Yep! get rid of the EGR...I'm finally getting it done.. especially with the failures of the dpf twice and the egr filter and now the updated "non egr filter" dealer puts in.. GOD knows how much soot etc.. is getting into the intake and turbo! Of course please correct me if I'm wrong Gurus..
I'm no guru but let me ask a couple dumb questions: does your neighbor drive a TDI also? What year?
We've been told time after time that the ULSD stuff should result in minimal intake clogging. That and running your car on boost like it's meant to be (not babying it) should keep the intake tract free.
Then again, we don't know what the EGR duty cycle is but based on the "fix" we can assume it's higher now than it was originally.
I don't think there is any particular additive you can use that prevents it from clogging (if it's going to clog), I think it depends more on the quality of fuel itself and your driving style.
