Here's a list of mechanics who others have used. Be careful because I have seen some of the cars that have come from these mechanics and they had obvious problems that should have been fixed by a real TDI specialist. Other people have had similar complaints or other complaints about customer service. Some of them aren't licensed businesses. That's not a knock on skill level since they might do great work, it's a caution on insurance and liability. It doesn't take anything to get on this recommended list other than a recommendation. https://docs.google.com/View?docID=0ARLui1Im8fhPZGoyYjR3d18wY2JqMnA4ZHQ&revision=_latest

There's no "certified" recommended list if that's what you were looking for. It sounds like an ambitious project, good luck!
