Evening all after some more questions if anyone could help?
Iv got the A4 2.0tdi Blb I took the air filter box of and hose to give it a clean and I saw it had Brown gooey crap inside the hose also noticed in the hose coming from the side intercooler to egr ( I think that's what it's called). Is this bad?
Another thing is my turbo takes a while to kick in, in all gears.and when it does it makes a whistling noise is this normal?
Thanks in advance
