I have 997.1 TT that keeps coming up with EGTS fault codes P0546 and P0549. The temperatures appear to be stuck on 1100 degrees C when enter through PIWIS tester. Have replace the EGTS sensors and still have the same problem and reading. Any thoughts? or does anyone have wiring diagram for the multi plug that connects to the block for sensors?
