Maf cleaning

for those of you that think your maf may be shot give this a try first. ok after you remove the maf and vanes. aka maf vane removal. you can see the electrical sensor inside of the maf. on the side were the screens were hold the maf housing so you can see the silver electrical sensor. its very small. you'll need some isopropanol spray or the pen style(that what i used) take the pen and press it into the silver sensor to clean it. let dry for a day or two before putting it back in. you should notice a difference. BTW the pen style isopropanol is available at radioshack or do it best hardware stores. the main reason for a bad maf seems to be oil caused by the wierd pvc system and/or over oiled intake filters. after cleaning mine, the silver sensor looked a lot better than before. hope this helps someone

To add to what MeanAudiA6 wrote, the best method to spray the isopropanol is to angle the MAF so that the liquid drips off of the MAF away from the electrical harness... Be VERY gentle with the platinum wire in there (don't touch it!)... Also, I don't know if that last post implies that you must de-vane your MAF in order to clean it using this method -- de-vaning is something that you do to the MAF housing, not the sensor. Torx screws hold the Audi's MAF to its port, by carefully unbolting them, you can remove the MAF for cleaning. I have not tried it myself, but when I clean my MAF I will blow some compressed air in there (not too much) to help with the drying process. While giving it a day or two seems conservative but smart, I'd probably feel ok giving it an overnight dry after the compressed air.
