted inside each tire to directly measure tire pressure and temperature. This data is then transmitted wirelessly to a receiver in the vehicle. If the system detects low tire pressure or a malfunction, it triggers the TPMS indicator light on the dashboard. The dashboard indicator can be a solid light for low pressure or a flashing light for a system malfunction.

For a visual explanation of TPMS functionality and indicator lights, please refer to the diagrams in the full User Manual (PDF).

2. Safety Information and Warnings

WARNING:

Read all instructions and warnings, and review all illustrations before installing. Professional installation is required. These Tire Pressure Monitor System (TPMS) sensor assemblies are replacement or maintenance parts for motor vehicles that have a factory-installed TPMS only. Failure to follow installation instructions may result in the failure of the motor vehicle TPMS sensor to operate properly.

CAUTION:

• Each TPMS sensor is designed and manufactured to operate in specific motor vehicle makes, models, and years using the proper frequencies (e.g., 433MHz) to communicate with the vehicle's TPM System. Only install TPMS sensors designated for your specific vehicle.
• Improper TPMS installation or the use of unauthorized TPMS sensors will cause the vehicle's TPM System to fail to operate properly.
• Do not install TPMS sensors in damaged wheels.
• Upon completion of installation, test the vehicle's TPM System using procedures described in the original manufacturer's service guide to confirm proper installation. If the TPM system fails to operate properly, check all installation procedures and retest. If the TPM System continues to fail, consult technical support or an authorized motor vehicle dealership.
• These TPMS sensor assemblies are designed and manufactured to operate in Original Equipment wheels and tires only. If non-Original Equipment wheels and/or tires are used, the TPM system and the low tire inflation warning threshold may not function or may function incorrectly. The vehicle owner assumes sole responsibility for TPMS and vehicle function if non-Original Equipment wheels and tires are used.
• Failure to follow installation instructions or the use of improper TPMS sensors may result in motor vehicle TPM system failure, causing property damage, personal injury, or death.

3. Installation Instructions

This section outlines the steps for removing old TPMS sensors and installing new ones. It is crucial to follow these steps carefully to ensure proper function and safety. For detailed diagrams and visual guidance, please refer to the full User Manual (PDF).

3.1 Clamp-in Sensor Removal Overview

The following steps detail the process for replacing clamp-in type TPMS sensors. Always use appropriate tools and exercise caution.

1. Remove Valve Core: Remove the valve core to allow all air to escape from the tire. Discard the old valve core.
2. Remove Mounting Nut: If removing a clamp-in sensor before dismounting the tire, remove the mounting nut from the stem and allow the sensor to fall into the wheel/tire assembly. Discard the old nut.
3. Break Tire Bead: With the sensor removed (or if installed, ensure it's positioned safely), bounce the wheel/tire to ensure the sensor has fallen free. Break the bead free from the rim on the shallow side first, then from the deep side.
4. Sensor Position (if installed): If a sensor is installed, locate it and mark its position on the tire. Position the tire/wheel assembly so the sensor is at the 6 and 12 o'clock positions at all times when breaking the bead to avoid damage.
5. Dismount Tire: Liberally lubricate the bead. Position the wheel assembly such that the mount/demount head is slightly ahead of the sensor (or the mark on sidewall if band-mounted). The tire should dismount without coming in contact with and causing damage to the sensor when removing the bottom bead.
6. Inspect Sensor: Remove the sensor and inspect for evidence of damage or tire sealants. If the sensor is to be re-installed, clean it thoroughly to a dry, clean location.

3.2 Installing a New Clamp-in Sensor

7. Snap-in Sensor Removal (if applicable): For snap-in sensors, remove the T-10 screw from the back of the sensor using a 20140 tool, then using a standard TTV tool pull the old rubber valve stem through the hole. Discard.
8. New Components: When installing a clamp-in sensor, always use a new grommet, mounting nut, special nickel-plated valve core, and sealing cap. NEVER RE-USE OLD COMPONENTS.
9. Insert Sensor: Insert the sensor through the rim hole with the flat side of the sensor facing toward the wheel. Tighten the mounting nut to the specified torque as defined in the Schrader TPMS Application Guide, using the 20142 Mounting Nut Torque Tool.
10. Assemble Snap-in Sensor (if applicable): For snap-in sensors, attach a TTV tool to the valve stem. Insert the valve into the sensor body, aligning the flats on the brass stem to the flats on the receiving hole of the sensor body. Use a valve pull tool to prevent the valve from spinning. Use the T-10 tool to assemble the valve to the sensor body before inserting the assembly into the wheel rim hole.
11. Install Sensor into Wheel: To install the sensor into the wheel, use a standard TTV tool to pull the stem straight through the rim hole. To avoid damaging the stem and/or sensor, a rubber mallet or similar device may be placed between the tool and rim flange to ensure the valve is pulled straight.
12. Tire Installation: Position the rim so that the sensor is 90° or 3 o'clock to the right of the mount/demount head. Liberally lubricate the beads of the tire. While the machine is rotating, maintain pressure on the tire between the starting point of the sensor and the mount/demount head to keep the bead of the tire in the drop center of the wheel. This will allow the tire to be installed without damaging the sensor. Note: All tires are mounted with the sensor installed in the wheel.

CAUTION (Valve Core):

DO NOT re-use the removed valve core. Always replace with a new electroless nickel-plated valve core (aluminum stem). Use of non-electroless nickel-plated cores with aluminum valve stems can result in galvanic corrosion and loss of tire pressure. Tighten core with an approved valve core tool to 0.23Nm - 0.56Nm (2 in-lbs. - 5 in-lbs.). Do Not Over-tighten!

4. Vehicle Relearn Instructions

After installing new TPMS sensors, the vehicle's system needs to "relearn" the new sensor IDs. This can typically be done by driving the vehicle or using an OBDII scan tool. For detailed instructions and any specific vehicle requirements, please refer to the full User Manual (PDF).

4.1 Drive Relearn Procedure

This method allows the vehicle to automatically learn the new sensor IDs through driving:

1. Activate the parking brake. Adjust tire pressures to the vehicle's placard pressure.
2. Insert the key, turn the ignition ON (engine off), and then OFF.
3. Exit the vehicle and allow it to sit for 15 minutes.
4. For the system to learn new TPMS sensor IDs, the vehicle must be operated for several minutes at a speed of 15 mph (25 kph) or more.

4.2 OBDII Relearn Procedure (if applicable)

To avoid driving the vehicle, an OBDII relearn is possible with some OBDII TPMS scan tools:

1. Activate the parking brake. Adjust tire pressures to the vehicle's placard pressure.
2. Follow the TPMS scan tool prompts for your specific vehicle application. Trigger the left-front TPMS sensor at the valve stem using the scan tool trigger. Repeat for the remaining sensors in the following order: right-front, right-rear, left-rear.
3. Turn the ignition to ON (engine off). Connect the OBDII cable from the scan tool to the vehicle's OBDII port.
4. When the OBDII connection is made, the scan tool will display that sensor IDs are uploading. This process may take up to 1 minute.
5. If the OBDII procedure fails (not all TPMS scan tools are capable), the vehicle must be driven to complete the relearn process.

5. Maintenance and Best Practices

Regular maintenance and adherence to best practices ensure the longevity and proper functioning of your TPMS. For visual aids on different sensor types and their components, refer to the full User Manual (PDF).

5.1 Step-by-Step Best Practices in TPMS

1. Check for the Light:
   • If the TPMS indicator light illuminates during start-up and then disappears, the system is operational.
   • Solid Light: Indicates one or more tires are 20% below recommended placard pressure. Solution: Add air to meet placard recommendation.
   • Flashing Light: Indicates a dead sensor battery, missing sensor, broken sensor, or an incorrect sensor for the vehicle type. Solution: Replace sensor, relearn sensor.
2. Inspect Valve Caps: A missing or improper valve cap can lead to corrosion and limit the serviceability of a TPMS sensor. Always ensure a sealing valve cap is installed.
3. Check TPMS Sensors: Use a TPMS scan tool to test each installed sensor. This confirms any alerts indicated by the flashing or solid light.
4. Access Vehicle's Computer: Use a TPMS scan tool to check for any Diagnostic Trouble Codes (DTCs) related to the vehicle's TPMS system. This can help identify system faults and view sensor history.
5. Review Audit Report: After service, a detailed "audit report" should be provided, showing the status of the TPMS system and service recommendations.

Note on Sensor Components: Compression forces, high temperatures, and corrosion can damage sensor components. Replace serviceable parts whenever a tire is removed from the wheel to prevent slow tire leaks and frequent TPMS indicator lights.
