Mine was the passenger side..My TT was completely stock so it was more of a bitch to remove certain things (for example the EGR bolts that run into the back of the lower intake manifold) -Those of you who know what I mean, you know how bad that is....everything is just so tight as you know...lots of patients is required. I would definetely do it again with the engine in the car if I had to, if that helps you...otherwise I can help you with every step through email if you'd like. Let me know...here is a link to pictures I took of every step of the way..
