Audi A4 B9 8W active tire pressure monitoring air pressure in the MMI retrofit package

Upgrade your AUDI A4 B9 8W with the original tire pressure control HIGH.

This means your AUDI A4 displays the current tire pressure and tire temperature.

If there is a loss of pressure, you will receive a warning showing the affected wheel.

You can easily retrofit this safety system, which is only available for RS4 B9 models, in your AUDI A4 B9 8W!

After briefly plugging it into the very easily accessible OBD diagnostic interface in the driver's footwell, the KECODI coding interface supplied here uses the innovative KECODI that is already preset for you to completely automatically activate the active tire pressure monitoring system - NO further coding work with a tester is necessary.

Scope of delivery:

• - 1x original AUDI RS4 B9 8W control unit tire pressure monitoring
• - 4x original AUDI RS4 B9 8W tire pressure sensors (can be ordered optionally)
• - 4x original AUDI RS4 B9 8W valve caps + screw connections
• - 1x KECODI interface
• - 1x KECODI interface storage case
• - 1x pre-assembled cable set

Installation time: approx. 2 hours

Please select whether you would like to order the tire pressure sensors.

Please note the exclusion for vehicles from model year 2023 onwards with installed PR number NI8 (NI8 = Without UNECE CS (R155) and SU (R156) with SFD2-SG) or installed PR number NI7 (NI7 = With UNECE CS (R155) without SU (R156)).

Unfortunately, these models cannot be retrofitted or unlocked.

Please feel free to contact us to check before ordering.

Vehicles of the model year 2023 with installed PR number NI0 (NI0 = Without UNECE CS&SU) or vehicles of previous model years (e.g. 2022, 2021, etc., where this PR number does not yet exist) can still be retrofitted.

Product attributes:

The retrofitting of the original tire pressure control HIGH is possible on all AUDI A4 / S4 / RS4 B9 8W models of all years of manufacture (pre-facelift / facelift), all body styles (Avant, sedan, allroad) and all equipment variants.

The standard tire pressure system without pressure sensors (= PR number 7K1), which detects a loss of pressure (no exact air pressure / no temperature display can be shown) using the calculated value of the wheel rotation, is expanded to the HIGH system with display of the data of each tire.

This makes it very easy to inflate all tires evenly and check them in all driving situations.

The current tire valves are replaced with valves with tire pressure sensors; this standard installation is carried out by every tire service, for example.

The tire pressure sensors automatically report to the new tire pressure monitoring control unit while driving.

The display is shown on all models in the new menu item of your MMI multimedia system and on RS5 models also in the menu item "Sports display" in the Virtual Cockpit / Speedometer.

Tire pressure sensors:

Choose for yourself whether you would like to order the tire pressure sensors!

For example, if you already have a complete wheel set with tire pressure sensors already installed, you can continue to use them.

If you have not yet installed tire pressure sensors, you can also order 2 sets (= 8 tire pressure sensors) for your summer + winter tires.

Alternatively, it is also possible to install the tire pressure sensors only in the summer tires, for example. If you then install the wheel set without tire pressure sensors on your AUDI in the winter, you can simply switch the system back to the "normal" tire pressure system with the KECODI. The following summer, you can then simply switch the system back on with the KECODI.

We also offer the complete set of RDK sensors (= 4 pieces) separately under article number: 16510.
