It would appear that my long run of trouble free motoring in over. I had a full service carried out on the car last week and out of curiosity I did some code reading at the weekend to find that the EGT sensor fault is showing again. 17868 Exhaust gas temp sensor 1 (G235) Implausible signal . P1455 - 35 - 10 Intermittent. I had this sensor replacing less that 2 years ago , can these things fail so quickly ?? Or could it be possible that something else is causing it to fail ?? This fault is the only one registered on the ecu so it doesnt look like its a knock on effect of another problem somewhere else. Any thought would be appreciated. Cheers. Sean.
