It says SAAB but they have great tech support. They might be able to help you just call them or XS Power.
People on here are going to tell you to go to or call a deisel repair shop and ask them. Every deisel shop I spoke to say that they would just replace the turbo or send it to a deisel turbo repair shop in another state.
