Hi I want to access the turbo vanes without having to take the turbo off. I know it's possible but I just want to know what's the recommended parts of the engine to take off in order to get better access to the turbo on a Bkd engine (a3 2004 TDI). What I know I will do so far is d/c and remove the metal pipe between the egr valve and the manifold. Iv attached a picture of what my engine looks like. Any help will be appreciated.
