Replace tire valve cores on the Volkswagen Eos
Adjust air in all tires before resetting the TPMS
By: Information provided by Mitchell 1
SUBJECT VEHICLE: 2007-10 Volkswagen Eos
RESET PROCEDURE? Yes. Directions follow.
SPECIAL TOOLS NEEDED? No.
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.
