There is a check engine light showing on the dashboard of a 2020 BMW Mini Countryman. So I’m gonna use Autel MaxiCOM MK808 OBD2 Scanner to reset it. It also works on a lot of other makes, models, and years. For more advanced functions, you may choose Autel MK808TS, MK808BT as well.
Diagnostics >> EOBD >> Autoscan >> OK >> DTC & FFD >> Read codes
Autel MK808 tells a fault code:
P0103: Mass or volume air flow sensor “A” circuit high.
In fact, I’ve already changed the mass airflow sensor, but the Mini is still getting a warning light. So I need to use MK808 to clear codes.
Clear DTC >> Yes
No-fault codes detected.
Let’s start the engine, if the check engine light goes off then it’s done.
Yeah, it’s actually gone off.
Sometimes if it doesn’t work, you can select a specific vehicle instead of EOBD.
In addition, it’s worth mentioning that purchasing the Original Autel Diagnostic Tool on www.obd2shop.co.uk can protect your vehicle from damage by a fake or cloned tool.
