hi guys i am new to this,so here goes. the turbo went on my A4, i have replaced it with another standard one. after fitting it and starting the car there seems to be an oil leak from the egr cooler(maybe?/)pipe but it's not from the flange,it looks like it' coming from a split in the pipe. and also there is a lot of black smoke coming from the exhaust. I have been told that there could be oil sitting in the exhaust from when the turbo went? But i would be very grateful for any help you guys have.


sorry didn't realize how long i waffled on for lol
