Tire pressure sensor Volkswagen Tiguan
Concern VW is famous for its thorough approach to ensuring a comfortable and safe driving of its cars. One of the important service devices used on Volkswagen is the tire pressure monitoring system.
From 2006 to 2013, the Volkswagen Tiguan was equipped with an indirect tire pressure monitoring system through ABS sensor readings. This version evaluated the distance traveled by each wheel in one complete revolution. When a difference in measurement was detected, a warning icon would light up on the dashboard, and the driver was required to check the pressure in all wheels (with a hand gauge, for example) to identify the damaged one.
Since 2013, Tiguans have had a tire pressure monitoring system with direct measurement (TPMS – “tire pressure monitoring system”). The system consists of the following elements:
- Special radio sensors with directional sensing in each wheel of the vehicle;
- A control unit with a receiving antenna, which reads in real time.
Reminder: car owners who prefer to have two sets of tires on their rims will need 8 wheel sensors and 8 special valves. When buying non-original parts, you must make sure that the frequency of the selected pressure sensors corresponds to the standard – 433 MHz.
TPMS principle of operation
When the car starts moving the wheel sensors start transmitting data to the control unit via a radio channel. Each sensor signal contains information about its identifier, pressure value and direction of wheel rotation. After a few minutes, the sensors are adapted, and the control unit by the level of the signal makes the linkage of their readings to a particular wheel of the front and rear axles. After this, the controller begins to display the current pressure readings on the screen of the Tiguan dashboard. The “Autolocation” function allows you to unambiguously determine in which wheel there was a decrease in pressure, and inform the driver about it.
The TPMS control unit and the receiving antenna are located on the outside of the car, in the area of the spare wheel. This ensures the most effective reception of radio signals from all wheel sensors.
The control unit is connected to the on-board power system of the car, and the tire pressure sensors have an autonomous battery with an estimated service life of 4 to 7 years. The manufacturer recommends replacing the Tire Pressure Sensors every 50,000 km.
Installing Tire Pressure Sensors
The pressure sensors are placed on the inside of the rim so that when the wheel is assembled the sensor is inside the tire cavity. The installation of the sensors can be performed by the car owner without much difficulty:
- A special screw with a square head is inserted into the sensor body, a valve is screwed on the mating part (but not tightened to the stop to allow for adjusting the height of the nipple on the wheel rim).
- Install the assembled assembly into the hole on the rim. The pressure sensor should be aligned to ensure the tightest fit to the rim and that the rubber o-ring on the valve is not skewed or jammed. Vertical adjustment of the nipple is also performed.
- The securing nut on the outer side of the rim is tightened, the pressure sensor is held in place by hand and the nut is screwed in until the o-ring on the valve nipple wraps around the rim of the housing on the inside of the rim.
Warning! According to Volkswagen Tiguan Owner’s Manual, tighten the valve nut with a torque of 8 Nm with a torque wrench.
All you need to know about tire pressure sensors Volkswagen Tiguan
When buying a car, users pay special attention to the comfort of its use. The comfort of the interior, the capacity of the trunk, as well as the stability of the car on the road is very important.
The car’s suspension and wheels have the greatest impact on the comfort of the trip. Such a small thing as a tire pressure sensor can save from unpleasant consequences, consider the functionality of the element, the original and analogues, which is better to buy, as well as such procedures as disabling and replacing sensors.
Features of the system
In the very first version, as well as in some restyled versions of the first Tiguan (until 2013) tire pressure controlled ABS sensor. The principle of operation was to measure the distance that the wheel travels during one of its rotation.
When there was a difference in these readings, the system sent a message to the on-board computer display, which recommended the driver to check the pressure in the wheels.
Since 2013, the German brand decided to use tire pressure sensors that work on the TPMS system in the Tiguan model. The system includes a control unit that analyzes and receives a radio signal directly from the sensors.
The pressure control system consists of several elements, below are its original components. It is worth bearing in mind that some elements should be purchased in double quantity if you use two seasonal sets of wheels.
|Item||Code||Approximate price (rubles)|
|Control unit||3AA 907 273 (B, D or F)||9000|
|Control unit mount||5N0 907 538||200|
|Connector for block connection to wiring||8E0 971 934 A||400|
|Nipple (metal)||4D0 601 361||500|
|Wheel sensor||5Q0 907 275 B||3000|
Since the elements are not very complex, it is quite possible to buy non-original elements of the system. It is better to pay attention to the parts that are produced by proven brands. The main thing you should pay attention to is the compliance of the analog to the required parameters, the main criterion is the frequency of the sensor, it must be 433 MHz .
If the original parts, as a rule, automatically synchronized with the onboard computer, with some analogues can be difficult. VCDS software will be required to register third-party sensors.
Disabling and resetting
Some owners want to turn off the pressure monitoring system, there can be many reasons for this, most often such a need arises in the case of the purchase of a second set of wheels without sensors.
Some instances of Tiguan can adapt to the operation of the new wheels on their own, and some will continue to attempt to obtain pressure data and, accordingly, generate an error on the screen of the onboard computer.
This option can be deactivated by connecting a computer via the diagnostic connector. In some configurations it is possible to disable the option directly from the on-board computer, as a rule, the option is controlled in the “Comfort” menu.
If the sensor behaves incorrectly, you may need to reset it, to perform the operation, you can use one of the ways:
- deflate the wheels and inflate them again;
- drive for 15 minutes at 80 kilometers per hour;
- use the reset button;
- Disconnect the battery for a while.
The sensor is located on the inside of the disc. The installation process itself is not particularly difficult and can be performed independently.
