Thats a low boost circuit A code. Hows the turbo comp wheel look? Hows endplay and up/down play in the shaft? It could also be your map sensor. I am not too keen on this one, I did have this code come up, but I was loosing oil pressure. I fixed thaty, and rebuilt my turbo, and no more code. Some one else will be along and help you better.
