Project Background
The second generation of BMW MINI Cooper S is a great car, but it is missing important metrology from the factory. It has a coolant temperature sensor, but there is no gauge to view the temperature. Technically a driver can view the temperature by entering a secret menu, but this is not practical except for debugging purposes as it requires a long series of inputs to display. The car otherwise uses the coolant temperature sensor only to flash a warning light when the engine has already overheated.Knowledge of engine temperature is important to me for two reasons:
- Situational awareness to know when engine is up to temperature in order to use full throttle and rev range
- Situational awareness in case of cooling system failures, such as leaking plastic thermostat housing
Aftermarket solutions such as the ScanGauge II and CravenSpeed Gauge Kit exist; however I felt that the ScanGauge did not suit the interior design style of the MINI, and the CravenSpeed kit cost cost more than I was willing to spend on an accessory. This project aimed to add an engine temperature display to the MINI that fits the MINI's interior design language and to take advantage of other sensors that the vehicle has to offer.

Where can I download the DCAN Distribution Board v1.1 KiCad files?
From the abeednaz/R56-Mini-MFD repository on GitHub, at the commit this page was made from: the board is PCBs/PCB_v2/DCAN_Distribution_Board_v1.1/DCAN_Distribution_Board_v1.1.kicad_pcb and its schematic PCBs/OBD port power distribution board/V2.7-Connector-board/V2.7-Connector-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DCAN Distribution Board v1.1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask abeednaz before reusing the design.
