Weird how they didn't honor it. When did you contact customer service and did you get a response back from them as yet?
My 06 jetta has a cartridge filter. The dealer wants $20 but the local parts store sells it for $10. Same German manufacturer too. Mann.Just out of curiosity, wonder what a Cummins change would cost in comparison? Wonder if the filters and what not are a more common part number and are therefore cheaper? ? Don't know myself just wondering. I know the new style "cartridge" filters are much costlier than my old tg-16 frams I used to run in my old gasser.
