Recently started to have an issue with my V50 2.0 diesel 2007. The car is very sluggish below 3000 rpm. Driving at highway for 3 hours straight and the throttle has no response at all. I also get engine check warnings quite often.

Friend of mine has vida diagnostic and it showed only one fault: ECM-2263 Turbo control faulty signal

By clicking on the error, it showed picture of turbo sensor (pressure transducer) so we replaced it. Drove it for a week and no change in performance. Run a diagnostic again, and the same error showed up, even though it was erased after replacement.

Could this be a broken wire issue, hole in a hose somewhere? Any help would be appreciated, no good volvo specialist in my area...
