hi guys, new to this, cant get a garage to fix this issue, so hoping someone out there can help me out.i have a a4 (55) 2L tdi s-line. I have now fitted 3 turbos to my car, i approx get 3 months drive out of it averaging 100 miles a week. I have changed oil feed, oil pick up in sump, n75 valve, breather in rocka cover, egr cooler, egr valve and boost pressure valve and this week the 3rd turbo is showing symptoms of failing. not sure what other info you need but feel free to ask........thanks
