Metal Valve Body, Removing And Installing

WARNING: This page does not describe the selected car, but rather 18 other vehicles, including the 2016 Audi S4, 2016 Audi A4 Quattro, 2016 Audi A4, 2015 Audi S4, and 2015 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

Special tools and workshop equipment required

Torque Wrench 1410 VAG1410

-- Place metal valve with rubber seal through rim from inside.

-- Attach chamfered washer and union nut from outside and tighten by hand.

-- Tighten the union nut.

NOTE:

Be careful not to scratch off the glued- on wheel trim on these rims.

The surface of the wheel trim is very sensitive.

The rim will have be replaced if the wheel trim is damaged.

The wheel trim cannot be replaced.

TPMS + indirect measuring. There are no wheel electronics installed inside the wheel. With the help of the ABS sensors, the TPMS compares the speed and rolling circumference of the individuals wheels. The loss of pressure is determined indirectly. If there is a change in the tire pressure, then the speed and the rolling circumference of wheel will also change.

⁽²⁾	TPMS direct measuring. The wheel electronics are installed inside the wheel on the metal valve; the tire pressure and temperature values are transmitted and evaluated periodically.

All Other Models: 4 Nm

TPMS indirect measuring. There are no wheel electronics installed inside the wheel. With the help of the ABS sensors, the TPMS compares the rolling circumference of the individual wheels. The loss of pressure is determined indirectly. If there is a change in the tire pressure, then the speed of the tire will also change.

-- Secure against turning with counterhold -1- (for example, a 2 mm drill bit).
