Description
DPF Companion gives you real-time visibility into your diesel particulate filter — so you always know when a regen is coming, when it's happening, and when it's done.
Connect to your vehicle via a Bluetooth OBD-II dongle (Carista EVO recommended) and see live data on a circular dashboard designed for quick glances while driving.
What you can monitor: Soot loading percentage and actual grams Regen status with audio alerts when a regen starts, progresses, and completes Estimated time remaining until the next regen or until a current regen finishes DPF inlet and outlet exhaust temperatures Oil temperature, coolant temperature, and engine RPM Current speed with colour-coded gradient Fuel consumption (L/100km or MPG) Distance and time since last regen Ash residue and odometer
Key features: Two dashboard screens — DPF monitoring and Speed/RPM — swipe between them or view both side by side in landscape Regen history log with duration, soot burned, and average burn rate Auto-discovery detects which sensors your vehicle supports on first connection Customisable display — toggle inner and outer metric groups on or off Tap any element on the dashboard for an explanation tooltip KM or Miles preference Simulation mode for exploring the app without a vehicle connection Optional DPF Companion device support (ESP32-S3 dedicated in-vehicle display)
Supported vehicles: Currently optimised for VAG diesel vehicles (Volkswagen, Audi, Skoda, SEAT) with DPF systems from 2008 onwards. Other vehicles may work with limited functionality.
Requirements: A Bluetooth ELM327-compatible OBD-II dongle (we recommend the Carista EVO) The dongle must be plugged into your vehicle's OBD-II port Phone should be kept on charge while using the app (screen stays on with active Bluetooth)
