Air Flow Meter S5 question
 

Hey everyone! I was just wondering what the model number is for an air flow meter for a S5 13BT?

I'm seen both the:

N370 197200-0020
N370 197200-0021

and was wondering which model number would be the one for my car?

thanks!

either will work, we only care about the N370 part

Thanks! I appreciate it!

Just out of curiosity, do you know the difference between the models?

could be fed/cali emissions.

there was a bulletin/service campaign for the S5 AFM's, and so there was a revision, and the revision had a white dot on it
