My 2013 has been giving a P003A error regularly for several months (boost control position not learned). I can clear the code but it comes back after a few days. The dealer says the vanes are likely stuck and they want about $2000 just to tear it apart and see if that is the problem. I thought I would do it myself and now I am wondering if that is a good idea as it appears removing the downpipes and up-pipes may be much more difficult than I thought. I have a Haynes Techbook but it only goes to 2012 and it appears the pipes can be removed without too much difficulty on those earlier models. I have the ALLDATAdiy repair guide and it recommends dropping the tranny to get the downpipe out for a 2013 but I am not sure that will help much. One site says the downpipe can be lifted up and around the turbo, but there doesn't seem to be enough room to do that. Other threads talk about removing the cab. I am sure not going to do that. Is this indeed going to be very, very difficult? I have much of the "easy" stuff off but am hesitant to tackle the pipes. I can't find a thread or site where someone has replaced a 2013 turbo. Any advice is appreciated.
