I need to replace the PCV valve (breather valve, vent valve) on my 2003 A6 3.0L engine. I believe the original part is 06C-103-245. I can buy it online for about $110. I also found part 077-103-245 which looks the same in pictures, though I don't know anything about its dimensions. This part is available for $50. Does any one know if 077-103-245 can replace 06C-103-245?
Thanks

 

Never Mind. I found good pictures of both parts, and they are not interchangeable. 077-103-245 connects to hoses. 06C-103-245 connects to an orifice with o-rings.
