Not sure but if you're talking about the turbo oil line, no.
No problem, there is a donation button at the bottom I think I'll move it to the top though.Thanks for the reply Chitty. It actually all went well! the loud hissing is gone and no leaks anymore! now I wish I had taken video n pics of the job, to help out the forum. This forum has done so much for me n my Jetta, I have to start giving back!
I figured it out myself- the turbo oil line definitely has to come off to allow the EGR cooler to drop down, even after some twisting and maneuvering.
This is not a bad job, but not one for the novice mechanic. (I have not turned wrenches in a long time, but my good basics and instinct came into play) My advice is to take your time and use quality tools, so you do not round anything off. I'm also coating some of the hard to get bolts with anti-seize in case this thing needs replaced again.
One thing for sure- the EGR cooler removal steps in this previous post below do not even come close for the 2006 Jetta, as nothing has to be done from the top.
Now that I'm a one-time "expert", feel free to contact (me) if I can be of assistance.
