Audi A4 b6. Blue smoke coming out of exhaust
I recently got a cat delete pipe and 3 inch straight pipe done on my 2003 A4 1.8t and since then blue smoke has been coming out of my exhaust during idle and tons when I give it a little gas in first second and third gear. Anyone have any ideas on what the problem could be ?
