Replace tire valve cores on the Volkswagen Eos

Dec. 21, 2011

SUBJECT VEHICLE: 2007-10 Volkswagen Eos

RESET PROCEDURE? Yes. Directions follow.


On 2007-10 Volkswagen Eos vehicles, the tire pressure monitoring system (TPMS) utilizes air pressure sensors in the wheels. The sensors transmit radio data signals to the Central Locking and Antitheft System antennas. These signals are then directed to the TPMS Control Module, which is integrated with a diagnostic address in the Comfort System Central Control Module.

The system checks the tire pressures of all four road wheels, and warns in the event of a loss of pressure by means of symbols in the instrument cluster displays. A visual and audio warning will signal a rapid loss of pressure while the vehicle is moving. The system uses sensors at the wheels, which are integral parts of the air valves.

To remove an old sensor, follow these steps. CAUTION: Replace the valve core each time the tire is changed. Use only original valve inserts from the manufacturer, as they have a special coating.

1. Remove the tire and wheel assembly from the vehicle. CAUTION: Use only original valve caps from the manufacturers. Do not use Comfort valve caps and metal caps.

2. Unscrew the union nut. See Figure 1.

3. Remove the tire pressure sensor from the rim well.

To install a new sensor, follow these steps.

1. Install a new sealing ring and washer on the tire pressure sensor. Insert the sensor and press it into the disc wheel (rim).

2. Install the union nut.

3. Press the tire pressure sensor onto the rim well, and tighten union nut to 71 in. -lbs. (8 N.m.). This will cause the sealing washer to become slightly deformed.

4. Install the tire and wheel assembly to the vehicle.

5. Adjust inflation pressures of all tires, and balance. Store the new tire pressures in the system.


Get ready, set... reset!

Now you are ready to perform reset procedures. NOTE: Whenever a wheel is changed or replaced, or whenever a vehicle has been loaded, the TPMS needs to be reset.

When the low tire pressure warning light comes on, immediately check the air pressure of all tires and adjust to the specified pressure. Then, reset the TPMS. CAUTION: Do not reset TPMS until all problems are fixed and tire pressures in all tires have been adjusted. If the reset procedure is done when tire pressures are incorrect, the TPMS will not work properly and may not set an alert when a tire pressure is low or high.

1. Set the tire pressure of all wheels to the specified pressure.

2. With the vehicle stopped and the parking brake applied, turn the ignition switch to the ON position.

3. Press the SET button (located near the gear shift) until an audio signal is heard. The signal confirms the basic setting.

To reset the TPMS after a wheel or pressure change:

 1. Set the tire pressure of all wheels to the specified pressure.

2. With the parking brake applied, allow the vehicle to stand for 20 minutes so that the control module enters the learning mode. NOTE: An acceleration data check also occurs with vehicle speed. This process takes about seven minutes.

3. Drive the vehicle at 16 mph or more. As soon as the vehicle reaches this speed, tire pressure sensor IDs are automatically recognized and read by the control module.

To reset the TPMS on wheel sets with different pressure specifications, follow these steps. NOTE: If unapproved wheel/tire combinations are installed, a second wheel set must be learned.

To perform this procedure, Volkswagen VAS 5051B is required.

1. Read out the tire pressure sensor IDs before installation.

2. Switch TPMS to the second wheel set.

3. Enter the needed specified tire pressures and sensor IDs into the system.
