NicoN Posted November 1, 2024 Author Report Posted November 1, 2024 I started this topic a long time ago. I simply noticed that your CDT needle did not move at all A shop diagnosed the indicator as faulty, but it was never changed. Trying to find out what to do, I simply disconnected the sensor and measured the resistance: overload. Then I shortened the wires to the instrument with master switch on - full deflection. So instrument is fine. we then replaced the sensor and CDT is working since then. My experience: during takeoff, at sea level CDT was never an issue. The needle is moving a little but never critical. The higher I climb, the more CDT is rising. I saw situation where I had to lower the power as CDT was approaching the limit temperature.

Have a look at any modern turbocharger, it's application and what limits it's life in the application. Operating loads on the compressor, which include pressure and temperature, limit the life due to fatigue. I'm not a big fan of the prove me wrong approach, it tells people what they need to know.
