Check Engine Light: Temp Sensor
This past week our GLE450 SUV with 10,387 mile experienced a Check Engine Light (CEL) which the dealership diagnosed as a fault: "ME for code P146264 TEMP sensor in FP control unit. Found LI47.50.P-070263 Software parameter unit is faulty." "This LI will be updated once SW solution is available." Right now, the dealership does not know when MB will come out with a fix for the fault. I have reached out to MB CS and see what their response will be. While the code was erased, the CEL came back again and it was confirmed that it is related to the original fault. Now, we wait.....
