The 1.9L as larger nipple! maybe it's a 1.9L?

Those thank (i assume you are speaking about the expansion tank) are easily
available at the dealer, they are 5 time better than any after market one...
 lately, i have a lot of problems with after market one... the good news, VW
as them and for a better price! yea, that is righ!

EX tank have a very big role on our van, buy the good stuff!

That infamous crack is a classic... they all crack at the same spot, the
after market one crack at the seam/junction. Some even inflate as big as a
soccer ball.

i forgot to publish that page on my site... well, like many other page just
sleeping on my computer:

there was the crack I expected at the seam, but also it was cracked on top
near the cap. The crack at the seam is new (or wasn't seeping before) -- I'm
curious if the other crack could have been there for awhile... thoughts?

the replacement tank a friend delivered from his shop is 100 121 035. It's
obviously not the right part (top hose nipple is way too large), but I'm
curious what it's really for. Any ideas?
