[Vwdiesel] Injectors

[Tad]

Travis - just a couple of thoughts - could this "grime" you speak of be
algae growing in your fuel?

And re: the battery - assuming your 04 is similar to my 01, you can
substitute a group 48 for the wacky OEM 97R or whatever it is, it fits just
fine (a little less wide is all) has the same capacity, and a hell of a lot
easier to find(and a little cheaper too IIRC).  In fact the 48 was spec'd
for older B4 TDIs... no idea why they changed it.
