I have a 03 3.0 quattro that chucks the post cat o2 sensor code like crazy. A friend of mine recently got a spacer from black forest ind. to fix the same prob on his 02 golf. says it hasn't come back. anyone know if this spacer will fit my car? it's only listed under the MK4 parts. BFI says they haven't tried it. I'm really sick of clearing this code 2x a week, and i don't have the money for a new cat.
