Obd Harry Customer Insights

1. Obd harry connected to my obd2 bluetooth and after full scan, no error found!! Really?!! The only correct info it gave me is engine temperature and the rpm! Which I don't need because I can see it on my car's dashboard!Phone overheats when after this app was opened (even after closing it).

2. It connected to my Bluetooth adapter without a struggle and read the code, but the free code wasn't much help, it was way too broad to pinpoint the issue.

3. The car is trickier, a citroen c3 pluriel that requires some other software to read and clear the codes that apparently only works with an old version of Windows, xp.

4. There are better alternatives out there than OBD Harry IMO.Showed everything about my vehicle including the trouble codes making the check engine light come on but it would not erase the codes when I attempted to do so.

5. So i figured I'd at least clear the Check Engine so i could use my remote start again, but that was wishful thinking too, since there was no way that i could find to do this, and no errors pointing to a faulty adapter.

6. Great!Read the code, but doesnt give you all the info without purchasing the full app.

7. IT'S JUST CLICK BAIT!Works great, needed to clear a engine light and see what caused it.

8. Finds an error code but then you must buy the full version to find out what the error is.

9. I did not try to reset the code, but suspect that this is locked out of the free version as well since they dont even give you any more than the trouble code.

10. The two other apps I tried prior to this one did not pick up my VIN number, even though a connection had been established for at least an hour or so.My car has a problem with ABS/ESP pump motor.

11. Not exactly easy to use, but not bad considering it is free.Connected immediately, easy to read and use.
