Hi,

I recently bought a used 2012 Mini Cooper with 40k miles.
The previous owner replaced the Mass Airflow Sensor (he did it himself), and did NOT reset the MAF adaptations.
I don't know how many miles the car had when the MAF was replaced.

I noticed that the car is not very reactive when I push on the gas pedal, and I was thinking that might be due to the old MAF adaptations.
There are no fault codes in memory.

Would you recommend resetting the MAF adaptations now?
Or is that going to be useless, since the MAF is not new?
