about intake valve cleaning.

[fkompass]

Hello,

is there anyone here who has done cleaning the throttle body and intake valve before?

I have already bought "CRC intake cleaner" from REPCO.

They told me that it must be sprayed to avoid a MAF (mass air flow) sensor.

But I couldn't find that sensor.

MY car is 2012 polo 1.2 77tsi model.

please let me know where is MAF sensor located.

thanks.
