    Default 2004 XC90 2.9 Turbocharger issue

    Yesterday morning my XC90 threw a 0234 code and it feels like the turbo has been disabled. On inspection I can see an oily mix is being sprayed out onto the pipes that lead to the turbocharger as per the picture. Any idea on what is causing this? Thanks for any input.

    P0234 is a overboost related code. A common failure is the plastic pipe from the turbos to the intercooler cracks, causes funny noises under boost, air leaks, - 30636959 - it cracks where the two pipes join together -
