Seem to be getting really poor fuel efficiency with my A3 1.8 SE 8L. Think it might be time to change the MAF sensor.
Looking on GSF's website they have one for £28 (187VG0010 AGN), one for £102 (187VG0011 AGN)and one for £111 (187VG0030 APG). They all look the same to me. Can anyone tell me the reason for the price differences and which one I should be getting?
The ones at £102 and £111 also offer £30 cashback if returning the old part. Also anyone know what the AGN and APG means?
Any help is much appreciated. Thanks in advance.
