Doesn’t always connect successfully first time via Bluetooth so a little annoying but overall very happy! ### 5/5 — Highly recommended *2026-06-16* Great app for viewing DPF status, the car play app is also great to monitor and allow the car to fully regen before turning it off ### 4/5 — Funktioniert jetzt *2026-05-10* Carly Universal Adapter ist verbunden und die richtige Gruppe ausgewählt aber in der App werden keine Werte angezeigt. Völlig nutzlos und Geldverschwendung Edit: Manchmal muss man den Adapter abziehen und wieder neu anschließen. Danach funktioniert es. Wenn es läuft wird alles super angezeigt **Developer response:** Reach out for help at support@dpfmonitor.com - there's nothing I can do to help you via a review. ### 5/5 — arteon 2.0 tdi *2026-02-26* very good ### 1/5 — Not good *2026-01-16* Won’t connect ! **Developer response:** Reach out at support@dpfmonitor.com for support - there's nothing I can do over a review to help you. ### 5/5 — Ottimo *2026-01-10, version 2.0.1* Ho risolto tutti i problemi di mancata rigenerazione !!! ### 2/5 — Nefunkční s obd327 wifi *2026-01-10, version 2.0.1* Platíte peníze za něco co stejně nefunguje, ikdyž psali že již podporuje připojení WiFi. ### 2/5 — Non funziona *2026-01-09, version 2.0.1* Salve ho un Fiat 500x e ho comprato un obd2 per monitorare il dpf ma non si collega come posso fare ? ### 5/5 — App *2026-01-05, version 2.0.1* Ho un Alfa Stelvio q4 210cv del 2020 e non riesco a connettermi, sarà che non so che gruppo faccia parte il mio motore???
