How to Reset BMW Check Engine Light via Autel MK808?

There is a check engine warning light on the 2016 BMW 3 series dashboard, so I’m gonna use Autel MaxiCOM MK808 Scan Tool to diagnose its reason and reset it.

I’ve got the MK808 plugged into the OBD2 port.

So let’s start, press

Diagnostics >> BMW >> Manual selection >> 3 series >> F30/F31/F35 >> Yes

Diagnostics >> Control unit >> Drive >> DDE(Engine-Diesel Electronics) >> Read codes


The Autel MK808 is giving 2 fault codes:

25F500 - Intake Air Temperature(IAT) sensor signal; circuit open/short to battery(+)

28D600 - HFM(Hot Film Air Mass Meter) signal; circuit open/short to ground or positive terminal.


If you don’t know what the codes meant, just put them into Google, it’ll exactly tell how to do it.


There is a fault with the mass airflow sensor. In fact, I’ve taken that out and put a new one in. But obviously, the BMW is still getting 2 fault codes and warning light.

So I’ll escape back to erase codes.

Erase code >> Yes >> OK


Codes have been successfully erased.

The check engine light has gone!

Done!
