Very good app but please add the Alfa Romeo because I see there is Bugatti but no alfa?

KONNWEI has three apps for their BT scan tool! KDIG and MAXOBD2 require the BT dongle to be plugged into the vehicle's OBD2 port. Both apps require permissions to be set manually within the app settings menu to work. KDIG app instructions say user should not connect BT dongle to phone BT and should use function to connect BT within the app!

I think some softwares need to be updated. I can't scan Transmission system of Toyota cars. Transmission function is not there at all. Try to work on Peugeot vehicles too.

App works perfect! I have problem with the Opel brand with professional diagnostic. I can't connect to Opel Astra J.

The Bluetooth device is great but the app lacks the ability to log data and export it to a .csv file for example. It works great with Car Scanner but Car Scanner does not read all PIDs at least on a 2011 Hyundai I30 1.6 CRDI. Can a logging option be added?

I bought this device and still can't connect via Bluetooth and the app.I called the konnwei dealer and can't resolve the issue. For me its jst useless and I don't encourage anyone to buy it. Konnwei 903 wireless 5 Bluetooth

I've bought it for my InfinitiFX35 2007, but unfortunately, it's too poor for Nissan x Infinite cars. It doesn't even have Autosearch by VIN number for it. It is great with Kia bad with Japanese cars, I guess, because I've tried to use with Mitsubishi, and it won't even read the VIN. It keeps saying that it is out of value, for Korea car it good for Japanese is not the one to GO with.

Why is the location needed to use the app? This should not be a requirement. As the location does not help with the software on the app. e.g. there are functions there that don't work or not recognized so on. Would be great to have access to these functions.

Glad I didn't buy the obd2 connector! The KDIG OBD2 on AliExpress had pictures of it having holden protocols, it doesn't even have holden in it.

Had a lot of hope for KDIG, but it can read neither of my cars. It only shows basic info like every cheap obd does. Unfortunately KDIG OBD is useless, same as the app.
