WHEELS AND TIRES
Refer to the General Information .
TIRE PRESSURE MONITORING SYSTEM, INDIRECT SYSTEM
Tire pressure monitoring is a system that detects slow to moderate reductions in tire pressure at a wheel position. With the help of the ABS sensors, the TPMS compares the speed and rolling circumference of the individuals wheels. If the rolling circumference changes, the tire pressure monitoring indicator in the instrument cluster lights up and a warning tone is heard. On vehicles with a center instrument cluster display, the location of the tire is given.
After changing from run-flat tires (SST) to non-run-flat tires or vice versa the control module must be recoded.
The rolling circumference of the tire can change if
- The tire pressure is too low.
- The tire has structural damage.
- The vehicle is loaded on one side.
- The tires on one axle are loaded more heavily (e.g. when towing a trailer or driving up and down inclines).
- The spare tire is installed.
- One wheel per axle was changed. (also if exchanging the tires from front to rear or vice versa).
System Malfunction in TPMS
A system malfunction is stored in the Tire Pressure Monitoring Control Module 2 -J793- and indicated by the constant yellow TPMS lamp in the instrument cluster. The TPMS lamp cannot be turned off by pressing the TPMS button. If there is a DTC memory entry, connect -VAS- -5051 and select "Guided Fault Finding" => .
Perform Calibration: (Readapt Tire Pressure)
After each change to the tires, the tire pressure monitoring system button -- in the center console must be pressed while the ignition is switched on and the vehicle is still until the TPMS lamp in the instrument cluster blinks several times. Blinking several times confirms the calibration procedure and the readapting of the tire pressures.
TIRE PRESSURE MONITORING SYSTEM, DIRECT SYSTEM
Observe notes about usage in your Owner's Manual.
The tire pressure monitoring system monitors the pressure of the four tires while driving.
Damaged tire pressure sensors should be replaced for safety reasons.
Do not clean tire pressure sensors with steam blasting or strong compressed air.
For safety reasons, the tire pressure monitoring sensor should be replaced and the rim cleaned after using tire sealant.
The tire pressure monitoring system consists of a control module, a central antenna integrated in the control module and one tire pressure sensor in each of the four wheels.
If wheel positions on the vehicle are changed, tires are changed, tire pressure sensors are replaced or pressures are changed, control module must be readapted.
Note. When changing a tire with tire pressure monitoring sensors (summer/winter tires), tire pressure must be checked and the sensor readapted to the control module.
A fault may be saved in the DTC memory if
There is a system malfunction.
When installing less than four wheels with tire pressure sensors.
When installing winter tires or incorrect tire pressure sensors. (If this is the case, the yellow warning lamp in instrument cluster "system malfunction diagram" is set and cannot be deactivated by the system.)
The system has detected new sensors but the tire pressure monitoring button -E226- has not been pressed yet to confirm the current pressures. (In this case, the system malfunction is erased by pressing the button.)
TIRE PRESSURE MONITORING SYSTEM USAGE, DIRECT SYSTEM
Function
The tire pressure monitoring system is controlled by the Tire Pressure Monitoring Button -E226-, which is installed in the center console switch strip.
The system monitors the tire pressure you have set and entered for monitoring.
Tire pressures must first be checked, corrected and saved using the tire pressure monitoring button.
Then check and correct the tire pressure for the tires on the vehicle (including spare tire) according to the specifications on the sticker on the fuel filler flap/B-pillar.
Tire Pressure Monitoring Active
If the TPMS detects a loss of pressure in one or more tires, it notifies the driver by switching the TPMS warning lamp in the instrument cluster on continuously. A tire pressure warning symbol with the text "Check tire pressure" also appears in the instrument cluster driver information system. In this case, the tire pressures must be checked (according to the specifications on the label on the fuel tank door/B-pillar). If the tire pressure is very different in one or more tires, check that tire for damage or foreign objects. Replace the tire if necessary. Refer to TIRES, CHANGING, WITH TIRE PRESSURE MONITORING SYSTEM .
System Malfunction in Tire Pressure Monitoring System
A system malfunction is stored in the Tire Pressure Monitoring Control Module -J502-. If a malfunction occurs or there is already one present, this is indicated when the "ignition is on" by the yellow malfunction lamp in the instrument cluster blinking for 1 minute and then staying on continuously. The yellow malfunction lamp cannot be switched off by pressing the tire pressure monitoring button in the center console switch strip. A "tire pressure warning symbol" with the text "Check tire pressure" also appears in the instrument cluster driver information system. If there is a DTC memory entry, connect Vehicle diagnosis, testing and information system VAS 5051 A and select "Guided Fault Finding".
Coding Tire Pressure Monitoring Control Module
If Tire Pressure Monitoring Control Module -J502- is replaced, new control module must be coded. To do this, proceed as follows.
Connect VAS 5051 A perform vehicle-specific entry into Guided Fault Finding and select GO TO button "function/component selection".
Then
"Chassis (Repair group 01; 40 - 49)"
"Tire pressure monitoring (Repair group 01; 44)"
"01- On Board Diagnostic (OBD) capable systems"
"65 - Tire pressure monitoring J502"
"J502 - Tire Pressure Monitoring Control Module, functions"
"65 - Replacing control module (repair group 44)"
Tire pressure saving must be initiated after every desired change to the specified pressures.
Saving Tire Pressures
The correct saving of the specified values in the basic requirement for dependable tire pressure monitoring.
After each change to the tires, the tire pressure monitoring button in the center console must be pressed for approximately 5 seconds with ignition switched on and vehicle still until a signal tone is heard and the yellow "system malfunction diagram" in the instrument cluster blinks several times. Blinking several times confirms the calibration procedure and the readapting of the tire pressures.
The procedure for saving the tire pressures must be initiated each time the tire specified pressures are changed. The procedure takes place while driving.
Changing a Tire or Replacing a Tire Pressure Sensor
Adapting the tire pressure sensors is a basic requirement for the tire pressure monitoring system to function properly.
Each time a tire is changed or a tire pressure sensor is replaced, the tire pressure monitoring button in the center console must be pressed for approximately 5 seconds with the ignition switched on and vehicle still under a signal tone is heard and the yellow "system malfunction diagram" in the instrument cluster blinks several times.
If the tire pressure monitoring button is not pressed, the system learns the new sensors but still activates the malfunction lamp to request active operation.
The vehicle must now stand for 20 minutes and then be driven on a 3-minute adaptation drive at speeds greater than 25 km/h.
If the standing time is not followed, control module is not in learning mode so system recognizes a malfunction and can only automatically learn wheel electronics after standing 20 minutes.
Wheel alignment must only performed using VW/Audi-approved wheel alignment equipment!
Each time wheels are aligned, both front and rear wheels must be aligned.
Otherwise, proper vehicle drivability cannot be ensured.
Note. Wheels should not be aligned until the vehicle has been driven 1, 000 to 2, 000 km, since it takes this long for the coil springs to settle. The individual specifications should be followed as exactly as possible when making adjustments. Vehicle instability can also be caused by the wheels having a residual imbalance and/or radial runout which is too great.
| WARNING | After making adjustments on the suspension on vehicles with ESP or ABS, the steering angle sensor -G85- must be calibrated and steering must be readapted after vehicle alignment using the Vehicle diagnosis, testing and information system VAS 5051 A in Guided Functions. |
Then
