Canbus and problems using an bluetooth OBD2 scanner.

I would like to connect my DUDU7 to the canbus of my car, but not sure wich one to choose from the list. Can anyone help me with this? Its an 2010 Subaru Impreza Hatchback, 2.0l Diesel, with original navigation. Currently Im using an bluetooth OBD2 scanner, but this one is causing problems. After a few minutes of driving the warning lights in my dashboard starts flashing, and i have to use CarScanner to delete fault codes. This is only a problem when I connect with the DuduOS. CarScanner and Torque does not have this problem. I'm using the DUDU OS 3.5.

This is the sticker on the ECU.

This is the OBD2 Scanner.

The issue with the OBD2 scanner only happens when Im using DUDU OS to connect. If I use Torque, or CarScanner, there are no issues whatsoever.

I can also mention that I think the head unit is connected to the canbus, because when I put the car in reverse, it does detect the reverse, and changes screen. The reverse camera are only connected to the head unit, not to the reverse light.

Small update. After taking pics of the scanner, I plugged it in and took the car for a drive, and now it worked. No problems with flashing warning lights.

But one question I have is, what info can I expect to get from the scanner? The original HU would show both instant and average fuel consumption. All Im getting from DUDU are battery woltage and coolant temperature. It does not show outside and inside temperature.

Teklock Just the head unit and cables for connecting to the canbus, wich should be enough i guess. Just not sure if my car is supported.
