    Check your pipes from/to turbo all way to the inlet manifold, reckon could be a loose 1 if someones been messing with piping for egr, also check any connectors are pushed home ok.

    Which engine code was that on & if it was a bkd then it doenst have an n75 as such, it has a solenoid valve block that actually houses various valves, chances of that going are slim tbh if turbo goes.
