my car is at the shop, I am having emissions issues, all parts turbo, exhaust manifold, turbo vanes have been removed ,cleaned....changed n75 valve, air intake, injectors, injector connections, still have no boost, turbo is good, and blowing black smoke and in limp mode. Would it just be best to replace the brain?

well I don't currently have the list in sight...but what I remember are low boost, open circuits, maf code, o2sensor, injector 4 misfire, which brought me to the conclusion since we changed the n75, changed the injector electrical supply, put in a new injector, changed the maf, the air filter that this is probably a computer issue. we also had the mechanic clean all the exhaust parts, manifold, egr, turbo and turbo vanes, actuator got all the soot out of everything.

Hey KLMOSIER,

This is a strange problem and ever more difficult when we are not in front of the car, did you ever get it figured out?

Best, Ken
