Question about 2004 Audi A4
I tried replacing it but i cant figure out how to open up the filter box with out breaking some thing . If you can help it would be great
You must undo all hoses and unscrew the two screws. if you mess up the air sensor will be broken and some of the hoses have to be replaced. it will cost in excess of $400 in parts alone where as Audi dealer will charge $130 to change the filter for you. I had to pay $750 to fix the damage I caused.

replacing your air filter I guess is your question. best way I have found is quite simple. 1.8l disconnect the N80 valve on way valve solenoid normally in a rubber housing connected to your intake air duct. remove small clamp and connector. remove intake air duct two phillips head screws on core support. remove two top screws from top of air box. you may have to loosen up the wiring that is held in place by clips to make it easier. spread box open pull out air filter... CURSE ALOT. then do the exact opposite for reassembly.
