Hi! 🚗 I'm looking for people with a VW / Audi / Škoda / SEAT / CUPRA to test my VAG Diagnostic app (Android). So far I've mostly tested it on a bench with a simulator, and now I need readings from real cars.

The test version only reads data: it detects control units, part numbers and fault codes. It does not clear faults, code anything, or change any car settings. The test takes about 10–15 minutes.

What you need:

• an Android phone,

• an ELM327 Bluetooth OBD adapter (e.g. Vlink); Wi-Fi adapters won't work,

• a VW group car, ideally from around 2012 onward (Golf 7, Octavia III, A3 8V, Leon III and newer). Older cars are useful too.

📥 Download the app:

The current version is tester-2 from 4 November. The app is available in English, German and Polish, and it automatically switches to your phone's language.

How to run the test:

1. The car is standing still, ignition on, and the adapter is in the OBD socket and paired with your phone.

2. In the app, tap the OBD connection card at the top, then "Connect" next to your adapter.

3. Choose "Full diagnosis." The first time, press "Activate PRO test" (it's free, you're not buying anything), then press "Full diagnosis" again.

4. Press "Run Auto-Scan VAG UDS," then "Run full Auto-Scan UDS," and wait until it finishes without locking your phone.

5. Press "Show result and fault clearing," take screenshots of the result, and go back with the arrow.

6. Press "Copy diagnostic log" and paste it to me in a private message or by email at [email protected]. Add the car, year, engine, gearbox and adapter.

🔒 The app masks the VIN and serial numbers in the log by itself. In the screenshots, cover the VIN if it's visible. Please send logs to me privately, not to the group.

⚠️ Don't use clearing in "Engine diagnostics" or "OBD Terminal," since Auto-Scan is enough for this test. Scan only with the car standing still.

If you have VCDS, OBDeleven or Carista, please also send a screenshot of their fault list. That comparison would help me a lot. A log from a failed scan is valuable too, so send it freely.

Thanks for your help! 🙏
