DPF Companion

Store description excerpt

DPF Companion is a real-time diesel particulate filter monitoring app for diesel vehicle owners. Connect to your vehicle via a Bluetooth OBD-II dongle and get instant visibility into your DPF health, regeneration status, and engine performance. KEY FEATURES: • Live DPF Monitoring — Track soot loading in real-time with a visual gauge showing percentage and grams. Know exactly when your next regeneration will occur. • Regen Countdown Timer — Estimates minutes remaining until your next DPF regeneration starts, or until an active regen completes. Never be caught mid-regen on a short trip again. • Smart Vehicle Alerts — Notifications when a regen is approaching, when one is predicted based on your driving pattern, when fuel efficiency drops, and when your device needs syncing. • Trip Recording — Automatic trip detection with GPS routes, fuel consumption, driving style analysis, and distance tracking. Works with phone connected or standalone device. • Multi-Vehicle Support — Automatically detects and tracks multiple vehicles. Each vehicle maintains its own trip history, regen data, and health scores. • DPF Health Dashboard — Overall health score based on regeneration patterns, soot trends, and driving habits. • Fault Code Scanning — Read diagnostic trouble codes from all vehicle ECUs. Read-only — never writes to your vehicle. • Fleet Insights — Compare your vehicle's DPF performance against other vehicles. • CarPlay — View DPF status, soot levels, and regen countdown directly on your car's built-in display. • Companion Device — Optional ESP32 hardware device that mounts in-vehicle for a dedicated always-on DPF display with buzzer alerts. Buy the hardware directly from Waveshare for ~€25 and flash it yourself using our free web flasher. • Pay What Is Fair — Voluntary support option. The app is fully functional regardless. If it helps you, consider supporting continued development. SUPPORTED VEHICLES: DPF Companion works with Volkswagen Group (VW, Audi, Skoda, SEAT) diesel vehicles equipped with a DPF.
