I wonder what OBDII adapters and what Apps are you using? For what purposes? 

I'm interested in Android apps, but perhaps iOS versions can be interesting too, for other friends with Apple phones.

I have got OBDLink LX adapter and have tried Torque app. I'm not excited. Maybe some custom PIDs is needed. 

In my another topic Russ77 mentioned "VAG DPF"

Free limited version.

Paid

Looks interesting, didn't try for myself, just installed free version for tests.

 

I carry both my ELM327 and OBDEleven dongles around with Torque Pro and OBDEleven on my Android phone, however I also have VCDS on a laptop at home, should I need it.

I used Carista. £15 on Amazon. And have been able to do everything want with it. You have to paid to unlock extra features, which I did as and when I needed them.
