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. Supported engine codes include: CAAC, CAGA, CAHA, CAPA, CAYA, CAYB, CAYC, CCWA, CFCA, CFFB, CFGB, CFGC, CFHA, CFHC, CFHD, CFJB, CFWA, CGLB, CGLC, CJCA, CJCB, CJCD, CLAB, CLHA, CNHA, CNHC, CRKB, CRLB, CRMB, CRUA, CSHA, CUAA, CUDC, CUNA, CUPA, CUSA, CUSB, CUTA, CUUB, CUWA, CVUA, CVUB, CVUC, CXBA, CXEB, CXEC, CXFA, CXGA, CXGB, CXHA, CXHB, CXHC, CXXA, CXXB, CZZA, DAUA, DAVA, DBGC, DCBC, DCBE, DCXA, DDWA, DETA, DEUA, DEUC, DEWA, DEZE, DFBA, DFCA, DFEA, DFFA, DFGA, DFHA, DFLA, DFLB, DFSB, DFSD, DFSF, DFYA, DGDA, DGDB, DGTE, DGTC, DGTD, DHXA, DJGA, DLUB, DMMA, DMZA, DMZB, DNAA, DNAB, DNAC, DSRA, DSRB, DSSA, DSTB, DTNA, DTPA, DTPB, DTRA, DTRD, DTRB, DTRC, DTRE, DTSA, DTSB, DTUA, DTTA, and others. If your engine code isn't listed or sensors aren't detected, the app will let you know what works and offer to contact support. COMPATIBILITY NOTE: • Fully supported: VW Group diesel vehicles manufactured approximately 2012–2020 with EA288 or late EA189 engines. • Older vehicles (pre-2012): Some older diesel ECUs use legacy diagnostic protocols not accessible via standard BLE OBD-II adapters. Basic data (RPM, speed, coolant) may still work but DPF-specific sensors may not be available. • Newer vehicles (2020–2023): Some vehicles with SFD1 security gateways may restrict access to DPF-specific sensors. Standard OBD-II data remains accessible as required by law. • Newest vehicles (2024+): Vehicles with SFD2 security gateways block manufacturer-specific diagnostic data via standard OBD-II adapters. This is a manufacturer-imposed restriction affecting all unlicensed third-party tools. REQUIREMENTS: • Bluetooth Low Energy ELM327-compatible OBD-II dongle (e.g., Carista EVO, Carista Original, Vgate iCar Pro) • Diesel vehicle with DPF (Volkswagen, Audi, Skoda, SEAT) • iOS 16.0 or later The app includes a Simulation Mode for exploring all features without vehicle hardware. ## DPF Companion Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/78/77/80/78778049-734d-50bb-ddf0-1a801fcdeadb/appstore-screenshot-1.png/1284x2778.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/17/60/7f/17607feb-7353-6f6c-01f3-9caee761c0d6/appstore-screenshot-4.png/1284x2778.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/6a/ee/d8/6aeed8cc-5b9f-b5f5-3e04-3646ab55cc78/appstore-screenshot-5.png/1284x2778.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/a4/de/12/a4de12e6-f714-fd2f-a179-9e4b2e990696/appstore-screenshot-3.png/1284x2778.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/69/85/7c/69857caf-5e19-880c-96ca-c0da20b5e15d/appstore-screenshot-2.png/1284x2778.png) ## DPF Companion Rating Breakdown in United Kingdom - 5 stars: 3 (100%) - 4 stars: 0 (0%) - 3 stars: 0 (0%) - 2 stars: 0 (0%) - 1 stars: 0 (0%) ## DPF Companion Reviews in United Kingdom ### ***** "Look no further for DPF peace of mind !!" There’s not many apps that I use every day other than for music, but this app combined with its live data displays, wealth of statistics, GPS mapping, CarPlay and even an optional physical display is running on my dash every time. And if you’re not sure about something the product support is second to none !! -- Cnud99, 2026-10-18 ### ***** "Best DPF App Available" The Auto connect via Car play is a game changer! The app is the clearest, and easiest to use. With an option for a stand alone screen making monitoring DPF accurate and effortless. -- Kev.O T6.1, 2026-07-31 ### ***** "The BEST DPF monitoring app!" Without a doubt the best DPF monitoring app available for VAG vehicles. I’ve tried several over the years, but DPF Companion is on another level. The interface is incredibly clean, intuitive, and easy to understand, even if you’re not particularly technical. The standout feature for me is the countdown showing the estimated time until the next regeneration. It’s such a simple idea, but it makes planning journeys so much easier and takes all the guesswork out of DPF regens. The app is reliable, packed with useful information, and clearly designed by someone who understands what drivers actually need. HIGHLY RECOMMEND! -- Coose0687, 2026-07-25 [View all DPF Companion reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## DPF Companion Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Paid | United Kingdom | Utilities | #131 | ## DPF Companion Discovered Keywords - dpf companion ## DPF Companion Available In - [United Kingdom](https://apptail.io/app/dpf-companion-BzHA/united-kingdom) - [Belarus](https://apptail.io/app/dpf-companion-BzHA/belarus) - [Germany](https://apptail.io/app/dpf-companion-BzHA/germany) - [Finland](https://apptail.io/app/dpf-companion-BzHA/finland) - [Ireland](https://apptail.io/app/dpf-companion-BzHA/ireland) - [Norway](https://apptail.io/app/dpf-companion-BzHA/norway) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
