In the past, when I went on your parts website, it would let me identify my year, model, and trim level--2008 Porsche Cayenne S. Now when I try to order parts, the drop down menu only lets me identify year and model--no trim level. Earlier this summer I tried to order an oil filter kit for my Cayenne but your website would only let me identify it as a 2008 Cayenne and it would only give me the filter kit for a V-6, not the V-8 the S has. Does this need to be corrected?
