Know exactly when your DPF regenerates — not after the fact.
A background alert app for BMW F/G-series diesel owners. Connects to your existing OBD-II Bluetooth dongle and reads your DME/DDE's own DPF status directly — no guessing, no invented thresholds.
Buy BIM DPF GUARDReal-time soot mass
Live soot mass reading and a color gauge showing how close you are to a regeneration, right on the home screen.
Start & finish alerts
A notification (with sound) the moment regeneration actually starts, and another the moment it finishes — so you know when it's safe to end your trip.
Runs in the background
No need to keep the app open. It reconnects to your dongle automatically and keeps watching, even if your phone is in your pocket.
Works with your existing dongle
Uses a standard ELM327-compatible Bluetooth OBD-II adapter (e.g. Carista) — no proprietary hardware to buy.
Which cars does it support?
BIM DPF GUARD reads data directly from your car's own diesel engine control unit (DDE), the same way tools like bimmer-tool or Carista do — not invented or estimated. Confirmed on BMW F/G-series models with the B47 (4-cyl) and B47D engine family, with promising early signs for the older N47 generation as well. Coverage is expanding as more real cars get tested.
