Just scanned my car with my VAG-COM and found the following codes...
Engine
17544 - Fuel Trim: Bank 1 (Add): System too Lean
P1136 - 001 - Upper Limit Exceeded - Intermittent
16795 - Secondary Air Injection System: Incorrect Flow Detected
P0411 - 002 - Lower Limit Exceeded - Intermittent
16804 - Catalyst System; Bank 1: Efficiency Below Threshold
P0420 - 002 - Lower Limit Exceeded - Intermittent - MIL ON
I do know that my turbo is on the way out and have one on order. Do you guys think that the above codes are the result of my dying turbo? If not what else could cause these codes?

No turbo failure there, looks like a vacuum hose leak in the secondary air system.
Many people have fixed that issue and posted here. Do some searches on the codes and then start inspecting under the hood. My guess is one or two hoses will address all those codes. You may find your turbo is just fine, it's the vacuum leak causing a performance issue. Hoses are a lot cheaper than turbos!
