MAF wires
DO NOT touch or use anything that touches the sensor wires when you clean, or any other time...
They are very fragile and sensitive.
Good luck

Edit: I just noticed you have an A4 car. It is not wise to modify the MAF on an A4 car. The readings it sends the computer have a direct affect on line pressure in your tranny and several folks have damaged their trannys by modding the MAF. When you mod the MAF, I'm sure you know, it skews the readings sent to the computer which can help performance, but no one told the computer the readings are wrong for the electronic controlled tranny.
Good luck
