How to Reset BMW Check Engine Light via Foxwell NT680 Pro?

I’m going to show how to use Foxwell NT680 Pro Scanner to reset the check engine light for a BMW 3 series. As you can see, there is a warning light on the dashboard.

Diagnosis >> Control modules >> Drive >> Engine – DDE diesel electronics >> Read codes

It got 2 fault codes:
25F500 – Intake air temperature sensor, signal: open or short circuit to B+
28D600 – Hot film air mass meter, signal interruption, or short circuit to ground or positive terminal.

After working out there was a problem with the mass airflow sensor on BMW which I’ve now replaced actually. But the BMW still got a check engine light and the fault codes.

It is normal, what I need to do is go to “Clear Codes”.
Codes cleared!
Look, check engine light disappeared meanwhile.
Done!
