I am a new Jaguar owner, any help would be greatly appreciated. I can't find the VDP forum but I've owned my 2002 VDP for 29 days and it has been great until today when I had P1384 & P1396 show up. I was getting on the freeway and it lost some power then I heard a knocking sound, bummed!!! I'm worried that it is more than just needing a thicker oil since the knocking became loud so quickly. I am a new Jaguar owner, any advice would be greatly appreciated!
