Audi A4 B9 Display - Unleash the power of data

Introducing our advanced display for the Audi A4 B9 (including S4/RS4) and A5 F5 (including S5/RS5) models. This state-of-the-art display gives you access to all the data from your engine control unit—and we mean all. Our display interrogates the sensors directly via the CAN bus protocol and displays the information on our reliable MFD28 display. The Audi A4 B9 display blends seamlessly into your vehicle's interior design thanks to a custom-made frame that mimics an original part.

We have optimized the manufacturer-specific Can Bus protocol to achieve maximum query speed.

Important features:

Perfect integration into the vehicle interior
Query up to 128 sensors
10 individually customizable views with our DSS - Display Setup Software
Preconfigured views for a quick start with our display
Easy plug-and-play installation with our cable kit – just plug and play
4 additional analog inputs for monitoring exhaust gas temperature, oil pressure and more
Direct integration of the ethanol sensor
Best readability with optional anti-reflective film
Sensor query at the same level as manufacturer tools

Additional features:

Performance Meter : Measure your acceleration times with our Performance Widget – 0-100, 100-200, 0-200.

Data recording: Record all data to the internal SD card – whether "on demand" (start with a fingertip) or permanently. All data from your last ride is saved.

Preset Alarms: Enable and customize predefined alerts, such as a significant warning when the exhaust temperature exceeds 900 degrees.

4 additional analog inputs: Connect additional temperature and/or pressure sensors for further monitoring options, such as exhaust gas temperature or exhaust back pressure. An ethanol sensor can be connected to one of the digital inputs.

Error reading/error deletion: Read errors from the engine control unit in plain text and delete them.

Customization: Customize the home screen or choose from various widgets to design the display according to your wishes.

Seamless vehicle integration: Our display fits all left-hand drive Audi A4 B9 and A5 F5 vehicles. A right-hand drive version is currently in development.

Access all engine control unit data: We supply your display with a preconfigured TRI file as standard. This file defines all sensors that can be queried, including:

Temperatures: engine coolant temperature, intake air temperature, exhaust gas temperature, transmission temperature.

Pressures: boost pressure, ambient pressure, oil pressure.

Lambda/Mixture: Lambda target/current, short-term lambda adjustment, long-term lambda adjustment, MAF, engine load, torque.

Driver dynamics: brake pressure, vehicle speed, throttle angle/accelerator pedal position.

Other: speed, total ignition angle, gear, battery voltage, ignition angle correction per cylinder.

Analog Inputs: Additional sensors such as oil temperature, fuel pressure, oil pressure, exhaust gas temperature and more can be added, including an ethanol sensor for flex-fuel vehicles.

Please note that not every engine provides all of these values.

For which engines and models is this Audi A4/A5 display suitable?

The display frame fits all left-hand drive (LHD) Audi A4 B9 and A5 F5 vehicles. A right-hand drive (RHD) version is currently under development.

Scope of delivery

Included in delivery:

MFA28 Gen2 data display integrated in the cluster
Quickstart Guide
USB data cable
SD card (pre-installed in the display)
SD card adapter
Display film (to avoid reflections)
Plug-and-play connection cable to the OBD port

Connection and expansion

All sensors can be connected via the four analog inputs – we support linear 0-5V and NTC sensors.
Our proprietary CANchecked display sensors are stored in the TRI/TRX files by default and simply need to be connected:

AIN1: Temperature sensor
AIN2: Converter for exhaust gas temperature sensor type K
AIN3: Pressure sensor 0-10 bar
AIN4: Boost pressure sensor 0-5.5 bar absolute

In addition to the analog sensors, you can also connect our external shift light with 8 LEDs. This can flash in different colors, and the speed limits and colors can be configured directly on the display.

Connect the ethanol sensor directly to the display. You need a pull-up resistor (10K) between 5V and the signal. Then you can display and log the ethanol content and temperature directly on the display.

Advanced features

Math channels allow you to combine sensors into calculations. The user table allows you to generate additional sensors with 2D or 3D maps.

Installation instructions:

We provide an illustrated installation guide to make the installation process hassle-free.

Unleash the full potential of your Audi A4 B9 or A5 F5 with our advanced display. If you have any questions or need more information, please don't hesitate to contact us.
