ATTENTION!! This app works only with VAG cars (Audi Volkswagen Seat Skoda Porsche) that are equipped with engines listed below; the full compatibility isn’t guaranteed for engines not listed, so if you buy the app, please consider that some or all functions may not work properly.
This app doesn’t work with other brand’s car due to a different diagnostic protocol.

VAG DPF shows you the most important information about the DPF particulate filter and its regeneration phases using an ELM327 Bluetooth/WIFI adapter. With this app you can know if the regeneration process is currently running, if a regeneration is waiting to be completed, how many km have you traveled since last regeneration, etc. This app doesn’t use standard OBD2 commands as most other apps, it uses CANBUS commands and this is the reason why it needs a decent ELM327 adapter to work (see the note below).

IMPORTANT!! Before to buy the full app, I suggest to try the app “VAG DPF Free” to check that your adapter, your Android device and your engine work properly with the app.

(*) = partial support or depending on SW version
(§) = only for 11-bit init protocol
IMPORTANT some of the engines above may be incompatible, it depends on the engine software version, so use the VAG DPF FREE app to check your engine before buy!!!!

Some words about ELM327 adapters:
– OBDLink LX: recommended, expensive but fast and reliable (I used it for the app development)
– Carista: recommended, affordable price but very reliable (I use it for debug and daily scans)
– Vgate iCar 2 Bluetooth : recommended, same as Carista
– Konnwei kw 903 : recommended, same as Carista
– China cloned adapter: not recommended, unreliable, you can randomly find decent adapters or fake adapters with unpredictable results

29-bit init protocol: Currently the app doesn’t support the 29-bit protocol engines, but it’s available the BETA engine group 97 that can be used for test, more details here:
