Hey guys new on here. I have a 2009 a4 2.0 178bph. The problem is everytime I fill her with diesal she starts smoking blueish white smoke gets heavy when idle. And when the foot is down she smoking too. Sometimes smell it in car . Also when the fuel level is on the red. You woukd swear she was sound. Not a bit of smoke anywhere. I've changed the turbo, egr and heat plugs. Any ideas what else it could be. 🤔
cheers in advance.
