Comments on KDIAG for Android

★★★★★ Сотир Сотиров · Dec 4, 2024

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

★★★★☆ Maryan Stoykov · Jan 24, 2026

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?

★★★★☆ Lateef Olayinka · Jul 13, 2025

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.

★★★★★ sarufa sukope · Dec 5, 2024

Very good and quick to connect unlike others. But need to upgrade more functions for Asian made vehicles. Nissan, Toyota , Mazda Isuzu and Ford Just to name a few.

★★★★★ Heulwen Van Wyk · Oct 31, 2025

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 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

Most functions do not work with KDIG scanner.

★☆☆☆☆ Sandor · May 8, 2025

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.

★☆☆☆☆ A Forrest · Nov 17, 2025

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.
