ATTENTION!! This app works only with VAG cars (Audi Volkswagen Seat Skoda) that are equipped with engines listed below; for diesel engines not listed is not guaranteed the full compatibility so if you anyway buy the app consider that some or all functions couldn't work correctly.
This app doesn't work with other brand's car due to a different diagnostic protocol.

VAG DPF shows you the most important data related to the DPF particulate filter and its regeneration phases using an ELM327 Bluetooth/WIFI adapter. With this app you can know if the filter is actually in regeneration process if a regeneration is waiting to complete how many km have you traveled since last regeneration etc. This app doesn't use standard OBD2 commands as almost all other apps it uses directly CAN commands specific of car model and this is the reason why it doesn't work with every car; due to the use of CAN commands the app needs al least a decent ELM327 adapter (see note below); some users reports correct app working with a 10-15 euro adapter.

IMPORTANT!! I suggest to try the app "VAG DPF Free" to check the correct functionality of your adapter and your Android before to buy the full app.

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!!!!

Core functions:
- Display of 12 DPF filter parameters like: soot mass accumulation in the filter regeneration duration km traveled and time passed since last regeneration EGR valve closing exhaust gas temperatures of inlet and outlet of DPF (Attention: data shown may vary depending of the engine type due to the presence of the parameters into the engine ecu)
- Manual or automatic parameters update
- Display for all the parameters of the previous value and the difference between the actual and the previous value (only for automatic update delays different from 0 seconds)
- Ability to exclude one or more parameter to increase the reading speed
- Display of the filter filling percentage before reaching of the filling limit that starts the execution of a field regeneration (standard regeneration controlled by the engine ecu)
- Graphical display using a progress bar of the filling percentage value before starting a field or a service regeneration
- Graphical display of the filter status: red filter for the regeneration phase (passive field or service) of grey filter with different back internal areas depending on the filling percentage value
- Display of extra data: adapter communication error counter filter filling rating in µg/min update time of all the 12 parameters automatic update delay actually selected in options menu
- Notification bar icon to show an active connection and the auto-update process running

Some words about ELM327 adapters:
- OBDLink LX: recommended expensive but fast and reliable (I used it for development of this app)
- Carista: recommended affordable price but very reliable (I use it for debug and daily scans)
- China cloned adapter: not recommended unreliable you can randomly find decent adapters or fake adapters with unpredictable results
