I've not had the car too long, but I was initially impressed with the 40 mpg pics that I posted above.
I discovered how to do the diagnostics check after testing it out with my obd code reader (no codes showed with that). However, checking the diagnostics I saw the code t--- which indicates an injection fault has been detected for a minimum of 4 seconds in the past at some point.
The car was and has been driving fine both before and after I reset that indicator approx. 250 miles back. The code hasn't returned.
Now here's the glitch in the matrix. On my 40 mile round trip commute of generally town / urban driving with around 8 miles of dual carriageway thrown in at speeds of up to 90 mph but generally 65 - 70, the car is now achieving up to 53 mpg.
I've checked and double checked and it seems kosher. Am I missing something that I'm not familiar with on these cars? Could this be really real? Or, is there some trick going on with the electrical system?.. If not then it's much better than I could have wished for on a car with 125k on the clock. Please tell me it's real.
