Code P0491 and P0492 ????

Hello all, I have a 04 cayenne 3.2 base model, I have a P0491 and a P0492 code, and when I google it up, it only shows the V8 or the twin turbo model, any help would be appreciated, thanks.

Should be the same thing...the codes are pretty universal. Either the secondary pump or related fuse. I have had to replace both pumps (one twice). in my 2004 TT...and a couple fuses.

I remember my buddy had the same codes and it was because of a cracked vacuum tube.
