AirGuard – Fit for tyre pressure monitoring systems!

The all-in-one unit for TPMS

We offer a complete range of tyre pressure monitoring systems (TPMS). Our AirGuard is a programming/diagnostic unit for tyre pressure monitoring systems and makes it possible to perform work directly on the vehicle without an Internet connection. In line with this, we also offer the Herth+Buss tyre pressure sensor, which can be used in all vehicles with an active TPMS installed as standard. Our AirGuard can read out all tyre pressure sensors on the market and then copy the data read out to the Herth+Buss TPMS sensors automatically or manually. As we are constantly developing our products, our range features the AirGuard 3.0 and 4.0
according to the individual budget and technical requirements. Below, we now explain the differences between the two tyre pressure monitoring systems.

AirGuard 4.0

With our AirGuard 4.0 tyre pressure monitoring system, the OBD II teaching-in functions that were otherwise only available via the AirGuard 3.0 adapter are already incorporated in the device. In addition, the AirGuard 4.0 can be charged using an USB port, i.e. also using a vehicle's cigarette lighter. Further benefits of our AirGuard 4.0 tyre pressure monitoring system:

OBD II Bluetooth module

With our additionally available OBD II Bluetooth module, you can now connect the AirGuard 4.0 via Bluetooth for the first time. Please note that the OBD II Bluetooth module is designed only for use with the AirGuard 4.0 tyre pressure monitoring system.
The OBD II Bluetooth module lets you read out and delete fault memories (DTCs).

OBD II Bluetooth module – Questions and answers

What are the functions of the OBD II Bluetooth module?

First of all, it is important to know that the OBD II Bluetooth module can only be used in conjunction with our AirGuard 4.0. It is an optional extra to the AirGuard 4.0 and must be ordered separately. The OBD II Bluetooth module and the AirGuard 4.0 can now be used to read out and delete fault memories for the first time.

How do I use the OBD II Bluetooth module?

The OBD II Bluetooth module can be connected to the AirGuard 4.0 using Bluetooth. It is an optional extra here.

How is the adapter data updated?

Updating is performed by downloading the update, as for our AirGuard TPMS programming/diagnostic unit. See below. Special feature: Software can be updated via WiFi® or a cable.

What do updates cost?

The updates are free of charge. See below.

Questions and answers on tyre pressure monitoring systems

TPMS - Legal requirements and market potential

Specifications as per EU regulation ECE-R 64
All vehicles in model classes M1 and N1 registered for the first time since 1 November 2014 must be equipped as standard with a tyre pressure monitoring system (TPMS). This relates specifically to passenger cars, mobile homes and commercial vehicles with a total weight of less than 3.5 t and licensed to carry up to eight occupants. Road safety is one of the reasons behind the new regulation – Tyre leaks are detected quickly and automatically by the tyre pressure sensor. Another reason is that correctly inflated tyres reduce fuel consumption and with it CO2 emissions. Since May 2018 defective tyre pressure monitoring systems have been a serious problem for the TÜV inspection agency and mean re-inspection is required. This legal position applies to all vehicles that must be equipped with a TPMS in accordance with the legislation.

What are the minimum requirements to be observed?

ECE-R 64 stipulates the following minimum requirements for tyre pressure monitoring systems:
A warning must be given with a pressure loss of 20 percent or more or with a tyre pressure less than 1.5 bar.

A defective tyre must be detected within ten minutes.
If all four tyres are affected, the time must not exceed 60 minutes.
A defective system component must be indicated within ten minutes.
The tyre pressure monitoring system must function with an average speed of 40 km/h or more.

What are the consequences for workshops?

The replacement of TPMS sensors is a source of additional business and greater customer loyalty for independent workshops and tyre services. The number of new cars with tyre pressure monitoring systems will increase dramatically and with it the demand for winter tyres for vehicles, which then have to be retrofitted with TPMS sensors. Workshops and tyre services should therefore adjust to this new situation.

Which system do vehicle manufacturers tend to opt for?

Vehicle manufacturers tend to opt for the active measuring tyre pressure monitoring systems using radio sensors. This is faster and more precise than the passive measuring system using ABS/ESP.

Which languages are programmed on the AirGuard?

German, English, French, Spanish, Dutch, Italian, Finnish (Suomen Kieli) and Slovenian are currently available. If there is a demand for other languages to be added, they will be provided via an update on the website.

Can TPMS sensors from other manufacturers also be adapted with the AirGuard?

The AirGuard concept is a self-contained system. Third-party / OE sensors can only be read out or copied. Programming of third-party tyre pressure sensors is not possible.

What happens if the desired vehicle model cannot be displayed?

If the vehicle model is not present, reference can be made to an older model. Please always see herthundbuss.com/AirGuard#update to check you have installed the latest update. However, it is also possible that the model is installed with an indirect measuring tyre pressure monitoring system (e.g. SEAT).

Herth+Buss tyre pressure sensor

To programme our tyre pressure sensors and align them with the relevant vehicle, you will need one of our AirGuard devices. Special features of our TPMS sensors:

Programming and alignment within five to fifteen seconds per tyre pressure sensor
The original ID number can be copied to the new one from the old TPMS sensor or re-allocated
Tyre pressure sensor can be rewritten
Sensors can be ordered individually and come with a complete valve

TPMS sensors – Questions and answers

Is the Herth+Buss tyre pressure sensor available as a retrofit solution for vehicles without TPMS?

No. Herth+Buss tyre pressure sensors should only be used for vehicles fitted with TPMS by the manufacturer.

How long is the service life of a battery installed in the TPMS sensor? Can the battery be replaced?

The service life of the batteries in the tyre pressure sensor is three to seven years. The battery is permanently encapsulated in the sensor and cannot therefore be replaced.

Can the vehicle data in the TPMS sensor be deleted?

No. The data can be overwritten any number of times.

Can the tyre pressure sensor be adapted to any rim?

Yes, the sensor angle can be adjusted as required.
