I debated posting this up since it's such a minor part; but I think it's important to underscore the idea that inch by inch - it will get done....
this is the tube that connects the intercooler to the turbo - and good way to get a more reliable 300 tdi and more hp is to eliminate the egr system... this is a pain because it's chalk full of dirt, diesel, and oil - and they brazed it... who brazes anything anymore?!!! ah well, so the PITA is closer
for those who don't weld - brazed joints TIG welding a pain because it pushes away the argon shielding gas
that white chalk is part everdur and part weld contamination
