CANchecked MFD28 Gen2 for VW Caddy MK4
The MFD28 Gen2 replaces the air vent with an integrated data display while still allowing airflow. Designed for straightforward installation; illustrated instructions are available for most displays, making self-installation possible without a workshop.
Key features
- Vehicle-specific integration: Bezel designed to fit the vent and keep airflow past the display
- CAN bus readout: In-depth vehicle data similar to manufacturer diagnostic tools
- Gear display: Via CAN bus or calculated from speed and RPM
- Touchscreen operation: Page navigation with swipe gestures
- Custom pages: Create your own layouts, add pictures, or use a start animation
- Extra inputs: Up to 4 analog inputs plus direct ethanol sensor support
- CAN switching: Use the display as a keypad and send custom CAN messages
- Configurable alarms: Custom warning thresholds (example: EGT warning above 900 °C)
- Data logging: Save logs to the internal SD card for later analysis
- Performance meter: Measure 0–100, 100–200, and 0–200 times without additional hardware
- DTC*: Read and clear faults for engine ECU, transmission, ABS, and all-wheel drive
- Dimming*: Automatic dimming with the instrument panel
Views and page layout
- Delivered with predefined sample pages
- Create your own pages (up to 10 pages)
- 20 widget types (e.g. sensor value, analogue pointer, YT diagram, speed bar, round display, vertical/horizontal bar)
- Drag-and-drop positioning and scalable widget sizing
- Fully adjustable widget colours
- Up to 64 widgets per page
Display Setup Software (DSS)
DSS is used to customize the display, download and view log files, and use the integrated CAN logger. The built-in TRI Editor lets you configure sensors (CAN bus or internal), set min/max values for warnings, and rename sensors.
Supported data and protocols
CAN bus data queries are supported (UDS, TP2, manufacturer-specific protocols) as well as K-Line (ISO 9141). The display is supplied with predefined TRI/TRX files; available sensors vary by engine. Examples include:
Temperatures
- Exhaust temperature, coolant temperature, oil temperature, intake temperature, outside temperature, gasoline temperature, DSG temperature
Pressures
- Boost pressure, ambient pressure, fuel pressure pre-feed pump, rail pressure (actual/target)
Lambda / mixture
- Lambda value, injection time, short-term lambda adjustment, long-term lambda adjustment
Other
- RPM, air mass, vehicle speed, throttle angle, total ignition angle, ignition angle retraction per cylinder, N75 timing (%), terminal 30 voltage, torque, gear, diesel-specific values
If values are missing, they can be added later.
Scope of delivery
- MFD28 Gen2 data display integrated in the ventilation insert for RHD vehicles
- Vehicle-specific connection cable
- Quickstart guide
- USB data cable
- SD card (pre-installed in the display)
- SD card adapter
- Display foil (to reduce reflections)
Connection and expansion
Four analog inputs support linear 0–5 V and NTC sensors. CANchecked in-house sensors are stored in the TRI/TRX files by default and only need to be connected:
- AIN1: Temperature sensor (NTC01)
- AIN2: Type K EGT converter (TCC01)
- AIN3: Pressure sensor 0–10 bar (FLP01)
- AIN4: Boost pressure sensor 0–5.5 bar absolute (BST01)
A pre-assembled AIN wiring harness can be used for connection.
An external shift light with eight LEDs can also be connected, with configurable colours and speed limits directly on the display.
An ethanol sensor connects directly to the display. A 10 kΩ pull-up resistor is required between 5 V and the signal line to view and log ethanol content and temperature on the display.
Advanced functions
- Math-Channels: Calculate channels using other sensors
- User-Table: Create additional sensors using 2D or 3D maps
Optional accessories
- CC24000 SLM08 - external switching lightning module
- CC22780 ANC04 - four-way AIN-harness
- CC22100 CBD08 - eight-way CAN Distribution Hub
- CC22902 NTC01 - temperature sensor for liquids 1/8 inch NPT
- CC22903 TCC01 - type K converter 0–1250 °C
- CC22901 FLP01 - pressure sensor 0–10 bar (145 psi) M10x1
- CC22900 BST01 - pressure sensor 0–5.5 bar absolute (80 psi)
* Not available on all protocols.
